The Recap of INT Chain 2nd Anniversary – First YouTube AMA

The Recap of INT Chain 2nd Anniversary – First YouTube AMA
https://preview.redd.it/assk6hfe2bi31.jpg?width=1250&format=pjpg&auto=webp&s=34c3472095bf8c388113154f2b7c17518cd003c4

Hello everyone, time flies very quickly. In the twinkling of an eye, INT Chain has been two years old. During these two years, I have received enthusiastic help from INT investors and many friends around the world. Thank you, thank you so much.
We want to hold an AMA on the occasion of 2nd anniversary, to communicate on some of the issues that everyone is most concerned about. I hope that everyone will continue to support us. Said Mr. Yin Xiangyu, head of INT Chain China.

1. Technology

@Quengor
Q1: The rewards of the storage of INT tokens are distributed until 2023 by the INT Chain team. If INT is financially independent from the network fees before that date, what happens to undistributed rewards? Conversely, if in 2023 INT is not independent, the project will have failed (which I do not want)?
A1: 2023 is the milestone of first phase, in this first phase we will upgrade our mainnet several times. Meanwhile, we will adopt some suggestions from community to improve currently mainnet. The optimization of economic mode and incentive mechanism will also be conducted. We believe by the year 2023 we will have a more perfect mainnet. If we do not change the incentive mechanism by the year 2023, we will consider continuing with current node plan with half incentive reward.
@bastian-jaro
Q2: When will the nodeplan/ number of nodes be updated?
A2: The development of new mainnet is ongoing, after the new mainnet released we will update the new node plan. We expect it will be updated from the end of 2019 to 2020, it will depend on the situation of development.
@Vol_Har
Q3: What's being built on INT? Only projects/Dapps by the INT team or are other developer teams working on INT apps? And if so, can you give some examples? BTW: is there an official INT SDK?
A3: In the past several months, INT team and more and more developers have jointly developed Dapps based on INT Chain; INT Team has completed Smart Wallet, Referendum system, Smart wallet game, and optimized router App. Meanwhile, an IoT and Staking product is in progress. the developers are getting more and more active, currently, there are many teams that have contacted INT Chain, the projects cover Internet of Vehicle, smart traffic, smart home, Hydrological monitoring, Welfare and etc. We will host Dapp development competition to promote Ecosystem of Dapp development. INT Chain has official SDK, for more information, please refer to the official documentation: https://docs.INT Chain.io/
@Taliki
Q4: How the IPBFT consensus does work? And what will be the TPS per chain with it?
A4: IPBFT consensus algorithm has many optimizations based on current mainnet’s consensus algorithm, the optimization covers performance and security, and the node number will be increased, meanwhile, incentive mechanism will be improved.
Current mainnet’s tps is 2000, in the coming future the tps will be increased profoundly.
@axelsega
Q5: Regarding interoperability, do you think some subchains could be connected to other networks such as Binancechain, tomo or ethereum?
A5: Cross-chain and sub-chain are one of the most important technology research directions. In the roadmap we have described very clear, we had made big progress, and I think making our sub-chain connected to other networks is possible. But the technology required some time to achieve.
@80558055
Q6: Why do you need our private key's to "check" that these are our coins if we want to migrate from the eth blockchain?
A6: It is necessary to have ETH private key. 1. It requires private key to burn ERC 20 token in Ethereum. 2. The private key also demonstrates the ownership of the tokens. Just one reminder, the mapping process which uses Private key to do signature is executed offline, INT Chain doesn’t get or hold any private key from users.
@hengkyhks
Q7: If your project fails in your roadmap or whitepaper, what should you do it to make it right?
A7: Blockchain technology is developed rapidly, INT Chain team also very aware of this, most blockchain projects will not exist in the future. So we have to keep optimizing and improving, our tech will also be improved according to development of Blockchain industry. Keep upgrading and keep moving forward.
@Quengor
Q8: The tests of the new mainnet are validated, do you have an official release date?
A8: The research and development of the main chain have always been the primary work of the INT Chain. After the mainnet was released on January 16th, 2019, we did not have a moment to stop. While maintaining the original mainnet code, the research and development work of the new mainnet is also continuing. So far, the expected results have been achieved. The new mainnet code is being debugged, and the blockchain explorer and wallet of the testnet are also being developed and tested, due to the large amount of testing work, the specific release time is not defined. We are waiting for the technology to be ready, will inform the community as soon as possible if there is any update.

2. Application

@hengkyhks
Q9: What type of devices (apart from the router) do you think will be the first to use INT CHAIN? Home devices? Smartphones? Smart city devices?
A9: Currently, from the perspective of our cooperation and technology research and development. Proof Data Storage and Desensitization Data should be the most used case, like smart city device, included. In the project of the Hubei Smart construction site that we disclosed earlier, INT Chain related technology is applied. Including the smart parking project that we are still in contact with and explore, it is a scenario where INT Chain related technology can be prioritized.
@bereanma
Q10: What is the capability/use of IoV device?
A10: The functions of IoV mainly include: driving data analysis, remote diagnosis, security alarm, location tracking, driving analysis, etc.
After INT integrated, it will mainly cover big data sharing of desensitization data, as well as token incentive and privacy protection.
@龚翔宇
Q11: What’s the R&D and promotion plan for the Internet of Vehicles device, how will the partner promote the device, and is there any connection between the Internet of Vehicles device and the INT token?
A11: At present, the research and development of IoV device are proceeding according to the plan. Our original plan is to launch physical products in the third quarter of this year. The cooperation of promotion and sales is also in progress. Once the products are mature, the promotion will be fully launched. Keep an eye on our official news.
OBD is related to INT. Users can get certain Token benefits by sharing data such as driving data and car condition data. We are also discussing with our smart transportation team to upgrade our products to an IOV/ITS INT ecological project.
@Quengor
Q12: The new version of the router (in partnership with China Telecom) will be compatible beyond the Chinese territory? For example: in Monaco (France) because the 5G is already deployed.
A12: Currently the Esurfing Blockchain router version i1 had been released, it doesn’t support to the market outside of China. We are working on the second development phase of the router, it will integrate the function of Smart home, and we are testing INTFS system.
We will release new version of Router for market outside of China.
@hengkyhks
Q13: Is the blockchain router going to be connected to the new mainnet and be part of the network as a node?
A13: In our initial tech design, router is being a light node to connect to mainnet.
@axelsega
Q14: Do you think the router could be a path to interoperability if it can allow all blockchains and smart contracts to communicate with each other (including oracle)?
A14: This is a good question. Router is a gateway device, which can be a hub of communication between many IoT devices. In the future, with cross-chain system become more perfect, and the router’s performance increase. The router can play a very important routing role throughout the blockchain ecosystem.
@Quengor
Q15: I would like to have more information about the construction of the connected school in Quzhou. Where is the construction? Which equipments equipped with INT technology?
A15: INT participated in smart city project of Quzhou City, Zhejiang province, including Smart Campus, Smart Prison. Regarding the Smart Campus project, this involves multiple systems: IoT system for intelligent classroom,
Anti-theft system for Campus, Student behavior monitoring system, Video proof storage system. INT Chain technology is mainly for distributed data storage and encryption.
@hengkyhks
Q16: Can you put some light on your partnerships? How are they helping you out in your project?
A16: Currently partners like China Telecom, ZTE CLAATEK. On the one hand, INT Chain has carried out research and development and application in the IoT blockchain field; in addition, partners provide us with a large number of end users and sales channels.
@axelsega
**Q17:**In 2018 report was stated, that in December 2018 JIC Capital invested an additional 1 million US dollars for promoting the development and ecological layout of INT Chain in the IoT field. Could you elaborate in more detail what are the main parts of marketing budget and what were your goals, how you measure them? For example, we saw a few really nice initiatives on twitter to build a larger community and awareness, but community size in TA groups still the same as it was at the beginning of 2019. So do you feel that your marketing strategy is doing ok, or maybe you have plans to expand it, make radical changes, or maybe hire PR and marketing professionals?
A17: Most of our investment, include JIC Capital, are invested in R&D of Mainnet and development of blockchain products. To build an industry ecosystem for IoT blockchain requires a lot of cost money.
We are not doing well enough in PR. We are working hard to improve, and we are looking for more excellent PR and operational talents. We have also increased the budget for this aspect since the beginning of this year. I believe we will achieve better results.
We also welcome our community investors to give us more advice and let us work together to achieve this goal.
@axelsega
**Q18:**INT completed project for prison, won project for primary school, made partnerships or negotiated with businesses in different fields (gaming platforms, logistics, bus stations, blasting factory and etc.). It looks like the team wants to participate and achieve everything. Don’t say it’s a bad thing, but it definitely has its weaknesses because all these projects need resources – time, labor, negotiating. Is it part of a major strategy or INT just need the money so badly that they have to chase every opportunity to earn it instead of focusing on making a platform for Internet of Everything?
A18: As we all know, INT is practicing the engineering route. The core of INT is to focus on building a platform for all things. We need to verify our technology and products through some projects. Through these projects, we have accumulated valuable practical experience. At the same time, gradually build the application ecology of INT, and these projects also provide us with some money, which is undoubtedly a very good thing for INT.
Of course, these projects are all handled by the specific executive team. INT's core development team has always focused on the development of the INT main chain, they will not take time for these projects.

3. Partnership

@hengkyhks
Q19: In February 2018, for your first meeting, Dr. Xiang said you were developing a blockchain OS kernel with your partners such as HUAWEI. Do you think this OS kernel can be included in a blockchain mobile in the future? Maybe link to Harmony OS?
A19: At present, the blockchain operating system developed by INT and Huawei has made initial progress. The basic block platform is under construction. As for whether it is applied to the mobile phone operating system, it is not yet available, but I believe that access to the mobile phone system is possible in the future.
@Energy
Q20: Why does INT Chain disclose partnerships?
A20: At present, we have posted some cooperation announcement, such as China Telecom, Hubei construction, etc. For those partners who are not been announced, mainly because of the commercial confidentiality of the cooperation, we are not allowed to post official announcements before the cooperation is determined. We will post the latest cooperation announcement as soon as possible.

4. Team and prospects

@Energy
Q21: Can you explain the role of INT in the IoT and why the IoT needs to be combined with blockchain?
A21: The answer is yes! With the convergence of technologies such as 5G, blockchain, AI and edge computing, the era of the Internet of Everything will soon come, and the data economy and the machine economy in the era of Internet of Everything need blockchains.
The blockchain can not be falsified, value transmission, and the characteristics of smart contracts. It is very important to the Internet of Things economy. On the one hand, it can solve the problem of identification and privacy protection of Internet of Things data very well. Second, the micro-transaction between IoT machines can guarantee the authenticity of the transaction through the blockchain. The third is in the era of the machine economy in the Internet of Things industry; the number of connected people will be ten times or even 100 times that of the number of people currently connected. In a large amount of resources, data, energy, and machines, only based on smart contracts can automatic implementation. transaction.
@Racouline
Q22: We are in a period of uncertainty when there is a possibility that we are going into recession. China had its weakest industrial growth since 2002, the industrial war with Huawei can have long term impacts in China. How is INT Chain team prepared to succeed in that environment?
A22: First of all, we still have confidence in the Chinese market. China's GDP has reached the second place in the world, and it can still maintain a growth rate of 6.7% in 2018. This speed is still in a fast-growing economy around the world. Moreover, China has the largest middle-class group in the world, and it is a huge market that cannot be ignored in the world.
Despite the global volatility of the economy, we are still optimistic about the blockchain technology and the reference of blockchain technology in all walks of life, and it is precise because of this that it is a huge opportunity for us.
INT Chain is a blockchain public chain project with nodes all over the world and will not be affected by a single market or territory. Of course, we also see Huawei's technical warfare, but we are very much in recognition of Huawei's efforts in application and technology. This is where INT Chain continues to explore and ultimately guide INT Chain to success.
@hengkyhks
Q23: Can the INT compete with existing tokens? If the answer is YES, What's the main advantages of INT that will have a positive impact on the crypto industry?
A23: INT's competitiveness can refer to feixiaohao.com. Among 1000 crypto projects in the world, INT can be ranked within 150 for a long time, which explains the competitiveness of INT project. The main advantages are three major pillars: technology (INT mainnet, wallet financial ecology, DAPP), community (global community), landing application (Esurfing blockchain router, OBD equipment, enterprise application solutions), the value and advantages of INT, are also reflected in these three cores.
@Energy
Q24: Can INT break through and lead the development of IoT?
A24: INT Chain is a project which focuses on building blockchain related IoT application, but Rome was not built in a day. Only by making each small achievement, and we will reach to the success.
@Energy
Q25: Is INT's next plan handed over to the community? The founder left? Is it really maintained for the community? How to ensure that it will not be a bad ending?
A25: We need to understand two concepts: community and communityization. The communityization of INT is based on the INT team, gradually bringing more community governance and other work, so that investors can participate in it. Participate in the construction and development of INT like a partner, but we will not leave, we can do a separate AMA for communityization, and everyone will talk about how to make the INT Chain community better.
@烟雨随风
Q26: What is the company size? And how many employees? Is the company currently profitable or losing money? If it is profitable, what is the major income source?
A26: There are nearly 60 people on our team. The main source of income has two parts: one is the To C business, the sales of routers and other devices; the other is the To B business, providing blockchain application system for the enterprise and the blockchain technology solution.
We will release the INT Chain 2019 half year’s digital asset report in September.

5. Exchange and price

@Energy
Q27: Is there a big investment institution to support INT? Will INT be the second NEO?
A27: Actually, I think community and INT Chain team are our powerful and secure backing, both of them to support INT development. As for the institution, it is an auxiliary role.
In fact, regarding of genetics, development, and future planning, it is different from other projects.
@Energy
Q28: Why are the institutions that invest in INT very small, and why are there no institutional investments such as Danhua Capital, Node Capital, Liaode Capital, and INBlockchain? Is that because INT is not strong enough?
A28: When INT started private sale in May 2017, these institutions did not exist. After listing on the several exchanges in the second half of 2017, the need to raise funds is not an urgent need.
In the following cooperation with some institutions, we mainly look for institutions that are helpful to the development and ecological development of INT Chain.
@bastian-jaro
Q29: How soon will there be a new exchange? US citizens still cannot legally purchase INT and volume on OKex is quite low...
A29: The layout of INT Global Exchange has been initially completed (OKEX, Bitfinex, Coinegg, Fcoin, Yex, Coolcoin), and we also contact with different major exchanges. Our community, R&D, ecosystem, etc. have been recognized by them. The specific time for the online launch is still uncertain. This is a complicated process involving the docking between the team and the exchange. We will share our news on the official channel.
@晴天
Q30: What do you think the price of some coins has risen a hundred times? Does INT have the potential to the 100-fold increase in price?
A30: From the perspective of market, a 100-fold increase in price indicates that the bull market has arrived, which is a very good for the overall market; from the perspective of the project, it shows that egt was seriously underestimated in the early stage. At this point, we believe that INT is the same.
IN 2017, INT rose in price from 0.28 to 7.3 yuan, up to the 20-fold increase in price, which showed INT has the potential to the 100-fold increase in price.
@Energy
Q31: Can INT break the historically high price?
A31: Both INT Chain team and our investors believe that the value of INT is underestimated. And we all hope that the price of INT can reach 10 RMB this year through working together with our community members. And all investors can get attractive returns.

This AMA is complete, and Let's look forward to the next time AMA, Thank you all for reading! We can create more opportunities for AMA in the future. Thank you again! I hope we can move forward together. To make INT better!

Top 5 Misconceptions About Blockchain

When we are faced with a new technology, we often look for analogies to understand and describe it. To bridge the knowledge gap, we seek analogies from the universe concepts familiar to us.
In our search for the right analogies, we often risk misunderstanding this new technology. Blockchain technology has introduced a paradigm shift in the way we organize ourselves to generate, account for, transfer and store value. Yet, we are still in early stages of understanding its importance.
In this post I will try to shed light on the top 5 major misconceptions about digital assets and about the open blockchain—a technology that underlies them.
1. Blockchain, not bitcoin
This misconception stems from failing to realize why blockchain exists in the first place. In essence, blockchain is a shared ledger designed to function in an extremely hostile, open environment. It derives its value from the security of its tamper-proof records.
In the blockchain networks powered by proof-of-work (PoW) algorithms, that security is achieved by miners competing to solve a computationally intensive puzzle. The miners do this with the expectation of receiving a digital token as a reward. This digital token can be freely redeemed for fiat currency to cover their operating costs and generate profits. These open systems are designed in such a way that value of their token ultimately dictates the level of security of their network.
When we decouple the concept of blockchain from its underlying token, it simply wipes out most, if not the entire, value proposition the blockchain as a concept.
Implementing blockchain as a token-less system of recordkeeping within a single company is perhaps the prime example of this misconception. Such an endeavor fails to use one of the most valuable properties of the open blockchain. Implementing a blockchain solution in such settings may even be counter-productive especially when better alternatives exist, in the form of databases with proper access control.
Blockchain could be useful in a commercial setting where a consortium of companies decides to use a single ledger to keep track of important transactions. An example of such transactions could be shares of companies that are traded on Wall Street millions of times each day. These transactions are reconciled periodically between the financial institutions by a trusted third-party entity, which could be ultimately replaced by a blockchain-based protocol at a fraction of their cost. That said, these systems may never become as secure and tamper-proof as the open blockchain as the security of the network depends on the number of its minestaking nodes.
2. Exchange Hacks = Digital Assets Are Not Secure
Centralized digital asset exchanges are popular avenues for exchanging digital assets for currencies such as USD or other digital assets. However, their design creates a system of incentives for external or internal actors to compromise them.
When we hear about exchange hacks in the digital asset space, it almost always involves compromising the security of an entity that operates within the traditional server-client architecture. However, the mainstream consciousness conflates the digital exchange security with that of technology that underlies digital assets. Holding a digital asset in a cold storage is extremely secure. Holding it in an exchange is not.
3. Blockchain has low TPS, hence it will never compete with or replace traditional financial infrastructure
Traditional financial systems process a vast number transactions every day. This transaction processing capacity is called throughput and is measured by a metric called transactions per second (TPS). Payment networks such as Visa claim to process up to 56,000 TPS, while traditional exchanges are likely to have much higher capacity to process transactions to accommodate high-frequency trading.
Today, the Bitcoin network processes around 4-5 transactions per second while the second largest digital asset network—Ethereum processes around 15. If we compare the current state of the blockchain technology to the demands of the global financial industry, it is easy to see why such claims could be justified. However, this is a myopic view of this new technology, very much akin to the way Kodak dismissed digital cameras as a potential threat to its business model.
It failed to recognize (i) the speed at which digital cameras would develop and (ii) the fundamental shift the digital cameras introduced in the way we take and store pictures, despite being the company that invented digital cameras in 1975. As the history shows, that was Kodak’s grave mistake.
It is hard to ignore the historical parallels here. The digital asset space is evolving fast. The next-generation networks, which operate under the proof-of-stake consensus mechanism, preserve the securities of proof-of-work, but do away with its capacity limitations. A notable example of that is Cardano. These new networks also represent a shift in the global economic paradigm that many do not seem to notice.
4. Digital Assets Have No Intrinsic Value
The concept of intrinsic value, or lack thereof, is often used to describe digital assets as a purely speculative asset class. While this may apply, with some justification, to digital assets which only claim to function as money, such claims fail to capture the wider nature of platform-based digital assets, which derive their value from the direct use of their networks.
In digital asset platforms like Cardano or Algorand, the native token gives the holder the right to participate in the consensus of the network through the process of staking. The consensus mechanism secures the network, maintains the decentralized ledger, enables participation in the governance of the network and can sustain myriads of decentralized applications with real-world utilities.
Put simply, digital tokens may derive their value from the economic activity that takes place on their networks. The economic activity on such networks, in turn depends on the security of the network, its technical capabilities, its transaction fees and the real-world utility of decentralized applications that reside on them. In that respect, they can be thought of as a new kind of financial instrument. The kind that seamlessly combines the properties of currencies, commodities, and shares of ownership into a single digital token.
These new instruments require that we develop and apply new analytical frameworks to value them, much like the concepts of equities and derivatives did when they first emerged as new financial instruments.
5. Developed Economies Do Not Need Blockchain Technology Because They Have Well-Established Financial/Commercial Solutions.
While it is easy to see how the blockchain technology could unlock a lot of value in the emerging markets, the idea that developed economies do not benefit from this technology is short-sighted.
It is akin to saying that cell phones are a great technology for emerging markets, but developed markets already have land lines, hence do not need them. In a similar vein, we could argue that developed countries do not need internet because most of what internet could do already exists in analog form.
We have to realize that (i) at its core, blockchain is a paradigm-shifting infrastructure/technology and (ii) despite its nascent stage, blockchain is extremely cost-effective… To a degree that it has the capacity to fundamentally disrupt a slew economic sectors out of existence, from banking to real estate, and create new ones.
When we accept this eventuality, we will have to face some uncomfortable truths that many sectors will not exist in their current form or entirely disappear. Currently these sectors provide economic value, employment and generate taxes. If some blockchain-based solution is to replace them in 3-5 years, where would that value migrate? Losing them to open blockchain networks would not be acceptable politically or economically for many developed countries.
One way out of this could be for developed countries to invest in national networks, allowing them to reap the benefits of this new technology, while retaining value from economic activity of their citizens and companies within their jurisdictions.
Another, more realistic way, would be to invest heavily into friendly legal frameworks that would encourage both individuals and companies that would ultimately develop or maintain open blockchain protocols migrate to these jurisdictions, drawing in talent, capital and innovation.
One thing is becoming increasingly clear: we can no longer ignore the elephant in the room. Much like digital cameras and internet itself, blockchain is unstoppable.

OneSwap Series 4 - ABI is not the invisible man

In the past development of programming languages, ABI (Application Binary Interface) has played a vital role. The function call syntax in the source code can be understood by programmers, but not by machines, which can only understand binary data. Whether the parameters should be passed through the register or the stack, the order, and the arrangement of the members of the structure parameters... all these must be clearly defined when a function calls another function. That is the ABI. Under the same ABI, the functions in the binary files generated by compilers from different vendors, or even functions from different languages such as C language and Pascal language, can call each other.
Despite its importance, most programmers are unfamiliar with ABI. Why? Because the compiler encapsulates the ABI so well that programmers hardly need to care about its details by themselves. For them, ABI is just the invisible man.
ABI is also very important for both Solidity and EVM. For example, the following important matters are defined by the ABI: how to pass the parameters when calling a contract's functions; how to pass the return values of the contract (Solidity supports multiple return values); and how to pass the parameters of the Event.
Unlike C language programmers, Solidity programmers find ABI a big headache. What forces us to care about ABI in the Solidity language? There are two main reasons:
  1. Solidity is yet to be mature, and the underlying ABI is not encapsulated well enough, so programmers need to care about the underlying ABI
  2. ABI will affect gas consumption. Without much knowledge about ABI, you may consume much Gas unintentionally
Next, we will briefly describe the details of Solidity's ABI first, and then introduce some scenarios where we need to pay attention to the details of ABI.

Solidity's ABI

A contract is always executed in an EVM instance. The EVM is relatively isolated from the outside. Its stack and memory are not readable or writable from the outside. At the same time, it has especially opened up the calldata area and the returndata area for inputs. Byte strings at any length can be stored in the two areas. The detailed interaction mechanism is described as below:
  1. When an external account calls the contract, the calldata data in the transaction is copied to the calldata area of the called EVM as input
  2. When a contract calls another contract, a fragment in the memory of the EVM needs to be specified, which is copied to the calldata area of the called EVM as input
  3. When a contract finishes execution, a fragment in the memory of the EVM needs to be specified, and this fragment will be copied to the returndata area of the caller
EVM provides special instructions to:
  1. Copy the data in the calldata area to the stack or memory to understand what parameters were passed to me from outside
  2. Copy the data in the returndata area to the memory to understand what data the called contract has returned
The Solidity ABI specifies how the parameters should be arranged to form a byte string. How the input parameters are arranged in the calldata area, how the output parameters are arranged in the returndata area, and how the Event parameters are encoded as log data: these issues are all specified by this ABI. To go deep into ABI, you can refer to Specification. Here is a brief introduction:
  1. Encode the parameters in the order they appear. The encoding result is divided into two parts: head (the content and offset of the fixed-length data) and tail (the content of the variable-length data)
  2. The encoded data are in units of 32 bytes, and every 32 bytes of data is counted as a slot
  3. Integers and bool values occupy one slot. If the length is less than 32 bytes, zeros should be added to the high digit
  4. An integer array or bool array of length N occupies N slots, and each member occupies 1 slot
  5. Variable-length data types need to be represented by three parts: offset, length, and content
    1. The offset is placed in the head part, as a pointer, pointing to the starting position of the variable-length data content
    2. The length occupies 1 slot, which represents the length of the content; the content occupies an integer number of slots, and they are all placed in the tail part
    3. The length of string and bytes types is their number of bytes. The content is densely arranged in N slots. If it cannot occupy an integer number of slots, the last slot needs to be filled with zeros.
    4. The length of variable-length integer arrays or bool arrays is the number of their members, and each member occupies a slot
For the calldata for the called contract, in addition to the parameters, the first four bytes will also include a "function selector", which will be described in detail below.
If the calldata actually passed to a contract is shorter than expected, the calldata parsing logic inserted by Solidity will find that and revert execution. What if it is longer than expected? Solidity just ignores these redundant data and will not report errors.
This is a very interesting feature. In blockchains like EOS and CoinEx Chain, a memo can be added to a transaction. It does not change the semantics of the transaction but appends extra information to the transaction which is packaged to the chain as a permanent storage. Ethereum does not allow explicit support for memo in the transaction format, but we can append harmless information at the end of calldata for a memo-like effect.

Gas Consumption When External Accounts Call Contracts

The ABI of Solidity set people thinking: Aren't there too many zeros? A 32-bit integer parameter needs to be filled with 28 zeros, and a bool value with 31 zeros. In this way, in the transaction that calls a contract, most of the bytes are used to fill zero.
That is true. To reduce the Gas consumed by these zero-filled users, Ethereum stipulates that a non-zero byte in a transaction costs 68 Gas, and a zero byte costs 4 Gas, a difference of 17 times. So you will not feel that painful from the zero-filled bytes.
But we still have to note that the parameter definition of the external function is still very important for Gas consumption. For example, to pass 256 bool values ​​in, if you use the bool[256] type, it will consume 4*32*256=32768 Gas, and if you use a uint256 as a bit mask to pass it, it only consumes 68*32=2176 Gas.
In the OneSwap contracts, parameters are compressed when the number of bytes for zero filling may be relatively large. For example, the function of OneSwapToken to transfer tokens to multiple addresses:
 function multiTransfer(uint256[] calldata mixedAddrVal) public override returns (bool) { for (uint i = 0; i < mixedAddrVal.length; i++) { address to = address(mixedAddrVal[i]>>96); uint256 value = mixedAddrVal[i]&(2**96-1); _transfer(msg.sender, to, value); } return true; } 
In the mixedAddrVal array here, the upper 160 digits of each member are the payment address, and the lower 96 digits are the amount of the payment. It does not use two variable-length arrays to save the list of recipient addresses and the list of transfer amounts, as that leads to a lot of zero-filled bytes.
For another example, the function of trading pairs for deleting orders in batches is defined as follows:
 function removeOrders(uint[] calldata rmList) external override lock { uint[5] memory proxyData; uint expectedCallDataSize = 4+32*(ProxyData.COUNT+2+rmList.length); ProxyData.fill(proxyData, expectedCallDataSize); for(uint i = 0; i < rmList.length; i++) { uint rmInfo = rmList[i]; bool isBuy = uint8(rmInfo) != 0; uint32 id = uint32(rmInfo>>8); uint72 prevKey = uint72(rmInfo>>40); _removeOrder(isBuy, id, prevKey, proxyData); } } 
In the rmList array, each member contains a bool value, a 32-bit integer, and a 72-bit integer, a total of 14 non-zero bytes. Well, each member still has 18 zero bytes. To compress it further, you can make each array member correspond to two orders to be deleted, but considering the readability of the code, this method was not adopted.

Keyword calldata

In the two examples above, you may have noticed that the parameters are marked with the calldata attribute. In Solidity, all parameters passed by reference, including bytes, string, and fixed-length and variable-length arrays, need to be marked as to which one of storage, memory, and calldata the source is. If it is storage, the parameter comes from persistent storage; if it is memory, it comes from memory; if it is calldata, it comes from the calldata area. If a function has an external attribute, it cannot receive storage-type parameters, because external storage cannot be accessed from the outside. The following code segment will report an error after compilation:
function try2(uint[] storage aList) external returns (uint) { return aList[0]+aList[1]; } // Error: Data location must be "memory" or "calldata" for parameter in external function, but "storage" was given. 
If the parameter of an internal function is memory, then it can be called after other functions modify the parameters in memory; if its parameter is calldata, it means that this parameter is read-only, as other functions cannot modify calldata area.
Whether the parameter of an external function is marked as memory or calldata does not seem to make a big difference as both can do the same job. But in fact, they vary in Gas consumption. Before an external function is executed, some ABI parsing logic inserted by Solidity itself will be executed, which is to copy the data in the calldata area. Specifically:
  1. Ordinary value-type data (integer, bool, address) need to be copied to the stack
  2. Memory-type data need to be copied to memory
  3. Calldata-type data is not copied beforehand. Instead, during the execution, the external function will decide when to copy and which to copy.
For external functions, it is advised to set the parameters to calldata instead of memory, so that it can be copied on demand and save Gas.
The first "copy-to-stack" approach mentioned above sometimes leads to a headache for programmers. For example:
function try1(uint a1, uint a2, uint a3, uint a4, uint a5, uint a6, uint a7, uint a8, uint a9) public pure returns (uint) { return try2(a1, a2, a3, a4, a5, a6, a7, a8, a9); } function try2(uint a1, uint a2, uint a3, uint a4, uint a5, uint a6, uint a7, uint a8, uint a9) public pure returns (uint) { return a1+a2+a3+a4+a5+a6+a7+a8+a9; } 
These two functions seem perfect. In other programming languages, similar codes can be compiled and executed smoothly. But not in Solidity. An error is reported:
Compiler error: Stack too deep, try removing local variables. 
That is because, in Solidity, there cannot be over 16 active local variables on the stack at any place in the code. Variables declared inside the function, incoming parameters, and the parameters for calling other functions, are all considered as local variables. The above try1 function has 9+9=18>16 local variables, thus causing an error.
Therefore, when faced with similar troubles because of too many input parameters, you may consider packing some parameters into an array of calldata type, so that it does not take up stack space. For example, following Solidity code can compile and run:
function try3(uint[9] calldata a) public pure returns (uint) { return a[0]+a[1]+a[2]+a[3]+a[4]+a[5]+a[6]+a[7]+a[8]; } 

Gas Consumption of Event Parameters

To be specific, ABI-encoded data may consume Gas in the following five scenarios:
  1. An external account calls a contract, producing calldata
  2. A contract calls another contract, producing calldata
  3. A contract is called by an external account, producing returndata
  4. A contract is called by another contract, producing returndata
  5. Gas consumed by Event parameters
According to the specifications of Ethereum, the 2, 3, and 4 listed above will not consume Gas at all. Of course, when calldata and returndata are consumed (read), Gas is consumed; but when they are produced, it requires no Gas.
We have just introduced the first condition above. As for the fifth, note that: After the Event parameter is encoded as a data segment, 8 Gas per byte is charged for both zero bytes and non-zero bytes. In this way, a bool variable may consume 32*8=256 Gas. To save Gas, it is necessary to compress the Event parameters, and we will talk more about it in subsequent articles.

Understand the ABI Before You Make a Low-level Call

In the OneSwap contract, there are some strange constant definitions:
bytes4 private constant _SELECTOR = bytes4(keccak256(bytes("transfer(address,uint256)"))); bytes4 private constant _SELECTOR2 = bytes4(keccak256(bytes("transferFrom(address,address,uint256)"))); bytes4 private constant _APPROVE_SELECTOR = bytes4(keccak256(bytes("approve(address,uint256)"))); 
What are these bytes4 type variables? It turns out that they are just the first four bytes of calldata as mentioned above, that is, the function selector. From the above statement, we can see the generation mechanism of the function selector: the function signature (namely, the function name and parameter type list) is passed as a string to the hash function keccak256, and the lowest 4 bytes of the obtained hash value is the function selector.
Unlike JVM and WebAssembly, EVM has no concept of functions. The function in Solidity is nothing more than a fragment of bytecode. After the EVM is started, a function selection logic inserted by Solidity will be executed, which examines the four-byte function selector and determines jumping to the beginning of which function's bytecode fragment, through a series of if-else judgments.
In the OneSwap contract, the function selector is used in this way:
 function _safeTransferToMe(address token, address from, uint value) internal { (bool success, bytes memory data) = token.call(abi.encodeWithSelector(_SELECTOR2, from, address(this), value)); require(success && (data.length == 0 || abi.decode(data, (bool))), "LockSend: TRANSFER_TO_ME_FAILED"); } function _safeTransfer(address token, address to, uint value) internal { (bool success, bytes memory data) = token.call(abi.encodeWithSelector(_SELECTOR, to, value)); require(success && (data.length == 0 || abi.decode(data, (bool))), "LockSend: TRANSFER_FAILED"); } function _safeApprove(address token, address spender, uint value) internal { token.call(abi.encodeWithSelector(_APPROVE_SELECTOR, spender, value)); // result does not matter } 
We can apply the call function to the address of a contract, and its parameter is the calldata for calling this contract. We use abi.encodeWithSelector to generate calldata. Its first parameter is a function selector, and the subsequent parameters will be encoded as a byte string according to the ABI specification and appended after the selector to form calldata. After the contract is called, it will return two values: one is the result of the call of the bool type, indicating whether the called contract has successfully ended; and the other is the return value of the contract of the bytes type, that is, returndata. This returndata can decoded into one or more parameters using abi.decode.
This method of calling the contract is quite low-level, exposing the mechanism of EVM contract call and the details of the ABI specification to users. You may be curious: As Solidity does provide a user-friendly syntax to call functions of other contracts, which is very similar to calling functions inside this contract: uint256 govOnes = IERC20(ones).balanceOf(address(this));, why bother to use the low-level call function?
The reason is that such a user-friendly mechanism is not flexible. In the above _safeApprove, for example, we completely ignore the two parameters returned by call. In other words, nothing will be done even if the call fails (that is, the result of the bool type call is false). This is business logic demand. With a user-friendly syntax, however, if the call fails, the current transaction will also fail. For another example, the above _safeTransfer take a contract as successfully executed as long as the returndata length returned by the contract is zero (data.length == 0) or there is a bool value that can be parsed as True (abi.decode(data, (bool))); yet in the user-friendly syntax, only the latter case will be considered as successful execution.
If you cannot confirm in advance whether the called contract is safe, it is advised to use the call function to make a low-level call, and then carefully analyze its two return values according to the needs of the business logic to determine the state of the call before deciding how to respond.

Use Assembly to Construct Variable-length Arrays

Solidity has very limited support for variable-length arrays in memory. For example, it isn't like variable-length arrays in storage, which supports dynamic modification of its length with push and pop. The following functions cannot compile:
 function copyArr(uint[] calldata a) public pure returns (uint[] memory b) { for(uint i=0; i We must determine its length when creating a variable-length array. Modify the code this way and it will compile and execute:
 function copyArr(uint[] calldata a) public pure returns (uint[] memory b) { b = new uint[](a.length); for(uint i=0; i On the other hand, it's not like the variable-length array in calldata that supports slicing. The sliceArrMemory in the code below cannot compile, but sliceArrCalldata can:
 function sliceArrCalldata(uint[] calldata a) public pure returns (uint[] calldata b) { return a[:1]; } function sliceArrMemory(uint[] memory a) public pure returns (uint[] memory b) { return a[:1]; } 
But sometimes, we do hope to return a variable-length array of an exactly appropriate length. For example, in the getOrderList function of querying the order book, each member of the return value corresponds to an order (except the zeroth one). Can I apply for a large enough memory array in advance and then do slicing to fetch valid fragments? Not in Solidity. How about applying for a small memory array in advance and then dynamically increasing it? Solidity does not support it, either.
Therefore, the only way is to implement a function with a variable-length array as the return value in assembly, according to the ABI specification. This is how OneSwap finally implements the getOrderList function:
 // Get the orderbook's content, starting from id, to get no more than maxCount orders function getOrderList(bool isBuy, uint32 id, uint32 maxCount) external override view returns (uint[] memory) { if(id == 0) { if(isBuy) { id = uint32(_bookedStockAndMoneyAndFirstBuyID>>224); } else { id = uint32(_reserveStockAndMoneyAndFirstSellID>>224); } } uint[1<<22] storage orderbook; if(isBuy) { orderbook = _buyOrders; } else { orderbook = _sellOrders; } //record block height at the first entry uint order = (block.number<<24) | id; uint addrOrig; // start of returned data uint addrLen; // the slice's length is written at this address uint addrStart; // the address of the first entry of returned slice uint addrEnd; // ending address to write the next order uint count = 0; // the slice's length assembly { addrOrig := mload(0x40) // There is a “free memory pointer” at address 0x40 in memory mstore(addrOrig, 32) //the meaningful data start after offset 32 } addrLen = addrOrig + 32; addrStart = addrLen + 32; addrEnd = addrStart; while(count < maxCount) { assembly { mstore(addrEnd, order) //write the order } addrEnd += 32; count++; if(id == 0) {break;} order = orderbook[id]; require(order!=0, "OneSwap: INCONSISTENT_BOOK"); id = uint32(order&_MAX_ID); } assembly { mstore(addrLen, count) // record the returned slice's length let byteCount := sub(addrEnd, addrOrig) return(addrOrig, byteCount) } } 
We hope to construct a variable-length array conforming to the ABI specification as the return value, in EVM's memory. As we introduced before, a variable-length array is encoded into three parts: offset, number of members, and the content of the array. The return value here has only a variable-length array and no other parameters, so the offset is fixed at 32, which means that the second part (i.e. the number of members) starts at the 32nd byte.
Solidity will save the end position of all allocated memory space at the memory location of 0x40. The memory space higher than this location is not allocated, and is also the space available for constructing the returndata of the variable-length array. The first uint256 in this space is used to store the offset 32 ​​(mstore(addrOrig, 32)), the second uint256 in this space to store the number of members (mstore(addrLen, count)), and the following uint256 to store array members. Here, the variable addrEnd is used to point to the location where the next array member should be saved (mstore(addrEnd, order)). Every time a new array member is saved, its value is incremented by 32 (addrEnd += 32;).

Conclusion

In this article, we first introduce the Solidity ABI in brief. Then we describe some issues and tricks, and to understand and use them, you need to know the details of ABI.

CPChain AMA feedback release

CPChain AMA feedback release
https://preview.redd.it/udh6aohxp1x31.jpg?width=1920&format=pjpg&auto=webp&s=bb65e991d441bb86704c28ee9b6c81ad5eb94b67
  • Q1: The company raised money from investors promising to put value on CPC token while at this very moment the company is working on private chains for clients whereas promising no direct way to put the revenue in the CPC tokens itself and promising some "Market making" with that money. Will the company rethink to change its decision and put all the revenue in CPC tokens where both the investors and the company will be beneficial instead of only the company itself? Or is it giving up on the investors who have been with CPC through thick and thin..?
  • A1: Firstly, the reason why the foundation decided to put part of the resources to private chain development is not simply due to the consideration of team benefit. Actually, we do it simply because it is just one of the positive blockchain solutions that we are exploring for the entire industrial tech adoption. CPChain, similar to many other blockchain projects takes their public chain as “the one” to the industry. We believe that the public chain has more space for imagination and the public chain itself means the evolution from the web era. However, we can’t change the reality that the entire blockchain industry is still in its infancy. The industry, as well as the technology itself (especially public chains), is still some distance away from maturity. We have to admit that for most of the blockchain projects emphasizing business adoption, they face the universal problem regarding the long learning curve of their potential users and the dying situation for most of the Dapps. Only very few top projects have established a complete business line within a public-chain ecosystem. For the majority of public chain projects, they all started exploring business based on private chain/sidechain systems since there is a very strong demand (especially in China) for the private chain solutions. Our industry friends like Ontology and Vechain also started the BD in the private-chain solutions. Putting part of our resources into a private chain does not mean we only value our own interests. It is a complete misunderstanding. Actually, our main intention is to bring more realistic scenarios and users from the private chain into our public chain step by step. Secondly, for the question about how to reflect our achievement in the private chain to the value of CPC token price, we can see it from two perspectives.
1, The proportion of our investment in, as well as income out of the private chain project, is still low. Currently, we have not formed a complete business model for it yet. Please give time and space for it to grow.
  1. If we finally achieve breakthroughs in field of private chain solutions, it will provide very a strong price support for the token. The reason is straightforward: If we succeed, it will prove that the decision to expand the private chain business is the right one. It will also bring the project an excellent reputation and strong financial support. With revenue flowing in, we will have more resources in the fields of marketing, PR and price support.

  • Q2: CPC has had a lot of delays on nearly everything. Delays are normal and I appreciate it when it isn't sacrificing quality to make it rush. However recent activities state that with our investment, the whole resources wasn't used only for the main chain(update and maintenance), or wallet but also on hiring people and resources for some private chains where we won't directly reap the benefit from. With recent news, I find it difficult to have faith on CPC and one can realize it via Telegram that it's not only me rather way too many people are losing faith. Does CPC have any concern about that? How can an investor know/believe that the company is not making CPC tokens obsolete and going on a side track to take all the revenues? ​
  • A2: First of all, we would like to apologise for the many delays. We fully understand the frustration of the community. Building brand new, groundbreaking technology in a very volatile market is neither easy nor for the faint hearted. We started this venture to make our very well thought out but rather abstract vision a reality. Every decision we made since the beginning was made with the best intentions for both the community and CPChain. Most of the delays where due to the rapidly changing market conditions and the uncertainty that came with it. We will promise to improve ourselves. In a next big step we will open a brand new discussion platform, enabling the community members to participate in our decision-making process. Every CPChain investofollower will be able to drop their concerns and ideas. Secondly, we believe that the CPC price is ridiculously underestimated as we have one of the strongest research and academic teams in the DLT/IoT field. We’re convinced that both the public and private chains will ultimately generate income for everyone involved. As CPChain is the biggest stakeholder in the CPC token, it will also benefits the most from a strong CPC value. Hence, there is a big incentive for CPChain build a strong future for CPC.

  • Q3: The promise of the wallet has been delayed many times until it has been put on hold with the promise of an exchange. Then after giving a deadline on the date of the exchange, CPChain brought up another scandal with the private chain news. When can we expect the wallet and when can we expect to trade the non-ercs token?
  • A3: The foundation is working on the exchange swap procedure and the exchange listings. We’re actively talking with the Binance dex team. Also negotiations with one top exchange is still ongoing, our BD team is trying their best to make it happen as soon as possible. We will let the community know once we have any updates from our side. The wallet will still be released in November.

  • Q4: All (shocking) news to me and perhaps others, how are we supposed to know this if we are banned from the TG?
  • A4: We pride ourselves in being very tolerant but if you brought yourself in the a situation where you got banned from Telegram, you can follow the news on our website, reddit and twitter account.

  • Q5: The last news was an eye opener and explains a lot about the team past behavior. Cpchain is not a flagship product but something like a pet project at best and at worse the means to get funding for Iwurongs real business model where you do b2b r&d and getting revenue while using investors free money to fund this business. The very least you could do is link the private chains to cpchain or something like that. Some others suggestions ( use a percentage of revenue from BaaS to buyback some cpchain from open market and burn them or you could use cpc for private chain fees), Is there a possibility that you would reconsider your business model and at least consider your initial investors or were your intentions from the beginning to outright exploit us?
  • A5: As CPChain, we always take our investors and community members as one of our priorities. It’s not pleasant for anyone who’s financially involved to go through the current market conditions but we will NOT and will NEVER have any intentions to exploit any of our investors. Although, we admit that there are some misunderstandings due to communication problems between the company and the community. We will improve the communication and rebuild a trustworthy bridge between us. We started talks with some of our core investors to see if we can adapt our business model in such a way that it would greatly benefit the CPC value as both private and public chains grow over time.

  • Q6: Is there some indication of which business activities will actually use CPC?
  • A6: Yes, some of the activities we’re currently working on are a payment system for seamless EV charging; an in-vehicle data marketplace; an on-chain Freelancer platform, and many more to come...

  • Q7: In the Telegram, it is stated that CPChain is the lead developer for the VID Standard for MOBI. However, on the MOBI documentation for the VID Standard, CPC is listed as "VID Supporting Member" and not "Core Team". Can we get clarification if CPC is now a part of the Core Team leading the VID Standard, or if the MOBI documentation will be updated to include CPC in the Core group?
  • A7: Yes, CPChain is still part of the core development team. Dr. Ma and Dr. Zhao will pay a visit to the USA for the MOBI LA conference this month. We will have more articles related to their trip to in the next 10 days.

  • Q8: PDASH: Is PDASH working just on the Ethereum Blockchain? If yes can we expect that you change the configurations so that we can test the PDASH or is it completely compatible without configurations? I know there are many other things you are doing but on github there is nearly one year no activity in the PDASH project and PDASH was one of the main reasons I invested in CPC. Now there are other projects which are developing similar programs and it seems to me that you stopped to develop it and i get the feeling that we will be overtaken. I saw on the new road-plan that PDASH2.0 is even not a part of the road-plan anymore. Can you tell us how important is and will be PDASH for CPC in the future do you will further develop it, or did you realize that there are other more important things for the Network economy which have to be developed then PDASH (like VID)?
  • A8: PDASH it is definitely still in our long term schedule but we believe PDASH is a project that needs a very long technology & user incubation period. It cannot be fully developed by only us. We have discussed with our partners about the life cycle of PDASH and we all agree that the industrial deployment of PDASH will take a lot more time and resources. We have downgraded the priority of PDASH for now (Especially for 2019).

  • Q9: Can you publish/give a link where we can find the patents from Dr. Zhao about PDASH [if they are in English otherwise a translation] so that we can see what exactly was patented and for which regions they are valid?
  • A9: The patent application process is still ongoing so we cannot make the patents public yet.

  • Q10: I am beginning to understand how the National Driving Safety Center wants a private chain. As a top-down structure where data flows one way, this wouldn't necessitate the customer giving information. So although it was a great shock, this could be on a private chain. Because the customer can't choose which information is transparent as all driving circumstances are needed to evaluate safety. But do you foresee 2-way data streams where opt-in customer data is crucial such as smart cities and VID being on the public mainnet chain? Otherwise, the CPC token seems useless.
  • A10: Thank you, this is an excellent question regarding the utility side of CPChain token. You have understood it very well why some of the projects need a private chain rather than a public chain. For some companies a private chain is enough. They don’t need the “incentive” side of the blockchain because they’re only in need of the “recording” side of the chain. For most of the private chain business cases, several nodes in the system will make sure that there is very limited space for “cheating”. When recorded on a private chain, the data within the small cycle can be shared and are marked as “on-chain and real”. That’s sufficient and efficient. But are there cases where the public chain is needed? Yes, there are. For example, the idea of the in-vehicle data marketplace: In the near future when drivers start their car engines, they will read the following instruction on the main screen of the navigation system:” Are you willing to share your driving data today to receive X amount of CPC?” By simply pressing “Yes”, they can receive that X amount of CPC without any extra efforts. This is just one example but the basic idea of sharing your data for CPC has many applications.

  • Q11: What is your plan to share the revenue from the private chains to native token holders?
  • A11: We are having meetings and discussions with some main investors about the feasibility of this plan. Please give us some time because we want to work out a strong long term solution that benefits everyone involved for the years to come. More details will be released as soon as we can.

Telegram Q&A IV

Q1.)Will the website be updated when white paper 2.0 is released?
A1. Yes.
Q2.)What's is the status of Camp wallet R&D?
A2. We're focused on the R&D of the pools within the CAMP wallet, the pool page on CAMP will allow limited hub management to hub owners. We're testing and optimizing the porting of pools to a mobile version.
Q3.)When do you plan to resume selling hubs on Sharder mall?
A3. We looked at the stats on the previous 2 batches of hub sales and we don't think they're profitable. But after we gained close to 300 distributed nodes, we realized this is extremely important to the Sharder network. We're drafting a new sales plan and we'll be announcing it soon, we hope everyone within the community is willing to support this.
Q4.)Any details on Sharder Box? - How many will be sold? - 2020 is still release date? - Potential price of Box?
A4. The Box should be included with our new sales plan for the Sharder mall. The Box will play a different role compared to the Hubs within the Sharder network, hence it'll have a higher configuration costs. Please wait for an announcement regarding a quote on the Box.
Q5.)Do you plan to create more straight forward storage Dapp, similar to Dropbox. Where users can upload any Type of file that can be stored securely?
A5. Yes, we hope to have more storage Dapps built off the Sharder Chain. We have an experienced tech team but we hope to create a product that'll solve practical problems and has a clear business model for sustained development. We also welcome and encourage more people to develop based on the Sharder storage project to further enrich the blockchain ecology.
Q6.)SignEase shows: '4104105 - Data Stored and Validated' What kind of data are stored there by clients? Only contracts or other data?
A6. Contracts and other types of documents (i.e. attachments to contracts) are stored.
Q7.) At what stage do you plan to market SignEase and other future Dapps to potential clients outside of China?
A7. SignEase is only available for the China at the moment, we're definitely interested in expanding the platform to other countries but we hope to gain recognition and expand brand awareness within the Chinese domestic market first. If you are interested on expanding SignEase to other countries, please contact our team at: [[email protected]](mailto:[email protected]) . We will develop and release a separate version.
Q8.) Community would like to know more what's going on in them contain only information about development of Hub COS and SignEase client.
Could you add more information to monthly like:
- new hires / changes in team
- any ongoing marketing for SignEase, please mention it
- info about new SignEase clients
- what other things team worked on for last month
- any new plans, maybe some photo of how team is working from office
Community would like to know more what's going on in background than only COS and SignEase version updates and Medium monthly is best place to use it for such communication.
A8. Thank you for your interest towards Sharder and SignEase. There'll be a certain degree of changes to team members, the project could succeed or fail. As a team that's driven by technology and results, we place stronger emphasis on the results of our work rather than the progress.
Please note that SignEase is a separate independent project that's based on the Sharder Chain and is being operated by a professional team. We hope for their success as it'll also bring honor to the Sharder Chain. We also strive to get more info from the SignEase team to be shared within the Sharder monthly.
Q9.) In the next 3 months, what will the team be mainly focused on.?
A9. For the next 3 months, we'll be focused on releasing a new Sharder whitepaper and 2020 roadmap. We'll also be expanding our client base on SignEase.
Q10.)When we can see updated roadmap with realistic dates?
A10. See question 9.
Q11.)How does cooperation with ELA help to increase/scale the sharder blockchain and the SS token value and utility??
A11. This is a collaboration between SignEase and ELA. If the developments for SignEase is progressing well, then there'll be more demand for Sharder storage. Please note that we do not provide any investment advice. The cryptocurrency market is volatile, please make reasonable decisions with your investments.
Q12.) When will SS appear on China's Center for Information and Industry Development Approved crypto list Have you applied for this?
A12. We have not applied to the CCID yet.
Q13.) When will we see any utility for the Sharder token? What are the top two goals need to be accomplished for this? How will these 2 key points be accomplished by your team?
A13. Once the client base for SignEase have been expanded, we'll allow clients to pay for SignEase services via SS. When clients purchase SignEase services with fiat, a portion of it will also be converted to SS. When this goal is reached, SS will finally have utility and a real life case scenario.
Q14.) If my hub has a hardware failure in the future can i replace it?
A14. Yes, you can send the hub back to us and we'll repair it for free if it's under the warranty period. You'll be responsible for the costs of parts when the warranty period have expired.
Q15.) Bean cloud users doubled in a month last month. what lead to the increase in users? we can see the number is at 1652 presently, how many of these are individuals, how many are smes, how many are large scale enterprises, how many of these are government related departments? can we get any names of these?
A15. We'll do our best to request this data from the SignEase team, but we do not guarantee the accuracy of any provided data.
Q16.) Which govt (local or federal) depts. does Sharder have relationships with? The specific names of any local/national govt department that has a relationship with Sharder in any context? What is the goal of these relationships?
A16. Having relationships with the local government is useful but is not of great importance. The main point is whether the project can solve any practical issues and have a feasible business plan for profits.
Q17.)When can we expect an actual functioning main net that is being used by clients?
A17. We're able to deploy the mainnet at any time. The differences between the testnet and mainnet are: The various transactions within the testnet are complicated enough but the network is running optimally and is able to self-repair. We're confident the network will be even more simple and smooth after mainnet deployment.
Q18.)What are the challenges to launching ss main net: Time Other priorities Technical problems?
A18. See question 17.
Q19.)The original investors (zbj etc) Are they still supporting? What support do they provide if any?
A19. ZBJ is one of our partners and not an investor. We mutually share resources with our partners.
Q20.)regarding the Team in china.. What is their specific role and mission? What have they done in 2019 to accomplish this? What will they do in 2020 to accomplish this?
A20. The team in China is mostly responsible for technological R&D and the operations of a certain part of the project. The roadmap remains consistent. Please await for our new roadmap regarding plans for 2020.
Q21.)Can we get ssh access to our own hub ?
A21. Are you asking if you can move TSS into a DIY hub for mining? We do not support DIY hubs for mining at this time.
Q22.)are the new tokens still supported ERC20, if not how can we still save the tokens and how is it operates with our largest exchange Idex?
A22. The update for Ethereum 2.0 will be happening soon, we'll act accordingly to the situation and development of the project to determine whether to stay as ERC20 or to launch our own coin after mainnet launch.

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

______________________
______________________
______________________
Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.
:)

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

Nexus Business Development Q&A with Alex El-Nemer 30 August 2019

alexelmo [3:01 PM]
Hey @here Ill be around for the next hour or so to answer any questions you have about the UK Embassy and Business development. Alot of people have already sent questions privately so I will answer those first as I imagine many will be similar to others. Fire away!
belgianboy [3:02 PM]
Oke Alex that would be nice
David Walliams [3:02 PM]
How are you Alex?
alexelmo [3:03 PM]
Very well thanks @David Walliams
You?
David Walliams [3:03 PM]
Good thank you. How’s it be going on the business development side?
alexelmo [3:04 PM]
Very well. We've been working hard and its all starting to come together
Ok, heres the first question someone asked and my response
Q1 - What's the typical size of use cases that you talk to - startup/small/medium/large?
A1 - Over the past year we have talked to a large variety of businesses. From some of the largest businesses in the world, to companies looking to start a new business exclusively building on our blockchain technology:
Start ups: Researching which platform to build their new business on (a big decision). The Nexus APIs help here, they differentiate us from blockchains in which a specific coding language needs to be learnt (E.g. Ethereum’s Solidarity).
SMEs: looking into blockchain to see if it can provide operation efficiencies to suit their existing systems
Large: Large Fortune 500 companies - wishing to explore blockchain in a very specific area, or Proof of Concept / pilot deployments. (edited)
Q2 - Are you seeing more inquiries/leads/interest from one size category vs another?
A2 - Not particularly, we talk to as many interesting companies as possible and get a good reception across the board. Most of the companies which we have had discussions with are medium to large sized businesses, as they tend to have a greater capacity to explore innovative technologies such as blockchain. (edited)
CaptainMAD [3:07 PM]
Hi Alex, do Nexus have anything in the pipeline in regards to advertising (besides social media) once main net goes live?
David Walliams [3:08 PM]
wow new business who want to build on nexus exclusively sounds very cool
alexelmo [3:10 PM]
@CaptainMAD Social media will drive a large amount og our outreach. However we are also reaching our to our networks in the media to promote the tritium update and its benefit to the wider blockchain space. We are also exploring PR agency options (edited)
David Walliams [3:10 PM]
is nexus project still engaged with UK pr firm? I think you mentioned them long ago
Márcio [3:11 PM]
@alexelmo Could you tell us in quantitative terms how many projects currently intend to use NXS both publicly and privately?
CaptainMAD [3:12 PM]
@alexelmo Thanks
alexelmo [3:13 PM]
Q3 - What is a pitch deck? What format do you use? What sort of things are included in yours?
A3 - Our first meeting will typically be a presentation, which takes place via Google Hangouts and Slides. The initial Nexus intro presentation discusses the following characteristics of Nexus: speed, scalability, LISP, API integration, digital currency element, security.
These are discussed in comparison to the other major enterprise providers: Hyperledger, Ethereum, Quorum etc…
Márcio [3:14 PM]
@alexelmo In terms of the timeline, when will we actually start to have something built on NXS? How is the case with SoundVaudt? Is this our biggest and most important business case yet?
alexelmo [3:19 PM]
@Márcio Unfortunately we cannot discuss any potential deals, as it could be considered to be done with the intent to affect the price of NXS. If and when a use case is made public via a press release, then we will be able to discuss in detail with you all - assuming our contract with the use case permits.
Márcio [3:19 PM]
ok, thanks
belgianboy [3:24 PM]
How many nda's? How many compagnies talking with? Wich sector you focus thé most on? Wich sector asks Nexus thé most for help with thé blockchain. What are thé internal targets for business development? What's your personal best experience while doing this?
Is there much interest? While Nexus is still unknow, do compagnies know it? And know what thé 3dc can do and everything that is shown in thé zoomcalls?
How do you see thé Future for Nexus and its business development progress?
alexelmo [3:26 PM]
@Dawca_Mocy could you clarify the question a little?
@Márcio The possibility to build anything on live code, until now, has been limited by the main net activation. Currently Dino has built a number of demos in test net to showcase the potential of the Nexus blockchain use cases.
With regards to SoundVault, we still have a great working relationship with them, and continue to explore blockchain applications within the music industry.
Following the release of the main net, businesses will have the opportunity to build on Nexus, and check out the live running code. (edited)
David Walliams [3:29 PM]
I noticed there is a student focused use case demo - did the business development side reach out to any universities about the nexus project?
alexelmo [3:37 PM]
Q4 - How many nda's? How many companies talking with? Which sector you focus the most on? Which sector asks Nexus the most for help with the blockchain.
A4 - The first meeting is an introduction meeting, telling them about Nexus and see if there is interest from the other side. If there is interest, a follow up meeting will be arranged - for this follow up we typically get an NDA signed prior to the meeting. This is to protect the business’ idea, and also any of their sensitive information about say how their internal systems operate and also that they are looking into blockchain.
This NDA essentially means that Nexus cannot state in any medium, the name of the firm, or provide any detailed information on their business practices or details of the use case which they are exploring with us, to any other party. It also protects Nexus - we provide details on the 3DC for example, which is sensitive information which we do not want being shared with other blockchain providers.
As of today, we have signed approximately 50 NDAs with prospective businesses. Essentially this means that we have had a second/third meeting with 50+ different organisations. These organisations are typically based in either the UK or the US, with a few dotted around Europe. To provide a brief overview of the sectors in order of most frequently occurring: Supply chain/logistics tracking, music and IP, consulting, finance, education, insurance and ad-hock.
David Walliams [3:39 PM]
wow that's like 50 days worth of twitter announcements if they all work out :crossed_fingers:
ej [3:44 PM]
This is all very exciting news
belgianboy [3:44 PM]
What is ad-hock?
alexelmo [2 hours ago]
those not in that list
belgianboy [2 hours ago]
Ok thanks!
David Walliams [3:45 PM]
any universities alex?
alexelmo [2 hours ago]
There have been conversations in the education space (as per Q4) (edited)
belgianboy [3:46 PM]
Are those smalle compagnies or multi billion ones?
alexelmo [2 hours ago]
See above Question 1
belgianboy [2 hours ago]
Ok
alexelmo [3:47 PM]
Q5 - Is there much interest in Nexus? While Nexus is still unknown, do companies know it? And know what the 3dc can do and everything that is shown in the zoomcalls?
A5 - Yes, there is a great interest from those who truly understand blockchain technology.
Nexus is still growing in terms of its recognition, but we do see ourselves as a respected player within the enterprise space, much of this has come through positive word of mouth and Blockchain Working Group events here in the UK in which the major players have learned about us and heard of our unique features. We are building a strong reputation in the business community which is a very positive sign.
With regards to the 3DC - the technology is far beyond anything else we have come across, and many businesses agree with this statement. We can happily report that senior tech employees (CTOs) at large companies, have been greatly impressed with the quality and complex depth of Nexus’ technology.
ej [3:51 PM]
Thanks for all this, Alex
ej [3:52 PM]
Excellent work
paulscreen [3:52 PM]
Yup this is gold!!
Kendal Cormany [3:52 PM]
Good job
alexelmo [3:53 PM]
Q6 - What does an initial meeting typically go like? Do you pitch Nexus and its features first, or do you start by learning what the use case is trying to achieve and then talk about how Nexus can fit that?
A6 - The style of the first meeting really depends on the individual(s) whom the meeting is with and our prior knowledge of the company itself. If our contact at the organisation is a business focused individual (which is almost always the case given that our contacts are in this area) then we will discuss the following:
  1. Nexus history
  2. Our features - speed, scalability, LISP, API integration, digital currency element, security. These are discussed in comparison to the other major enterprise providers: Hyperledger, Ethereum, Quorum etc…
  3. How they could best utilise the technology to benefit their business as a whole (improved speed, transparency, efficiency, fraud reduction, regulatory reporting).
Following the above topics, a follow up meeting is arranged. A technical employee from the other company will usually attend this. Typically Colin or Dino will attend the meeting to discuss the Nexus technicals in much greater detail. The following topics are discussed:
  1. Technical comparisons with other blockchains (Why Nexus Contacts > normal Smart Contracts)
  2. How to integrate with existing systems (Nexus API > Complex Coding languages)
  3. Discussions around the best way to possibly start with the use case (run in parallel to existing systems, private vs public blockchain)
  4. Complex technical questions
If our contact at the business is technical (CTO for example) then Colin or Dino will typically attend the first meeting, alongside Myself or Brian, and this intro meeting will be more technically focused. In essence we adapt to whom the meeting is with.
Following meetings will be tailored to their specific company / requirements. We do like to be as tailored as possible early on though, to differentiate from the other providers whom generally look to just sell a fixed product. (edited)
pdogg147 [3:53 PM]
Yes thanks for providing some details @alexelmo
alexelmo [3:55 PM]
Q7 - What about subsequent meetings? Do you have a standard pitch presentation or are they tailored for different industries?
A7 - Follow up meetings depend on how the potential client wishes to progress. It could be in regards to any of the following:
  1. Follow up questions in regards to why Nexus over other providers (more in general questions or in regards to their specific solution)
  2. Further use case development discussion - best way to develop the use case to maximise associated benefits
  3. Disclosure of their internal systems and what they wish their use case to achieve for this business. An NDA is typically signed prior to the second/third meeting, as sensitive information such as this is disclosed, and needs to be protected.
A key point with Nexus that separates us from the larger players is that with us, we have the capability to tailor everything (right down to the Network Layer). Our meetings reflect this flexibility, so we never try and sell a set product. We will discuss with the business, see what they would like, and see how we can help.
alexelmo [4:01 PM]
Q8 - Are use cases going to be publicly announced and if so when?
A8 - If and when perspective use cases / partnerships have been finalised, and the deal allows public announcement, then we will 100% be releasing this as public information. This is our goal for all use cases, but it is down to the business if, when and how they release this information. We must respect that different businesses have different strategies and timelines. (edited)
Q9 - Do you do demo's of the Nexus blockchain in action? If so, who from the organisation does these?
A9 - Yes we do sometimes show demos of our Blockchain in action.
As Dino has built the Demos he is typically the team member who demonstrates a use case in action (how a supply chain would work on Nexus).
Colin has done some speed based demos (showing the speed of the Nexus Blockchain in terms of reads and writes per second).
ej [4:05 PM]
I am assuming you're not at liberty to disclose if any new usecases/partnerships were indeed finalized due to the reasons previously mentioned.
alexelmo [1 hour ago]
Unfortunately we cant currently.
ej [4:06 PM]
Understood
And thank you
Dawca_Mocy [4:08 PM]
@alexelmo
How will all this affect the price of nxs? Are we going down all the time? When will nxs be noticed? Can you tell something about investors whose portfolios are smaller by 95% today?
alexelmo [1 hour ago]
Please see question 9
David Walliams [4:10 PM]
I don't think he have crystal ball dawca
alexelmo [4:11 PM]
Unfortunately not @David Walliams......that would be helpful though! :joy:
Dawca_Mocy [4:16 PM]
@alexelmo Crystal ball. Hehe. Ok. Therefore, what price do you expect for nxs at the end of the year? I mean your opinion.
alexelmo [4:16 PM]
Q10 - Please discuss where we are in the process of letting NXS be purchased with fiat (if that is even being worked on) and the hopes of finally decoupling from BTC?
A10 - This is certainly a goal, although the main focus for us has been primarily on blockchain use cases recently. The reason for this focus on use cases is that as our adoption improves, we expect that our dependence on Bitcoin will reduce.
Generally it is the top ranked coins which are listed with liquid fiat pairs. As the adoption of the Nexus blockchain improves, we hope to increase up the ranks, and look to list with these fiat based exchanges. Currently, BC Bitcoin in the UK has the ability to exchange NXS with a number of fiat currencies and other cryptocurrencies.
David Walliams [4:19 PM]
anymore news on binance US? (edited)
alexelmo [4:22 PM]
Q11 - Are we going to be listed on BinanceUS?
A11 - I have been in conversations with Binance for a while regarding the developments at BinanceUS. We have worked hard to ensure we meet the requirements for a BinanceUS listing
Unfortunately a key requirement that we may fall short on is our trading volume. We expect that only the very highest volume coins will be initially listed as part of the BinanceUS launch.
We will keep you informed as this develops.
Q12 - How many companies are currently waiting for something specific before getting their feet wet?
A12 - The main thing we have been asked for by businesses over the past few months has been in regards to the Tritium main net release. Some of our businesses are waiting for the network to be live before progressing any further, so we are very excited for our potential use cases to see the release and have a deep dive into the live running code soon.
We would like to thank @dino for making blockchain demos in the private testnet environment which have really helped given the main net deployment release date has been delayed over the past few months.
B l a c k J a c k [4:33 PM]
What are some of the other industries we have looked to disrupt, but for which NDAs have not been signed or been followed up on?
alexelmo [4:38 PM]
Q13 - Have there been cases where Nexus has been preferred to other enterprise-focused blockchains such as Hyperledger, Corda, Ethereum?
A13 - In many cases, companies we have talked to have been greatly impressed with Nexus’ technology. Yes, in almost all cases the prospective client has said our technology is superior to that of the major providers, a feat which we are extremely proud of.
alexelmo [4:46 PM]
Q14 - Can we do anything to help with enterprise efforts?
A14 - We always welcome support and input from the community in regards to our business development efforts. I have had messages from a number of community members who have told us about companies looking into blockchain and have also had calls with individuals to discuss how it would be best to approach your personal contacts.
Feel free to reach out to me if you think you have a potential business in mind that would be a good fit, I’d be more than happy to jump on a call to discuss. Don’t be afraid to reach out to someone you know we are here to help if needed.
I think I've covered all the messages that have been sent to me privately and on here so Im going to call it a night. Thanks for your time guys.

Distributors; Manticora Capital, Bit Captial, Ubivelox, BlockPay and more to follow. Blockchain; NEM, UTrust, GGOX, Verime, Wanchain, Stella, Genaro Network. More to follow.
Burning of NPXS;
A quick summary of Pundi X token’s utility on each and every transaction: 1. A bit of it is burnt for every crypto related transaction that happens in through our XPOS. 2. The token is used to list other tokens in our XPOS, for example, QTUM paid us a sum of NPXS to be listed later in our XPOS, and this will include future coins that will be listed in our XPOS. 3. Loyalty programs are made & paid with NPXS. 4. Ads that run through our XPOS are also paid in NPXS. 5. Future products will be paid with NPXS. 6. Claim goods and services from merchants.
The XPOS is comprised of two parts, the consumer and merchant.
The Point of Sale device (XPOS);
For the merchants; 1. You get 1% extra as a fee. You can set it up from 0-3%, but we recommend 1% fee. 2. You can sell crypto again with that 1% fee. 3. You can sell the XPASS cards. 4. The POS can setup your inventory, loyalty programs, ads, and print smart receipts. 5. You can accept crypto, again the 1% fee. 6. You will be one of the first to change how the world uses crypto.
For the XPASS holders; 1. They can liquidate their crypto assets through our merchants, hassle free. 2. They get a special discount. 3. If you lose the XPASS black card, we are able to recover it (as long as you have the security card).
Case study of fees;
▪ 100% of Pundi X’s revenue that is generated through transactions on the XPOS will be removed permanently from our NPXS token circulation (and that's called token burn). This means that if Pundi X makes $1 of revenue from a transaction, they will take $1 worth of NPXS out of circulation permanently. NPXS tokens taken out of circulation will never be able to re-enter the circulation in any way as they will no longer exist.
▪ if the transaction is made in Pundi X tokens, we will take the tokens immediately out of the total supply. If the transaction is made in other tokens or fiat, we will use the proceeds to buyback NPXS, after which we will permanently remove the NPXS tokens from circulation and ensure they can never re-enter circulation.
▪ In case of a fiat to crypto transaction (including a payment with mastercard/visa) NPXS will be also burned.
▪ Case study 1: a user buys $1,000 worth of crypto from a merchant in a store using Pundi XPASS card. The total charge a user has to pay is $1,010; $1,000 for the crypto and $10 for the service fees. Of the $10 received, $6.50 is paid to the shop merchant for rendering this service. $3.50 is paid to Pundi X for providing XPOS (switch) and XPASS (Issuer) service.
Function X Blockchain – A game Changer:
https://i.redd.it/5ibzoexntpi21.jpg
The f(x) (short for Function X) blockchain under current test environments, each XPOS is an f(x) node; all data from the XPOS will be fully encrypted and stored in f(x) low level IPFS. Our IPFS is one that is specially designed for XPOS, f(x) and other smart devices. The f(x) public ledger will record all transactions, and the chain deploys sharding and PBFT. At Pundi X, we believe that open source is the way to go and to strengthen the blockchain community. We will gradually enable all of our operating system and f(x) chain’s code to be open source. It will be free for all Dapp software and hardware manufacturers to develop products for the f(x) ecosystem, hence achieving true decentralization. Let’s all work together and re-engineer a decentralized world.
10x for Speed; Visa can run 7,000–20,000 transactions-per-second (“TPS”). Any blockchain that offers small multiples of speed improvement is unlikely to displaced a tried-and-tested system like Visa. A 10X increase means 200,000K TPS has to be achieved. Our upcoming blockchain called Function X (fx for short), we have to make sure we are comparable if not faster, at 10X it is at least 200,000 TPS, not just on paper, but in real application. Sharding depends heavily on the availability of nodes. Confirmation processes increase by an order of magnitude when you increase node counts, we are already deploying the XPOS which will act as nodes.
10x for Scaling; Scalability in a restaurant means how fast can you serve your meals, the faster you can scale, the more business you can have. Therefore, companies like McDonald’s spend a lot of effort shortening the time between ordering and checkout to serve its customers. Scalability in blockchain is similar: it depends on the code (how fast can the burgers be flipped) and also nodes (how many cashiers can confirm the order). So whose code is the best? We will only know when proven. And what about nodes? The blockchain with the largest nodes will prevail. Currently Ethereum has the most nodes, but maybe not for long.
10x for Consensus; And what about nodes? The blockchain with the largest nodes will prevail. Currently Ethereum has the most nodes, but maybe not for long. With our minimum plan to roll out 100,000 XPOS in three years, we will be able to scale up transaction numbers significantly as the number of XPOS devices increases. Can we do much more than 200,000 TPS? Let’s analyze: Sharding is a process of dividing a global network into pieces of a local network. Each local network would then take charge of two-thirds consensus so that a particular transaction is verified in the local network and then broadcast to the global network.
Five Pillars of Function X Blockchain;
  1. Fx Operation System - (ROM) Android-modified blockchain-enabled operating system. Users can switch seamlessly between fx blockchain and regular everyday android mode.
  2. FXTP - (Web Protocol). Decentralized transmission protocol (P2P) and similar to https.
  3. Docker - Open Source platform for developers to build, ship, and run distributed applications (DApps).
  4. IPFS - Storage of various contents.
  5. Public Blockchain - A High performance and secure public blockchain.

The Blok-on-Blok (Smartphone);
The Blok-on-Blok (BOB), and the first true blockchain phone call, we demonstrated to thousands that we had a new protocol for communication that could take blockchain beyond the world of financial transfers. The BOB is powered by Function X OS which is based off the Android OS 9.0, so there is a backward compatibility with any Android apps. Blockchain-based calling and messaging can be toggled on and off on the phone operating system, which builds upon Android 9.0. On the blockchain mode, the services in the BOB can operate completely independently of centralized carriers. Users can route phone calls, messages, and data via blockchain nodes without the need for centralized service providers. The BOB is in fact the first mobile phone that can run completely on a decentralized ecosystem powering telephony, messaging, and data transmission. The BOB itself significantly expands the use of blockchain technology beyond financial transfers. Every BOB Phone is also a node on the network to contribute to the operation of the blockchain ecosystem. Content and connectivity are organized in a distributed, node-to-node manner. https://i.redd.it/ne3iufycqqi21.png
  • Every device in the Function X ecosystem will be a node and each will have its own address and private key, uniquely linked to their node names, not unlike traditional URL and IP addresses.
  • The OS can be overlayed to any existing Android devices without any compromises and compliment as a node to the function X blockchain.
  • Using a new DApp published on Function X, Zac hailed a New York City cabbie from midtown Manhattan to Central Park via a smart contract executed on Function X. The taxi order was both conducted and recorded on-chain and by-passing any ride-hailing service via BOB.
  • In the browser, you may browse the traditional Internet via HTTP or use the blockchain Internet via FXTP.
  • In f(x) OS, users are able to switch seamlessly between two modes. The blockchain mode allows a user to be connected to the blockchain - everything which you do in this mode like texting, calling, taking photos, browsing, etc. will be transmitted via the blockchain. In the traditional mode, it is like any other Android phone.
  • You can develop DApps for X Play Store and regular apps for Google Play Store. Note: Final design and specs are subject to change.
The FX blockchain: Giving data control back to users and creators. “What this all means is that data control can and must be given back to users,” said Pundi X Founder and CEO Zac Cheah.
“Telecommunications and Internet companies have derived tremendous value from controlling data. By decentralizing apps, we can put this data onto a smart contract, effectively giving control back to creators and to users”.
“Much of what we call peer-to-peer or ‘decentralized’ services continue to be built upon centralized networks. We are changing that,” added Cheah.
Mobile devices as nodes;
“Scalability in blockchain is derived from the number and geographic spread of nodes. It is clear how achieving a critical mass in terms of scale will require something with a high utility for people. The BOB thus has the potential to establish a large global pool of nodes,” said Pitt Huang, co-founder and CTO of Pundi X.
“And with Function X offering people the choice to be independent of a centralized communications network we’ve created a new use, a high and universal utility for blockchain. In turn, this will give life to a network large enough to support better scale, throughput, and new potential applications, plus true decentralization that has so far eluded blockchain.”

The F(x) Coin;
The f(x) ecosystem is fully decentralized. It’s designed and built to run autonomously in perpetuity without the reliance or supervision of any individual or organization. To support this autonomous structure, f(x) Coin which is the underlying ‘currency’ within the f(x) ecosystem has to be decentralized in terms of its distribution, allocation, control, circulation and the way it’s being generated.
https://i.redd.it/scikiwyj7qj21.jpg
Broadly, there are four main participants in the f(x) ecosystem, as shown above: • Consumer: Users enjoy the decentralized service provided by the f(x) ecosystem.
• Infrastructure Service Provider: Providing infrastructure service like the ones provided by mobile carrier, Amazon AWS but in a decentralized way.
• Developer: Building DApp upon f(x) network like Uber, AirBnb, Alibaba.
• Financial Service Provider: Providing liquidity of f(x) coin like NASDAQ, Morgan Stanley.
Infrastructure service provider, Developer and Financial service provider contribute the seamless operation and service shall generate the positive circulation, innovation and value flow to the f(x) ecosystem.
The value flow of the Function X ecosystem; • Infrastructure service provider can offer the service, such as Blockchain, FXTP, DDocker and IPFS to earn f(x) Coin.
• Developer can build applications upon f(x) OS to earn f(x) Coin and at the same time they need to pay for the infrastructure service.
• Consumer enjoys the service and pays for the service in f(x) Coin.
• Developer and infrastructure service provider shall earn f(x) Coin in return by providing their service and they can liquidate it through the financial service provider to earn some profit.
Together, these four participants will create a positive value flow. More service providers will enhance the quality of service and attract more consumers. More consumers will bring more value to the ecosystem by attracting more service providers,and creating f(x) Coin liquidity. Deep liquidity of f(x) Coin will attract more financial service providers to enhance the stability and quality of liquidity. This will attract more service providers to the ecosystem.
Utility of f(x) Coin;
f(x) Coin is the native ‘currency’ of the Function X blockchain and ecosystem. Services rendered in the ecosystem will be transacted with the f(x) Coin. Possible scenarios include: • For service providers: To get paid by developers, companies and consumers for providing storage nodes, DDocker and speeding up of network connections. The role of service providers will described in other sections.
• For consumers: To pay service fees for using DApps, nodes, network resources, storage solutions and other services within the f(x) ecosystem.
• For developers: To pay for services and resources rendered in the ecosystem such as smart contract creation, file storage (paid to IPFS service provider), code hosting (paid to DDocker service provider), advertisements (paid to other developers) and others. To get paid by the enterprises or organizations which require the developer’s service.
• For enterprises or organizations: To pay for service fees, developer fees and advertisements. Services provided to consumers will be charged and denominated in f(x) Coin.
• For phone and hardware manufacturers: To pay for the Function X Operating System customization. Note: we plan to only build a few thousands of the BOB flagship handsets and leave the rest to third-party manufacturers to build more using our operating system.
• For financial institutions: to receive payment for financial services rendered for the ecosystem.
• Many more future scenarios.
https://i.redd.it/r7626yle8qi21.png Hence f(x) Coin can be used as ‘currency’ for the below services, • In-app purchases • Blockchain calls • Smart contract creations • Transaction fees • Advertisements • Hosting fees
