Summary of PCHAIN AMA on 01.29.2019

We have finished the AMA with Dr Feng Cao on the telegram. Thank you for your participation and support. The following is the summary of the AMA.

Q1: Is PCHAIN vulnerable to the “fake Stake” attacks which have been witnessed recently on chain-based Proof-of-Stake cryptocurrencies?

Feng: No, we won’t have this vulnerable to the “fake Stake” problem as our system is not based on the UTXOs model, we are based on account model. Another important factor is that our algorithms — PDBFT algorithms is instant finality instead of the longest chain.UTXOs and longest chain are the two factors which caused the vulnerability of the “fake Stake”. As we avoid these two factors in our fundamental design,we will not have this problem.

Q2: Could we have more information on how you will use Docker’ technology?

Feng: Currently we are using the Docker tech for internally test. After the mainnet launch,we will open source of the Docker’s version when it becomes stable.

Q3: How are you planning to create a bridge with non-crypto companies? How much progress have on you made with OneLedger on this front already?

Feng: We believe that PCHAIN technology can be adopted both of the crypto companies and non-crypto companies. Most of the non-crypto companies are very interested in adopting their off-chain business and existing business to on-chain business and use blockchain technology to expand their existing business. As an advanced blockchain technology, PCHAIN — cross chain tech can help them to complement their tasks and goals easily at the first stage.

As time going on, they will definitely have more requirement on whole public crypto technology. And then they are able to seamless integrate their existing child chain to the public chain via PCHAIN native multi-chain system.

OneLedger is our partner and we are in the discussion in this direction. And we are on the same understanding that we are working together to try to make our blockchain interoperable.

Q4: Could we imagine future partnerships with traditional tech integrators such as Accenture, Infosys, Cognizant, HP, Tata Consultino, Deloitte, etc.?

Feng: Yes, traditional technology integrations are definitely our another direction for our partnerships. As you know we have too many directions to follow, even though theoretically we can do that,we still need the right time and the right project to start this partnership.

Q5: More details on WanChain joining PCTA? Impact on PCTA and PCHAIN, could they provide BTC cross-chain?

Feng: Yes, recently PCTA attracts a lot of attention and it becomes a very important alliance of public chains both in China and globally. That’s the reason to attract WanChain to join PCTA. For both PCTA and PCHAIN, we have some different partners who is working on BTC cross chain. And BTC cross chain is definitely a direction for PCHAIN cross chain technology in future.

Q6: How are you planning to improve your GitHub documentation? Can we suggest new formats such as Video tutorials? Feng: Sure, definitely. Currently beside the internal test and further bugs fixing on our codes, one of our most important effort is working on GitHub documentation. You can notice that we have already done a lot of updates and we will continue doing this kind of doc-working in incoming 2–3 months.

Video tutorial is a very good suggestion and it takes a lot of extra work. Based on our extremely tight schedule for the mainnet launch, we need to do everything step by step to achieve the main goals. This is a definitely good suggestion and we will do more tutorials later in video format.

Q7: How can we help you with Community engagement, starting with GitHub?

Feng: We believe that we will have more development contributors from our community, that is why we set up the developer webpage http://developer.pchain.org/ which linked directly on our website.And we would like to encourage more community members who are not only just working on the network or business, but also working on the code and document directly. And everyone is welcomed to initial new PIP (PCHAIN Improvement Plan) in PCHAIN developer community. Based on the contribution and importunacies of proposals,you will be rewarded the PCHAIN tokens as the prize.

Q8: What do you think about having automatic provisioning of the PCHAIN nodes shared by the community while waiting for a better documentation?

Feng: Yes, currently we share the PCHAIN nodes by documents. And we are working internally for providing a monitoring webpage to update the nodes info automatically in the PCHAIN network.

Q9: Your opinion on the new ticker name PI?

Feng: From my point of view, “PI” is a very good ticker, which is simple and has the connection with our previous ticker PAI. Meanwhile, PCHAIN is a team who always respect our community’s feedback and takes them extremely seriously. All of you can see “PI” is the best voted unique ticker in our ticker polls. Thanks for the participating and effort. As the result is coming from you, we believe it is coming from us as well because we are together to bring PCHAIN for shaping the future.

Q10: Jeff, you said that smart data is the trend of 2019, can you tell us more about the architecture, what it will be like and what tasks it will solve?

Feng: In fact, Smart Data is an important direction which I proposed 2018. Beside Smart Data,we also proposed multi-chain, cross chain and sharding in 2018. And all these 3 has been already proved as main stream technologies in 2018. After discussion with several public chain influencers and communities, we observed that Smart Data will become more and more important in 2019. The reason is quite simple, no matter how information technology developed, the data is always the centre from the very beginning till now.

Previously we look at the blockchain technology from the consensus point of view, and decentralized point of view. But we didn’t put much effort or analyse the data level. The data inside of blockchain which you can consider as Smart Data as well, will be more and more important as more and more data will be stored inside of blockchain. That’s the key idea of Smart Data.

Q11: Could you tell us more about the standard of W3C, what tasks it will solve and how?

Feng: Ok. You may be aware of that W3C has published blochchain as one of research standard direction in this year. Currently we are still in the discussion with W3C to propose the smart data format into the standard of W3C, and that is the direction that we want to move forward. A good news is that we are already in the IEEE data format community, we have been putting a lot of effort on smart data format in IEEE and we may finish this part first then we move forward to W3C standard.

Q12: Is there any difference between a validator node and super node?

Feng: Different word on the same thing.

Q13: How many enterprises will use PCHAIN platform this year?

Feng: Currently, we are carefully selecting the industry instead of the number of enterprises. There will be tens or hundreds of enterprises in PCHAIN commercial child chain if we found a promising industry. Currently, it went very well. We got more and more requirement from various company. And many of them are listed company.

Q14: When first Taxi DAPP starting?

Feng: Currently,we are in architecture design phrase. It looks very promising.

Q15: Will be a Hardware Wallet connection be possible to integrate (Ledger Nano S) after the Mainnet.

Feng: We are negotiating with different wallet provider. We hope to get the support from hardware wallet as well.

Q16: Hey Jeff, thank you so much for frequently interacting with community. I am so pleased with efforts of PCHAIN. I just want to know if the Team is planning any fund or support for dapps as they will help spread PI blockchain. Also is some percentage allocated for dapp ideas and are we taking any proposals?

Feng: Yes. Very good suggestion. Definitely, we are planning funds to support dapps on PCHAIN and develop our PCHAIN ecosystem.

Q17: Ethereum is the largest platform. Soon expected to fork Constantinople. What competitive advantages PCHAIN have? Companies will make a choice. What is the most important competitive advantage? PCHAIN > Ether?

Feng: Multichain+ PDBFT+ Cross Chain+ Smart Data. For time being,I only elaborate Multichain. There is a new paper named “Monoxide: Scale Out Blockchain with Asynchronized Consensus Zones” which is accepted in NSDI 2019 a top conference.

Theoretically, Multichain is a kind of Asynchronized Consensus Zones. And this paper proved the high scalability of PCHAIN.

Q18: There is already a list of large companies that are waiting for the PCHAIN mainnet to start using it?

Feng: Yes. Many company are very interested in PCHAIN tech and would like to try it.

Q19: This companies will used PI tokens?

Feng: Yes. If they want to use smart contract service in PCHAIN they need PI.

Q20: What features (PDBFT 2.0, BCH cross-chain, smart data?) will be implemented and available to developers in the mainnet version of the network in the March?

Feng: In mainnet launch in March,we will include multichain and PDBFT2.0 as defined in our whitepaper. We will have crosschain and smart data in mainnet in 2019 dev plan.

Q21: How many PI will be charged from them? And what will happen with this PI coins? You will burn them? Or some % of them.

Feng: It can be used as a stake or mining rewarding for new childchains and feedback to community.

Q22: Hi Jeff, my question is does PAI have enough funds to operate and work on PCHAIN for coming years?

Feng: Yes. We have enough funds to support PCHAIN development for years.
