Summary of PCHAIN AMA on 04/06/2019

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 a “Hub Zone“ or the Structure of PCHAIN with Main and Child Chain better? And why?

Feng: No Hub Zone. As main chain and child child shared the same native PI. And the cross chain tx need to be confirmed both in main chain and child chain.

Q2:You mentioned recently that the mainnet was stable with a 1–2s per block and instant finality with ~80 miner nodes! Could you share with us PCHAIN finality formula and what you have achieved (developed) to improve it, such as node communications.

Feng: 1–2s is in normal case. As our PDBFT gets only 1 leader in one-round, we can got instant finality. The magic is the communication msg is greated compressed from N² to N. That means our consensus will be much more stable when the global network is unstable. And this has been verified in last two weeks. When the global network is unstable. You can observe PCHAIN is becoming slow. While some other public chain deaded (no block generation)

Q3: Will Qiang Sheng Smart-e be running validator nodes on its Commercial Child Chain? How many? With staking?

Feng: Qiang Sheng Smart-e is running Commercial Child Chain and generated over 500k blocks in there child chain. The biz modle of commercial child chain is not finalized. The general idea is the commercial child chain will pay for the tx and 80% will be rewarded to validators.

Q4: How much does it cost to deploy a contract on PCHAIN? Average transaction fee for a transaction?

Feng: It’s very cheap now. You can almost ignore that cost.

Q5: Could you give more details about the characteristics of the BEP PI token: supply (total and origin), pricing, listings, functions, etc?

Feng: we will announce more details. Generally, the total amount of PI is still fixed and not changed. We will support bi-direction swap. If you need PCHAIN functions and staking you need native PI. If you want to trade or call some functions in binance chain, you can swap your native PI to BEP2.PI.

Q6: When and how PCHAIN could be huge blockchain service platform?

Feng: More and more commercial child chains will be deployed. And you can expect 100 million level tx and 10 million level users within 1–2 years. In the mean time, more smart contracts will be deployed in PCHAIN.

Q7: 10 million users? I think even Ethereum don’t have that many users

Feng: You can wait and see. That’s why commercial child chain is very important. In real commercial use cases 10 million is not a big number. You can even expect 100 million users if a commercial child chain success.

Q8: Are commercial organizations in China allowed to store personal data abroad? (because blockchain nodes are located worldwide)

Feng: We have our special solution on privacy. And we will announce collaboration with some MPC (Multi-Party Computation) partner soon.

Q9: Can we expect any new commercial childchain announcements by this month?

Feng: Yes. You will see some great news in this month.

Q10:Did you initiate Coinsuper&PCHAIN promotion or thats a requirement?

Feng: We initiate that promotion together. As some one of you may not know that Coinsuper is the №1 exchanges in HK with government license.

Q11: From one of my friends, I noticed that Alipay is organizing a hackathon activity to attract developers to their ecosystem alliance chain. So, there is a trend that traditional internet giants are entering this field. How can we compete them in such a condition since the tradition internet giants have sufficient capital, intelligence, and the most important thing, they have a bunch of business-level clients and usage scenario?

Feng: Yes. They really have advantage in centralized environment. While their gene determined everything. It’s a decentralized battle.

Q12:How many tokens does a company need to lock for a commercial child chain… or does it vary… or is there a link to show more on this?

Feng: It depends on their biz model. In some cases, they will pay our service fee. In some cases, we will share revenue.

Q13: So do you mean PCHAIN focus more on average people use case instead of commercial level scenario?

Feng: commercial level scenario doesn’t mean centralized. In the contrary, more and more scenario are decentralized business.

Q14: Do you estimate nearly all child chain will made and use in China?

Feng: No. We collaborate globally.
