Just as "science has no borders, but scientists have their own homeland", blockchain technology is open source, but developers have their own homeland.

The "domestic public chains" that emerged around 2017 were once highly anticipated and regarded as a Chinese force to counterbalance and surpass Ether. After 4 years, excluding Bitcoin, Ether is still the most dominant public chain in terms of ecology, technology and market capitalization, but most domestic public chains have gradually changed from being the challenger to accompanying and now lagging behind significantly.

The setback is temporary, and the domestic public chains have not given up the market voluntarily.

At the BSN Global Partner Conference, the founders of domestic public chains such as NEO, Qtum, IRISnet and Nervos took the stage and shared their thoughts on blockchain.

NFT helps the development of real economy

Cao Heng is the founder of Boundary Intelligence and also the founder of public chain IRISnet. She shared the practice of NFT technology in helping the real economy.

Cao Heng said that the blockchain technology on which NFT is based can be naturally used for asset validation and trusted exchange, which in turn supports the recording and processing of multi-dimensional data objects with complex attributes on the chain.

With such a technical foundation, it can support real business activities. For example, in supply chain finance, NFT can do a very good modeling and description of accounts receivable. In carbon neutral, an epochal proposition, NFT can support the credible collection of carbon data, the accuracy of carbon emission rights and sources, the accuracy of carbon sink accounting, and the openness and fairness of rules, which have very important commercial value. In cross-border trade, NFT can be used to model digital warehouse receipts, bills of lading, letters of credit, and lading rights.

Bullish on chips and privacy computing

Shuai Chu, the founder of Quantum Chain, is very optimistic about the opportunities of blockchain in chip and privacy computing segmentation track.

In the chip field, like Intel and AMD, because of the issue of domestic independent control, government agencies, government institutions or financial systems do not tend to go with them, but will instead choose the all-in-one machines or chips produced by domestic independent manufacturers.

Without the scene driven, it is difficult to make money in the market, there is no ability to feed the R & D, and it is not possible to iterate faster than others. After the commercial layout in this field forms a certain scale, it can feed the R&D ecology, and then combine the services of privacy computing and blockchain, which is instead a very good opportunity for future commercial development.

Manageable blockchain

The public chain ecology is developing very vigorously, while the alliance chain and private chain comply with the laws and regulations of many places, as well as the general public's inner perceived good and correct standards. How can the advantages of both be better combined?

Hongfei Da, the founder of Distributed Technologies NEO and also the founder of NEO, shares his thoughts on the manageability of blockchain.

In the past few months, Hongfei Da has conceived a blockchain that is more open and at the same time has some manageability.

Such a blockchain has the following characteristics:

1. Censorable, with a way to filter, isolate and block harmful information on the chain.

2. Editable, it is a misunderstanding to emphasize the non-tamperability of the blockchain. The word "tamper" means unreasonable modification, not that the historical information cannot be edited more formally.

3. Authorizable, able to authorize different capabilities for the roles on the blockchain, including consensus nodes, propagation nodes, regulatory nodes, etc.

4. Governable, including the upgrade of the blockchain, the adjustment of the operating mechanism and parameters of the blockchain and other governable capabilities embedded in the blockchain manageability. According to the above features, Dahongfei team designed a two-layer ledger of manageable blockchain mechanism. The lower layer is the structure of DAG, a directed acyclic graph, which is not considered a pure blockchain structure, but anyone can participate in the bookkeeping and has high concurrency. On top of this network, a regulatory-compatible consensus layer that requires permission can be overlaid, which is itself a DAG. Such a consensus layer can select the DAG path below and eventually drop the compliant information on top of the blockchain. The upper layer has a consensus layer similar to a federated chain, and this consensus layer can use BFT and also an authoritative mechanism to do the final compliance review and confirmation of the lower ledger. With such a combination, it is possible to achieve high concurrency and openness, while being able to do manageability of the information on the chain.

Making the blockchain experience silky smooth

Guonin Lu, co-founder of Nervos Foundation, shared his exploration of what public chains do in terms of Internet experience.

Guoning Lu had personally tried to let his father experience the blockchain applications of the day::

"I asked my father to create a wallet, and a note word was formed when creating the wallet, and I was impressed that I asked my father to write down the word at that time, and my father looked at the 12 note words and found that they were all in English, and he said I couldn't remember these 12 words. I said it's okay, you can copy down these 12 words and save them in a safe place. So my father copied them down and thought about where they would be safest. And there is money on this note, so if one day you don't have the means or you are no longer there, whoever has the note can take the account behind the note. My father solemnly gave me a piece of paper with 12 words copied on it. Looking back, it feels like delivering a will." And that's just registering the wallet, which hasn't involved more complex applications enough to give the average user a headache.

In terms of how the mature Internet operating experience can be introduced to the blockchain, Nervos realizes the connection to various protocols on the Internet such as hypertext protocol, email protocol, SMS protocol, etc. through wallets, mobile terminals and browsers, and then realizes the protocol of the Internet is connected to the blockchain protocol, and the blockchain can directly interact with the Internet to achieve the interoperability of protocols, and the interoperability of protocols brings about the value of The interoperability of protocols brings about the flow of value and better coordination and organization of resources.
