From the birth of Bitcoin to the advent of smart contracts, to the sidechains and cross-chain platforms, the public chain has led almost every major technological innovation. However, from the TPS competition to the Dapp ecological competition to the beachfront DeFi, the road to public landing has never been smooth. At the same time, giants have entered the alliance chain, which is unstoppable.
Babbitt SheKnows specially planned the online thematic activities of “Dangerous Machine 2020 Public Chain Breakout”, including “Self-evolution, Public Chain Leading Technology Innovation”, and “Out of Void, Reality, Where Does the Application of Public Chain Breakthrough? "," Together with each other, alliance chain, public chain have the same goal? " 》 Three themed activities.

We invited Shuai Chu, founder of Quantum Chain, Charles Lu, Findora CEO, James CTO, ITO co-founder Terry, Conflux founder Long Fan, Yunxiang Blockchain CEO Huang Butian, Bystack leader Ma Qianli, and Xita Technology Director Kong Qingyang focused on the core issues of technology, applications, and the development of public and alliance chain paths, talked about the "crisis" and "opportunity" of public chains, and explored the path of integration between public and alliance chains.
At 8 pm on December 6, Kong Qingyang , marketing director of Xita Technology, Huang Butian , CEO of Yunxiang Blockchain, and Ma Qianli , director of Bystack , were interviewed by senior editor of Babbitt Wendy to discuss whether the public chain and the alliance chain have the same goal. The summary of the content is as follows:
Moderator: There must be a battle between the public chain and the alliance chain? What do you think of these two "blockchain" technologies?
Blockchain is a trust infrastructure, which makes data a key production factor and can promote the development of the digital economy on a larger scale. At the same time, it has changed the way assets are stored and traded. Regardless of the alliance chain or the public chain, the key is to bring commercial value, which is the essence .
Both are tools, and they should be used in any scene. There is no need to say which one, but only if it is suitable for a scene.
There are many points that can be combined. I recently worked on a TO B project, both of which are useful and complement each other with their advantages. Kong Qingyang:
Blockchain is not so much a new technology as it is a new form of organization. The blockchain creatively combines existing technologies such as cryptography, distributed storage, and consensus algorithms. In applications, the blockchain solves the problem of how multiple participants collaborate in the scene.
In this new organization, there are different scenarios depending on the number and breadth of participants. Some need to be placed in a public chain environment, such as DeFi, because it is for everyone and requires collaboration with global participants. However, it is limited to a limited number of participants, such as supply chain finance, clearing and settlement, and points transfer. In these application scenarios, the organization method requires participants to be more controllable, so use the alliance chain.
There is no good or bad difference between the two, because they are suitable for different scenarios.
Moderator: Is there a technical difference between the public chain and the alliance chain? Does the alliance chain draw heavily on public chain technology?
The technical difference between the two is mainly "the way to access the network". In 2016, we proposed that the technical integration of the alliance chain and the public chain is an inevitable trend in the development of the blockchain, and the two are developing through mutual reference and integration.
Moderator: What kind of scenarios are public chains and alliance chains suitable for?
The alliance chain is a local-wide collaboration. For example, everyone in the group forms an alliance to reach consensus on certain things.
The public chain is a large-scale collaboration. For example, your collaboration needs to be global, cross-domain, and cross-sectoral.
The two are overlapped. For example, the Internet court block chain judgment, based on the judicial alliance chain and the bitcoin public chain, can be used for Internet court evidence adoption.
However, there are some differences between the two. If the case is judged in China, a court-based alliance chain is sufficient. However, for transnational cases and overseas courts to judge, public chains like Bitcoin are more likely to be adopted.
Moderator: In specific applications, what kind of problems do public chains and alliance chains have?
The main problem of the alliance chain is that I can't find a very suitable industry combination point. The industrial side does not have a unified understanding of the blockchain, that is, everyone understands that the blockchain is different, and there are some misunderstandings about the understanding of the blockchain. A larger misunderstanding is that the data on the chain represents the truth, But in fact, the chain can only guarantee the consistency and invariability of the data, but it does not solve the problem that the data source is wrong.
Most of the time, we need to help the industry to find the joint point between the blockchain and the industry, but as a technology provider, our understanding of the industry is not enough, or we should find a joint point after the business personnel correctly understand the blockchain. This is a relatively large problem in my opinion of the alliance chain.
Then it is to understand the pain points of customers. The blockchain originated from the technology geek community. The practitioners mainly focus on technology development. However, to empower the entity and serve the public, it is necessary to understand its existing business logic and then transform it so that the public can The language of understanding is "translated".
In the traditional industry, there will be a position as an industry manager whose task is to analyze the domestic demand of the industry, and then combine it with the company's technology to create a solution. At present, such talents or positions are relatively lacking in the blockchain industry, and traditional sales and pre-sales personnel are very scarce in the blockchain industry.
Moderator: Do you think it is difficult for the public chain or the alliance chain to do it?
It's very difficult, but hard things are valuable.
There is a big dilemma in public and alliance chains. How to build an application ecology , especially the industrial blockchain, there are also problems such as breaking the original business model and coordinating the participation of multiple agents. There will be great uncertainty in the landing process . Moderator: Bystack ’s main multi-sided architecture is beginning to be effective in application scenarios such as government chain and garbage classification. What are the advantages of a main multi-sided architecture in specific applications?
There are two advantages.
At the technical level, the “impossible triangle” was broken through a new architecture.
At the application level, one main and multiple sides can make the blockchain closer to the scene. The real scene is very complicated. A large scene contains many small scenes. Each small scene has different requirements for the blockchain. The advantages of the main sidechain The problem lies in that each scenario can get a targeted solution.
Moderator: Recently, more and more large factories have begun to get involved in the alliance chain. They have funds, strength, connections, and demand. Are there any opportunities for startups?
A deep understanding of the industry's business scenarios is critical, as well as the ability to coordinate the participation of business entities in designing business governance models.
There are currently two types of alliance chain business.
One is the more mature financial and traceability applications. These applications are not friendly to start-ups, and there are many opponents. Moreover, large enterprises are currently setting up their own blockchain departments, with large teams of thousands, and they can do simple, conventional blockchain scenarios themselves.
The other category is innovation, such as trusted data exchange. If the blockchain team combines its own advantages and does some subdivided areas with not so many people, there will be more opportunities. Kong Qingyang:
I think there are opportunities for startups. There are many scenarios where blockchain can be combined, giants have advantages, and landing speed is very fast, but it is impossible to complete all scenarios and applications. This is the embodiment of the differentiated value of startups.
Another advantage is that they can adjust their direction very well. The giant needs to consider more, including the integration of its own huge system. In the blockchain industry, it may be easier for startups to find breakthroughs.
Moderator: Where is the profit model of the alliance chain?
There are four main aspects: product fees, access fees, transaction fees, and operation and maintenance fees.
First, blockchain-related hardware is easier to charge than software, such as blockchain servers, IoT hardware + blockchain, etc. Secondly, it is easier to charge extra-budget than in the budget, and extra-budget land is allocated for use. However, after the policy comes down, the budget for next year will be more generous.
The alliance chain allows companies with endorsement capabilities to join the alliance chain as a participant (node), even if they have no relationship with this alliance. In this model, participants, that is, nodes, can divide the revenue of the business party. The blockchain as a ledger guarantees the invariability and immutability of business data, which can make the revenue sharing more transparent. The node only endorses the invariance of the data, but does not endorse the legitimacy of the data.
Moderator: Starting with Libra and DC / EP, there have been more and more recent discussions on the differences in the development of China-US blockchains. So what advantages does China have in the development of the blockchain?
China's advantage in the development of the blockchain field is mainly due to the scale of industrial applications and policy guidance, which is more likely to form agglomeration effects.
Scene advantage . The Chinese government has a large number of scenes, and the Chinese government is determined to launch scene tests. General Secretary Xi Jinping mentioned 16 application directions in his speech on October 24. These references mean that there will be countless funds and manpower invested in this area.
Chinese society is more dynamic than the United States . From the perspective of a single market, China is more complex than the United States, and its development is relatively faster. Relatively speaking, Chinese companies are better suited to this rapidly changing market than American companies. Well, in the field of blockchain, it is developing very fast and changes a lot. In this process, Chinese companies are more likely to develop new models and technologies. At the same time, China's technical talent reserves are also abundant.
Moderator: Open source or patent, what do you think?
The purpose of open source is to facilitate the construction of ecology. The purpose of patents is to protect intellectual property rights. This is just a different path of business models.
The value of patents needs market inspection. We should focus on whether the combination of technology and business brings commercial value. This is the essential issue. Ma Qianli:
If you make a technology to build a barrier, apply for a patent. If you are doing this technology to build your own influence and want to become the industry standard, then open source . Companies that make both choices are not completely noble, and the goal is to maximize their own interests.
Blockchain as a decentralized technology is to ensure data consistency and immutability by spreading trust to different parties. From this perspective, open source is more important.
But I don't think that open source and patent are a two-choice issue. After the open source code, the company can still have its own patent. It is also necessary.
Moderator: Will the public and alliance chains merge in the future?
In 16 years, we thought that the integration of the alliance chain and the public chain technology was an inevitable trend. Then we promoted the VNT Chain, which creatively merges the distributed value transfer characteristics of the public chain and the commercial attributes of the alliance chain. Network), Galileo Network and Kepler Route.
The alliance chain is oriented to different business scenarios, and multi-dimensional data sources provide trusted data services for new businesses. The multi-chain architecture allows participants to choose different business chains based on their business needs. The public chain provides low-cost asset services for various asset authorizations, transactions, and transfers, and realizes the efficient transfer of digital assets. Cross-chain realizes the interconnection between the alliance ecosystem, and between the alliance ecosystem and the public chain ecosystem, and builds a connector for data exchange and asset exchange. Ma Qianli:
The public chain and the alliance chain are actually one direction, that is, decentralized or distributed, but the degree of decentralization is different.
In the future, the two will be understood and tooled by everyone. The public chain should be used, and the alliance chain should be used.
And we have been working hard to optimize the "one master and multiple sides" of the architecture so that the two can achieve a state of communion and symbiosis. Kong Qingyang:
In the future, the alliance chain may be one local area network, and the public chain will be the Internet connecting the local area networks. When you do your own business, you will complete it in your own alliance chain. Only when a wide range of consensus is needed, the final certificate will be completed in the public chain. In this direction, the public chain and the alliance chain can be integrated, just like the various layer2 solutions on the public chain.
