As far as the action method and path of the chain reform are concerned, there is no more mature method. It is still necessary to explore the advantages and disadvantages of the Internet, digital economy, currency reform, ticket reform, and work ticket reform as references. However, there is an absolute consensus, that is, to empower the real economy and the digital economy under the premise of compliance.

The full name of the public chain is the "public chain." The public chain is open to everyone. When developing a public chain, users can access the network and blocks anonymously without registration and authorization. Anyone can freely join and exit the network, and participate in accounting and transaction.
Contrary to the public chain, a "private chain" is a blockchain that is fully controlled by an organization or institution and whose data read permissions are regulated by the organization. The "consortium chain" is between the public chain and the "private chain", and is suitable for B2B transactions such as transactions and settlements between different entities. The user groups mainly include banks, insurance, securities, business associations, group companies, upstream and downstream companies, etc. . For example, China UnionPay and China Everbright Bank jointly used the alliance chain platform to build a multi-center trusted POS electronic purchase order system.
The public chain is a decentralized blockchain in the true and complete sense. It guarantees the security and immutability of transactions through cryptography (asymmetric encryption) algorithms, and establishes mutual trust in an unfamiliar network (non-secure) environment And consensus mechanism. In the public chain, consensus mechanisms are generally Proof of Work (POW) and Proof of Rights (POS).
Because everyone can participate in the public chain, the feature that it does not require authorization is also called a non-permissioned chain, that is, it can participate in all network activities without verifying the identity. At present, Bitcoin, Ethereum, Hyperledger, most altcoins, and smart contracts are built on public chains. The ancestor of public chains is the Bitcoin blockchain.
The public chain is suitable for application scenarios such as digital currency, e-commerce, Internet finance, and intellectual property.
Two major advantages of public chains:
1. The public chain can protect the rights of users from the influence of program developers
The developer of the program in the public chain has no right to interfere with users, so the public chain can protect the rights and interests of users who use the program. Why are program developers willing to give up their rights. However, more avant-garde economic analysis points out: First, if you choose to do something that others cannot do, others are more likely to trust you because they do not have sufficient confidence and courage to do what they cannot do. Second, if you are being intimidated by others to do something you don't want to do, you can say "even if you want, but you don't have the ability to do it" as a bargaining chip when you negotiate. This is the biggest advantage of the public chain.
2. Public chains can produce network effects
The public chain is open and may be used by many external users and produce a certain degree of network effect. For example, if A wants to sell a domain name to B, there is a risk problem that needs to be solved: if A sells the domain name first, but B may not pay; or B has paid, but A still Did not sell the domain name, but need to pay a handling fee of 3-6 percent. If we can build a domain name system on the blockchain, and use the currency of this blockchain, we can establish a smart contract with a cost less than zero: A sells a domain name to the domain name system, and the user who pays the fee first can get the domain name , But it is faster and more efficient to build the same shared chain database from different industries and different assets.
Since the industry is empowered through blockchain ideas and technology applications, it must be consistent with national strategies, industrial policies, and legal compliance in order to have the basic guarantee to take root and obtain support and help from the whole society. At the same time, a broad community consensus is needed to promote the formation of a bottom-up, external-to-internal economic transformation model. It also needs to stand on the global structure to further optimize and integrate. In the face of such a huge chain reform plan, media support is especially needed to jointly promote and encourage various organizations, alliances, associations, groups, local governments, and industrial parks to set off a "chain reform" wave. In addition to the media, training and education are also needed. With the popularization and deepening of education in the chain reform, the industrialization of the blockchain can be achieved, and the benign transformation and development of the social economy can be realized.
