㈠ Blockchain and Distributed Credit

Guest: He Ping, Professor, Department of Finance, School of Economics and Management, Tsinghua University, Director of China Financial Research Center

Block Chains can address the shortcomings of centralized systems and establish decentralized or weakly centralized platforms based on emerging technological paradigms, promote innovations such as credit assessment, traceability, and consensus under new technological paradigms, and develop credit management based on new technological paradigms. platform, so this is the huge value that blockchain can potentially bring to the financial sector.

The distributed credit that blockchain may bring is divided into four links, one is distributed credit generation; the other is distributed credit transmission; the third is distributed credit evaluation; the fourth is distributed credit supervision.

Distributed credit generation uses the advantages of distributed accounting methods and data standardization to reshape the credit generation and recording process from the source to achieve "unforgeable" and "untamperable". The standardization of data can ensure the uniformity and comparability of all credit records. The participation of multiple nodes in verification can ensure the accuracy of the information in the records. Distributed storage greatly guarantees the security of information.

Distributed credit transfer is a technical business platform through blockchain technology, allowing each credit subject to transfer its own credit. The most important thing in credit transmission is to trace the source of the credit and whether it is reliable, leaving traces throughout the process. The credit of core enterprises can be transmitted downstream or upstream through the supply chain. In the future, more important credit transmission may come from more participants, which can be investors, consumers, financial institutions, core enterprises, and blockchain The chain can ensure that credit transmission in the supply chain will not decay.

Distributed credit assessment means that we can collect various types of data through blockchain technology, such as industry and commerce, litigation, taxation, etc. The source of these data is the subject of each credit assessment, and the credit needs of the subject are assessed. Evaluation, and can use blockchain technology to perform cross-validation and zero-knowledge proof on the premise of ensuring information security and privacy, and achieve trust consensus under the premise of privacy protection.

Distributed credit supervision uses blockchain technology to supervise, punish or reward credit subjects in all aspects of social life to achieve collective maintenance of credit. At the same time, joint punishment will be carried out. In the future, the scope of punishment, supervision and collective maintenance can be further expanded through blockchain technology.

Distributed credit is completely different from the traditional centralized credit system. It can alleviate the problem of difficult and expensive financing for small and medium-sized enterprises and promote the transformation of important economies into innovative economies. It helps to price credit risk more accurately, facilitates the allocation of credit risk, reduces credit risk through credit supervision, and controls the risk of the entire financial system. In the future, the centralized model and the blockchain distributed application model will inevitably be good at each other and complement each other. Blockchain distributed credit matchingThe supplement and improvement of the centralized system will play an important role in the improvement of China's financial system and even the international financial system.

㈡ How blockchain and zero-knowledge proof work in the credit system

Zero-knowledge proof in the blockchain plays a major role in privacy protection, and it plays an important role in the credit system Naturally, there is no exception, but where in the system and in what way does it work is a question worth thinking about and studying.

First, credit issues cannot rely entirely on technical reliability. Government authority is sufficient for some issues, such as household registration and identity information. There is no need for further questioning on these issues.

Second, the usage scenario of blockchain evidence storage should be the scenario where there is a long quantitative chain of evidence, such as monthly and annual summary based on flow statistics to ensure that the calculation process of summary is not Fraud. The flow details are in the upstream of the evidence chain, and the time is beforehand. If you falsify upstream, you can falsify months or years in advance. The planning ability of the attacker and the cost of falsification are much higher. To a certain extent, it is economically feasible to prevent fraud.

In fact, this involves the issue of closure of domain events on the chain mentioned above. For areas where it is almost impossible, or where there is no realistic possibility of complete closure in the foreseeable future, the degree of closure is a gray level issue. If you trace it upstream along the logical chain of events and upload them to a certain level, attacks will be impossible. When attackers' attacks become quite or extremely difficult, blockchain applications will generate value and do not require complete closure. In this way, the value field of the blockchain will break through the virtual currency and decentralized financial defi, which are completely closed to the chain. The system can be expanded. This logic is not limited to the credit system, but applies to the general logic of combining blockchain and fields. To give another example, whether the traceability system can achieve the anti-counterfeiting function depends on whether the depth of the traceability in the evidence chain is enough to cause the dilemma of the counterfeiter. Without examining this point, it is only a formal use of blockchain evidence. meaningless.

So we can almost get a theorem:

The value level of blockchain in domain applications is directly proportional to the traceability depth of the evidence chain.

Then the second question that follows is: tracing back along the chain of evidence, the further upstream, the closer to the privacy of the subject (citizen privacy or organizational business secrets). The solution to this problem is where zero-knowledge proofs come into play and how they work. The application value of many zero-knowledge proofs is ambiguous. Now it will become clear when we consider it in the context of the evidence chain:

1. Zero-knowledge proof is used to handle the quantitative evidence chain traceability process, and complete the traceability without revealing the plain text details of the upstream evidence chain. It not only plays the role of the blockchain in traceability along the evidence chain, Privacy is protected again.

2. For scenarios where traceability is not necessary, the evidence chain does not exist, and the role and significance of zero-knowledge proof are also unclear. For example, for general identity and household registration information, administrative authority should be considered credible and there is no need to trace it back. Note that the evidence chain mentioned here is not a causal relationship in the physical sense, but a value trade-off through system application goals.

To summarize:

1. Use blockchain technology to retain the upstream of the evidence chain. 2. The further upstream the evidence chain is, the closer it is to citizen privacy. Use zero-knowledge proof to protect privacy

1. Refer to zkledger of MIT Media Lab and use blockchain combined with zero-knowledge proof to deal with citizens and organizations Summary reporting issues of financial and taxation processes.

2. The technical problem that needs to be solved is that in the zkledger scenario, there are only a few large transactions of a few banks, and the amount of data is small. However, when used in individual citizen scenarios, the amount of data is huge and requires Find ways to resolve performance issues.

㈢ Why is blockchain technology conveying credit value?

Blockchain has the advantages of decentralization, non-tampering, trustworthiness, traceability, and network-wide accounting.
The most important thing about blockchain is that it solves the problem of intermediary credit. In the past, it was difficult for two people who did not know and trust each other to achieve collaboration, and they had to rely on a third party. For example, in payment behavior, any kind of transfer in the past required the existence of an institution such as a bank or Alipay. However, through blockchain technology, Bitcoin is the first time that humans have realized the transfer behavior that both parties can trust without the participation of any intermediary agency. Guarantees, loans, credit, risk control, equity, income, and ratings based on blockchain are all possible. The value Internet attributes of blockchain enable various economic activities to run more efficiently. Whether it is ordinary people in society or various economic people, it will be mapped to a "blockchain ID" to form a new moral system, evaluation standards, credit records, etc.

Is blockchain reliable?

With the development of the times, there are now many science and technologies used in people’s lives, and blockchain is used in a very wide range of applications. As an Internet technology, the purpose of blockchain is to verify the validity of information, so it has an anti-counterfeiting function. Blockchain is a combination of many data blocks in a chain structure in time order to maintain the reliability of the database. The application fields of blockchain are also relatively wide, and are often used in finance, the Internet, insurance, and some public welfare fields. Blockchain is divided into public and private, and its biggest feature isIt is highly transparent, decentralized and collectively maintained. Because it is used too widely, many people in daily life have questioned the blockchain and do not know whether it is reliable.

Generally speaking, blockchain technology is not a scam. It is reliable, but it also has certain disadvantages. Blockchain technology can have great benefits if applied in legal fields, but once it goes astray and is introduced into illegal fields, it will have very serious consequences.

㈤ Blockchain 100 - Zhou Kaiyu: Can blockchain credit investigation innovation break industry credit barriers

Mr. Zhou Kaiyu, CEO of Zhenxing Technology

At present, credit reporting has become a key part of the credit system and forms an important support in the operation of the modern financial system. There are certain difficulties and pain points in traditional credit reporting, but the decentralized and non-tamperable characteristics of blockchain will change in one fell swoop the issues of insufficient data privacy protection involved in the credit reporting process and consensus trust issues in the data sharing transaction process.

Mr. Zhou Kaiyu elaborated on the advantages of the combination of blockchain and credit reporting, and described the development status of the blockchain credit reporting industry at the legal level. At the same time, he expressed his views on the future development of Zhenxing Technology and the future direction of blockchain innovation.

Zhenxing Technology is positioned as a blockchain value ecological enterprise and is committed to building the next generation of trusted application service basic network based on blockchain. In June 2017, the company established a stable team structure and carried out related technical matters. From July to August, the first version of Zhenxing’s technical white paper was completed. At present, Zhenxing has implemented the first version of the system and has also started to provide related services in terms of blockchain-based identity verification. In the later stage, further development based on the second version of the credit evaluation system will be carried out.

In terms of ecological construction in the future, Mr. Zhou Kaiyu said that the blockchain credit industry has both value and opportunity. He hopes that industry partners with some high-quality resources on the B-side in the early stage can jointly expand services and eventually achieve A large number of users gather on the C-side, creating an ecological environment for high-credit preference transaction customers. In terms of the company's development plan, Zhenxing will break the inherent thinking of traditional blockchain anonymous verification, build a decentralized strong identity verification basic network, and integrate a trusted Internet service ecosystem.

The original intention of choosing a project that combines credit reporting with blockchain

“Choose blockchain to develop because it has a community-based approach that maintains the stability of the entire system. Consensus reward, consensus reward is a process of social value redistribution. In the process of social value redistribution, a value effect is formed in which the wool comes out of the pig and is paid by a third party. While achieving credit value, it can It is a means to encourage everyone to maintain high credit." Mr. Zhou Kaiyu said.

According to Mr. Zhou Kaiyu, in the traditional credit reporting process, the traditional centralized method is used to process data.It lies in the centralized platform, but it is difficult to prove the security of user data. The issue of personal privacy data has attracted attention from society, government, enterprises and other levels. Blockchain will form a combination with blockchain through the credit alliance.

At the same time, the Block Hall Chain can combine some personal security mechanisms to achieve comprehensive and strict protection of personal privacy data and complete credit reporting services with authorized attributes. Zhenxing’s credit reporting service combines the advantages of blockchain, using personal data and individuals themselves to provide diversified credit reporting services through data services.

What are the advantages of the combination of blockchain and credit reporting?

When it comes to the combination of blockchain and credit reporting, its main core lies in the data level, since credit reporting uses a large amount of user data. In a decentralized system like blockchain, data needs to be maintained jointly by everyone. It is difficult for anyone to change the data. This can clearly guarantee the security of user data. Any access to data requires user authorization. occur.

Regarding the current legal status of blockchain credit reporting, Mr. Zhou Kaiyu introduced, “In terms of credit reporting, the country has many management regulations to regulate the processing of customer data by enterprises. Blockchain + reporting In terms of information, it is a very good technical method." In his view, “Blockchain + credit reporting has become the only basic technology that can fully meet all requirements in terms of privacy protection when most technologies cannot meet the needs of credit reporting.”
< br />What are the options for future blockchain innovation directions?

Mr. Zhou Kaiyu said that the development of blockchain is still in an early stage, and there is huge room for future innovation in blockchain. Currently, we are optimistic about the direction of innovation, such as asset digitization. Asset digitization will be a relatively long process, and various applications will continue to emerge during development. In terms of technological innovation, blockchain still has a lot of room, and more attempts are being made in new directions of upgrading and balancing.

Zhenxing hopes to build a value exchange ecology with high performance value, and hopes that under its nourishment, everyone will be happy to maintain their personal credit, and everyone will be able to participate in the credit transaction process. gain from it. The future development of Wuxiaokai will be based on the core concept of maintaining high credibility and combating dishonest people.
