On April 19, 2019, the CITIC Notary Office issued the first block certificate in the country. This is the blockchain. Following the first instance of the Hangzhou Internet Court on June 28, 2018, the first blockchain deposit case was announced. The precedent of dealing with legal disputes by blockchain until September 2018, the Supreme People's Court issued the "Provisions of the Supreme People's Court on Several Issues in the Trial of Internet Court Cases", for the first time in the form of judicial interpretation to legally confirm the blockchain technology electronic deposit certificate. After the establishment of the Beijing and Guangzhou Internet Courts, they also used the blockchain depositing technology in the trial, once again in the legal field, and marked the official opening of the blockchain notary service era.
Speaking of blockchain technology, a series of professional terms such as distributed ledger, trusted timestamp, and hash value cannot be avoided, which may be strange to our people. But for washing, water army, forging notarization, forging WeChat screen capture, forging stamps, etc., everyone should be familiar with it.
So the question is, is blockchain technology related to these infringements? Can blockchain technology effectively prevent fraud in paper documents and electronic documents? What chemical reaction will happen to the blockchain and notary services?

At the scene of the first blockchain certificate issued in the country, the legal network reporter interviewed the professor of the Department of Finance of the School of Business of China University of Political Science and Law, the doctoral tutor, and the director of the Blockchain Financial Rule of Law Research Center. As soon as he came up, he told reporters that the technology itself is not mysterious. The most essential feature of the blockchain is to ensure the authenticity and unchangeability of the data. Then, the in-depth explanation of what the blockchain is and how it is combined with notarization is introduced. The application scene and the huge role played.
What happened to the blockchain? Why can't you tamper with?
Professor Hu explained the secret of the blockchain from the development of the book: the traditional Chinese bookkeeping is a single book, which is also a simple book. This method of accounting is very easy to fake, and it is easy to sit and sit, not Conducive to the development of business. In the 14th and 15th centuries, the Italians invented the double-entry bookkeeping method. Each act must be recorded in two accounts, which is common to all countries in the world and has become the legal accounting method in China. However, it is still prone to some problems, such as bribery and bribery in cash transactions.
Today, in the blockchain era, it is a distributed ledger, that is, the same thing N multiple people record at the same time. The blockchain cannot be falsified because of the distributed ledger it uses, decentralized, and without a center. The information uploaded to the chain is recorded on at least six different nodes, and each node records the same content. If you want to change, you have to change it all, and the existing technology can't do it. For example, in the past, the paper certificate can forge the notary's signature and forge the notarization stamp, but the blockchain notary can not be forged because the certificate is distributed and distributed to each node in the chain, which can theoretically reach a very large Quantity, each node has a complete record, like a piece of glass is broken, but every piece of broken glass retains all the complete memory, it is useless to change one of the broken glass.
Second, the blockchain ensures that each block is sequentially connected in sequence by a timestamp. The time stamp is equivalent to a time stamp, which makes each piece of data on the blockchain time-stamped. All the uplink data is distributed storage, time stamping, and the information that needs to be recorded after the millisecond generation is stored in the chain. It is worth noting that the actual information stored in the chain is not a hash value, which is equivalent to setting a password and solving the problem of data redundancy and storage security.
In a word, the reason why blockchain technology is so powerful is that the multi-book system is powerful, such as timestamps, plus its unique decentralization.
What happens to the blockchain technology when it encounters a notarization?
Notarization is an activity that proves the authenticity and legitimacy of civil legal acts, facts of legal significance and documents in accordance with legal procedures in accordance with the application of the parties. It can be said that the notarization is closely related to the daily life of the ordinary people. For example, to prove the authenticity of the party's entrusted behavior, the trustee can handle some affairs with a notarized power of attorney; for example, according to the application, some infringement of portrait rights and copyrights on the Internet. The act of notarization, the parties can directly sue to the court by virtue of the notarial certificate; for example, some people who want to study abroad need to be notarized for the academic qualifications and degree certificates obtained in the country, and then they can be used abroad.
However, with the development and growth of the digital economy, the notary industry faces the dual challenge of “new challenges of old business” and “old technologies of new demand”.
When talking about the first "blockchain notary certificate" issued by Beijing CITIC Notary Office in recent days, Professor Hu frequently praised it. "This blockchain notary has saved the party at least half a month, and the relevant departments only You need to collect the QR code on the public certificate of the scan code to verify and verify the authenticity of the certificate. You do not need to call or send a letter to verify it."
“Blockchain technology has a unique “genetic advantage” for solving the existing problems of notarization. The public certificate Hash encryption effectively guarantees the authenticity of the notarized documents; the time stamp and the non-tamperable features effectively ensure the cross in digital economic transactions. For example, the blockchain notarization has self-checking function, and once the notarial certificate is issued, it can be checked and checked at any time through the Internet. In the process of use, the real estate registration agency and other relevant units often need to go to the notary office. Verify the authenticity of the notarial certificate, from the influence of time, distance and other factors, reduce the time cost of the parties in the verification process and the workload of the relevant units. For example, with the extensive use of blockchain technology, the data on the chain is coming. The richer it is, it can break the information barriers between different departments and industries, and it also helps us to verify the information at the time of notarization, which can greatly improve the efficiency of the certification, and make the parties less or even wait. The blockchain issued by Beijing CITIC Notary Office The notarial certificate can be described as a further practice result of the combination of the notary industry and innovative technology. ""
In the face of some doubtful voices, for example, some netizens believe that the use of cryptography, the traditional Internet can also achieve the effect that the notarial certificate can not be falsified, why should we use blockchain technology? Professor Hu said, "The blockchain technology is not only the result of the electronic file, but also the process link, the user information, so it is more tamper-proof. Moreover, the blockchain technology is tamper-proof. Based on collective maintenance, unlike cryptography, after using blockchain technology, unless all nodes are changed, the change of the notary on the individual node is meaningless. And it is compared with the traditional notary. Compared with the addition of a two-dimensional code, the query is very convenient after the winding. The witness and the real estate agency can verify the contents of the notarial certificate by scanning the two-dimensional code on the paper certificate. Such a notarial certificate has no way for the notary office. Feel free to tamper with."
Finally, Professor Hu said that the blockchain is more and more in-depth to our legal system and legal community. I hope more legal colleagues will join the blockchain industry and meet the opportunities and challenges faced by blockchain technology applications. To jointly promote the development and improvement of the laws and regulations of this technology, so that technology can better serve our lives.
