Blockchain generation process

1.

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

2. Blockchain is a distributed database system participated by nodes. Its characteristics are unchangeable and unforgeable. We can also understand it as an account book system. It is an important concept of bitcoin. A of the complete bitcoin blockchain records every transaction. Through this information, we can find the value of every address at any point in history

blockchain is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is connected to the current block from the original block to form a blockchain.

3. From the perspective of data, blockchain is a kind of distributed database or distributed shared general ledger. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data. From the perspective of effect, blockchain can generate a set of time sequence, tamper proof and trustworthy database
blockchain has four core technologies. The first one is block + chain, which is the most core and basic technology in blockchain. The second core technology is distributed structure. The ingenious design of blockchain structure is to let every node participating in data transaction record and store all data. The third core technology is asymmetric encryption algorithm, and the fourth core technology is script, which can be understood as a programmable smart contract.

Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:

1; Hash chain & quot There are several nodes participating in the system operation (distributed)

3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm

since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications

5. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

6. The development of blockchain can be divided into three stages. Melanie Swann, founder of blockchain Science Research Institute, in her book blockchain: blueprint and guide to new economy, according to the application and development of blockchain, it can be divided into three stages: blockchain 1.0, 2.0 and 3.0< br /> 
I. blockchain 1.0 cryptocurrency era (2008-2013)
&
in 2008, Nakamoto first proposed the concepts of bitcoin and blockchain, and then in January 2009, the first blockchain came out. At this stage, people pay more attention to the transaction of cryptocurrency, and blockchain is only used as the underlying technology to act as a "public account book"< br /> 
2. Blockchain 2.0 smart contract era (2014-2017)
&
in 2014, & quot; Blockchain 2.0 "has become the pronoun of decentralized blockchain database. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute the smart contract on the blockchain, and will be rewarded automatically after the execution. Because this transaction process does not need any intermediary, so people's privacy has been greatly protected< br /> 
III. blockchain 3.0 large scale application era (2018 -)
&
at this stage, people begin to build a completely decentralized data network, and the application of blockchain technology is no longer limited to the economic field, but expanded to the fields of art, law, real estate, hospital, human resources and so on.

7. If we simplify the description of the operation process of the traditional notarial certificate, it should be like this: the parties apply for notarization - the notary office evaluates the application - confirms the authenticity and legality of the application items - makes, issues and delivers the notarial certificate. The running process of blockchain public certificate is similar. However, the operation mechanism behind the same operation process is not the same. The reason why the public certificate of blockchain is regarded as the Manifesto of the new environment of notarization is that it has made a subversive change to the traditional notarization certificate in the operation mechanism
01, the core operation mechanism of blockchain public certificate
the operation mechanism of blockchain public certificate is composed of two moles: "Notarization management" and "intelligent assistance". After the applicant submits the application, the blockchain notarization system relies on AI technology to audit the identity and information of the applicant. At the same time, the system will review the content of notarial evidence, and then issue a notarial certificate, at the same time on the chain filing. At the same time, the public certificate of blockchain has been formally formed, which immediately meets the online verification needs of users
the core of the operation mechanism of the notarial certificate of the blockchain lies in the application of the blockchain technology. No matter audio, video, photo or document, as long as it is stamped with a time stamp and then put on the chain, it can become an unchangeable and indestructible evidence document
the second important support in the operation mechanism of the notarial certificate of blockchain is the application of artificial intelligence. The application of this technology greatly saves the applicant's application and waiting time, and also greatly improves the speed and accuracy of the notarial office's document confirmation, eliminating the time delay of manual confirmation and possible operational errors<

02, analysis of the characteristics of the operation mechanism of the notarial certificate of blockchain
through the detailed disassembly of the operation mechanism diagram of the notarial certificate of blockchain, it is not difficult to find that compared with the operation mechanism of the traditional notarial certificate, the operation mechanism of the notarial certificate of blockchain has many noteworthy characteristics
the first is synchronization. In the process of generating the public certificate of blockchain, the actions of the applicant and the notary organization are almost synchronous, and the applicant's application and the notary organization's examination, certificate preparation and certificate issuance are almost synchronous. However, in traditional notarization, there is a time interval between the actions of all parties, which is prone to usurpation. Moreover, e to manual operation, a large amount of time cost will be generated, It further causes the delay of the process. The actions of all parties of blockchain notarization are synchronized online, and the action traces and data are generated instantaneously, thus recing the possibility of tampering and ensuring the authenticity and judicial effect of data files
the second is interactivity. In the process of generating the public certificate of blockchain, the actions of the applicant and the notarization institution are interactive - the applicant submits the application, the notarization institution's artificial intelligence audit, the certificate preparation, the certificate issuance, the data archiving, and the applicant's query are carried out alternately. Different from the traditional notarization, the applicant is more in a passive waiting state after submitting the application, which reces the participation of the applicant
dynamic again. In the process of generating the public certificate of blockchain, the evidence file is a dynamic generation process. The process of applying for the notarial certificate is the process of generating the notarial evidence, and this process itself is a part of the notarial certificate. The traditional notarization is that before the notarization, the evidence documents have been basically finalized. What the notary office does is just a process of confirmation and seal, and the dispute prevention function of notarization is weakened

it is precisely because the operation mechanism of the block chain notarial certificate is quite different from that of the traditional notarial certificate, which determines its absolute advantage over the traditional notarial certificate. On the one hand, it meets the people's requirements for efficiency in the digital age; On the other hand, it also strengthens the authenticity and legal validity of notarial documents. Its interactive feature adapts to the Internet era thinking of emphasizing interaction, which makes all parties involved in notarization enter a positive interactive state. Finally, the dynamic nature of the generation of the public certificate of the blockchain greatly gives play to the initiative of the notary organization, rather than passively confirming the existing evidence documents, which can give full play to the original preventive function of the notary.

9. I usually sell in the legal currency trading area.

10. Jinwowo network analysis believes that: blockchain technology redefines the generation mode of credit in the network: in the system, participants do not need to know the background information of other people, nor do they need to rely on the guarantee or guarantee of a third party organization. Blockchain technology ensures that the system records, transmits and stores the activities of value transfer, and the final result must be credible.
