1. Compared with the traditional centralization scheme, blockchain technology has the following three characteristics:
1) the core idea of blockchain is decentralization
2) the biggest subversion of blockchain lies in the establishment of credit
3) the collective maintenance of blockchain can rece the cost.
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival.

2. The following points are the characteristics of the blockchain summarized by jinwowo group:
1 - Decentralization: because the blockchain relies on each node to achieve system maintenance and ensure the authenticity of information transmission, it is based on distributed data storage without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network
2-DE Trust: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud
3 - extensible: blockchain is an underlying open source technology, on which various kinds of extension, decentralized and distrusted applications can be realized<
4 - anonymization: the two sides of data exchange can be anonymous, and the nodes in the network can exchange data without knowing each other's identity and personal information
5 - Security and reliability: because the activities between any nodes are supervised by the whole network, and the database adopts distributed storage, for hackers, first, they can't disguise and cheat, Second, we can't control the network only by conquering a node.

3. In the blockchain system, it is necessary to describe the ownership, protect the ownership, store the transaction data, distribute the ledger to an untrusted environment, add transaction records to the ledger, and decide which ledger determines the truth

According to reports, blockchain has the advantages of decentralization, distrust and tamper proof
compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

5. 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.

7. Chongqing jinwowo analysis blockchain system is open. In addition to the private information of all parties involved in the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent.
8. Blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid. When the concept of blockchain was hot, many related top domain names were registered and used as blockchain platforms.
