Introduction to blockchain and application practice of decentral

1. Chongqing jinwowo: the decentralized trust mechanism means that first of all, blockchain projects need to complete the recognized accuracy of information records. In terms of pure digital business, the purpose and value of blockchain can be achieved by ensuring the recognized accuracy.

2. Decentralization is a subversive feature of blockchain technology. It does not need centralized agent and realizes a kind of point-to-point direct interaction, which makes the information interaction mode of high efficiency, large scale and no centralized agent become a reality
jinwowo group will use blockchain technology to promote the legalization of big data business. The encryption of blockchain technology can ensure that the privacy of data sources can be better protected when big data is called, so as to eliminate the bad phenomenon of illegal reselling of big data and rebuild the rules of legal circulation and application in the data market.

3. On the Internet, the most typical example of centralization is the portal website. By collecting all the information on the Internet on its own platform, the portal website forms a central node, and then extends many branches from this node. Generally speaking, only one node is making decisions. According to the analysis of jinwowo network technology, the characteristics leading to centralization are as follows:

1. The central node grasps the information of distributed nodes

2. The sub nodes do not master the information of other nodes (centralization, non-public transactions)

moreover, the pain point of centralization is that the security of the system depends on the security of the central node, and the distributed node has no control over it.

4. Chongqing jinwowo network: decentralization, which is different from the traditional way of centralization. There is no center, or everyone is the center; Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also to share and the data of the whole ledger synchronously. At the same time, blockchain also has the characteristics of disintermediation and information transparency.

5. Decentralizing is not to do without the center, but to let the nodes freely choose and decide the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center. In a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes. At present, many projects are being decentralized. GSN social bank is also decentralized. However, GSN reces the cost of credit investigation and enables unlimited use and sharing of trust data. GSN can greatly rece the false problem of massive data, so that data collection, processing and use can have better convenience. GSN expands the coverage of credit evaluation, expands the scale of the community, and uses distributed technology to collect data and information of user groups that can not be considered in the traditional mode through surveys. At the same time, GSN can carry out credit evaluation for special groups, that is, those who have no registered bank accounts but can contact with the Internet, so as to expand the scope of credit proct services. GSN reces the cost of credit proct management, so that credit evaluation, pricing, contracts can be automatically executed and managed without additional human participation, which greatly reces the cost of credit proct management, and greatly improves the scale of bank credit business processing. GSN improves the ability of credit to create value. Through the trust mechanism in the chain, the whole process of credit procts can have the ability of dynamic programming, which effectively expands the space of credit procts to create value.

The characteristics of decentralization in blockchain technology are decentralization, distrust and collective maintenance

Decentralization: there is no centralized hardware or management organization in the whole network, the rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system. Therefore, it can also be considered that the blockchain system has excellent robustness

2. Distrust: there is no need to trust each other when participating in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are also open. Therefore, in the specified rule range and time range of the system, nodes cannot and cannot cheat other nodes

3. Collective maintenance: the data blocks in the system are jointly maintained by all the nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone

extended data

blockchain technology has never excluded supervision, and supervision nodes can easily access any blockchain network. Because of the openness and transparency of the blockchain, the regulatory authorities can monitor the transaction data of the whole system more conveniently, and because of the anti tampering property of the blockchain

once a transaction occurs, it can't be changed or deleted, so it's impossible for the data fraud to hoodwink the supervision, which is more concive to the supervision of the regulatory authorities on the market behavior. Thus, blockchain will become an important tool for regulatory Technology (regtech)
