1. 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.

2. Chongqing jinwowo analysis is based on distributed bookkeeping, collective agreement and intelligent consensus mechanism. The information characteristics of blockchain technology, such as decentralization, open sharing, authenticity and reliability, once attracted great attention. Among them, the characteristics of decentralization are particularly popular, and the attention to decentralization has existed since the birth of blockchain.
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.

The essence of decentralization in blockchain technology is 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: the data exchange between each node in the whole system does not need mutual trust. The operation rules of the whole system are open and transparent, and all data contents are open. Therefore, within the specified rule range and time range of the system, nodes can not and cannot cheat other nodes
3. Collective maintenance: data blocks in the system are jointly maintained by all nodes with maintenance function in the whole system, and these nodes with maintenance function can be participated by anyone
{rrrrrrr}
extended data:
blockchain technology never excludes supervision, and supervision nodes can easily access any blockchain network. Due to the open and transparent nature of blockchain, regulators can more easily monitor the transaction data of the whole system, and because of its tamper proof nature
once a transaction occurs, it cannot be changed or deleted, and it is impossible to cheat the supervision by data fraud, which is more concive for the supervision department to supervise the market behavior. Therefore, blockchain will become an important tool of regtech
5. 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.
6. Jinwowo network technology:
the centralized platform leads to data monopoly and data island, and only a few oligarchs enjoy the data dividend
centralization and decentralization are the differences between centralization and decentralization. Decentralization mainly refers to the empowerment of ordinary users by technology.

7. "Blockchain is a shared distributed database technology, and its advantages are mainly manifested in three aspects: distributed decentralization, no need to trust the system, tamper proof and encryption security."
first, the meaning of blockchain technology
blockchain technology is a kind of technology that uses decentralized consensus mechanism to maintain a complete, distributed and tamper proof ledger database. It can enable the participants in the blockchain to realize a unified ledger system without establishing a trust relationship. The block is a public account book, which needs multi-point maintenance; Chain is covered with timestamps, which can not be forged. Blockchain is essentially a technology that focuses on security and credibility rather than efficiency
at present, there is a database behind all systems, that is, a large account book. So it's very important who keeps this account book. Now, whose system is who will keep accounts, and the bank accounts are the records of each bank, and Alipay's account is Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book
as a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for the whole people to participate in bookkeeping, and what it will bring is the innovation of bookkeeping.

8. Chongqing jinwowo analysis features of decentralization are as follows: as the name suggests, the blockchain does not need a centralized server, and all information is stored in distributed form on each node in the chain. Even if a node is damaged or tampered, it can not affect the operation of the whole blockchain, and there will be no data disorder.
