The essence of decentralization of blockchain technology is to r
The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine 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
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

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.
(1) fault tolerance: once there is a problem in the center, other nodes are easy to collapse. The centralized system is unlikely to be unexpected, because it depends on other nodes, and other nodes can not have problems together
(2) anti attack ability: decentralized system will make the cost of being attacked higher, because it lacks a sensitive central point, and the central point is more likely to be attacked by low cost. The reason is that we should all understand that the attack center may completely collapse, which is why more and more investors want the decentralized technology to become more mature
(3) anti Collusion: it is difficult for the participants in the decentralized system to sacrifice other participants and plot to make their own profits.
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

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 robustness2. 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

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)
