Advantages of decentralization of blockchain Technology
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.
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 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 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
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)

Recently, many friends have come to ask questions about blockchain, such as the specific advantages of blockchain, why to invest in blockchain, and what benefits can it bring? Can't you invest in real estate and wait for the appreciation; Can't you invest in a mature market like stocks and bonds? Why invest in the emerging blockchain? Does blockchain have any investment value? And so on a series of questions, I have made the following summary, basically summarized the answers to most of the related questions:
it can be summarized in the following four aspects:
1. Blockchain has a good market prospect; 2; As an emerging technology, blockchain is recognized by many professionals including investors. It is estimated that the market value of blockchain will be about US $60 billion in 2020 and US $20 million in the global market in 2024. The considerable market prospect of blockchain is obvious
2. The cost of block chain is less; Compared with the centralized mode of relying on third-party intermediaries such as credit card payment and stock trading, the decentralized distributed structure of blockchain saves investors high handling fees and transaction costs, saves investment costs and improves transaction processing efficiency
3. Block chain is more secure and stable; The traditional centralized mode often faces serious credit crisis, but because each transaction in the blockchain is tracked and permanently recorded by the distributed public account book, the phenomenon of forgery is greatly reced, and the losses caused by the credit problems of the third party are avoided, providing security for investors' transactions
4. The programming attribute of block chain is more standard; Traditional market investors often affect their earnings because of the confusion of market levels, and the programmability of blockchain makes the market level clear, which is an innovative technology that can change people's lives
I hope it can help you to solve related problems. Please feel free to ask or discuss more details or any questions
