What are the characteristics of alliance chain dev
The alliance chain is still a kind of private chain in essence, but it is larger than the private chain developed by a single small organization, but it is not as large as the public chain. It can be understood that it is a blockchain between the private chain and the public chain.
Alliance blockchain refers to the blockchain whose consensus process is controlled by pre selected nodes; for example, imagine a community of 15 financial institutions, each of which runs a node, and in order to make each block effective, it needs to obtain the confirmation of 10 institutions (2 / 3 confirmation). Blockchain may allow everyone to read, or be limited to participants, or take a mixed route. For example, the root hash of the block and its API (application program interface) are open to the public. The API can allow the outside world to make a limited number of queries and obtain the information about the status of the blockchain. These blockchains can be regarded as "partially decentralized".
Characteristics of alliance chain
1. Partial Decentralization: unlike the public chain, the alliance chain only belongs to the members within the alliance to some extent, and it is easy to reach a consensus, because after all, the number of nodes in the alliance chain is very limited.
2. Strong controllability: once the blockchain is formed, the public chain cannot be tampered with. This is mainly because the nodes in the public chain are generally massive. For example, there are too many bitcoin nodes, so it is almost impossible to tamper with the block data. However, as long as most of the institutions reach a consensus, the block data can be changed.
3. Data will not be disclosed by default: unlike the public chain, the data of the alliance chain is only accessible to the organizations and users in the alliance.
4. The transaction speed is very fast: like the private chain, the alliance chain is still a private chain in essence. Therefore, due to the lack of nodes, it is easy to reach a consensus, and the transaction speed is naturally much faster.
Alliance chain is suitable for use in a small range, which can be understood as a private chain. However, the scope of the alliance chain will be larger, but there is no public chain network wide open characteristics. It is a special blockchain between public chain and private chain.
Each participant in the alliance chain does not have to worry about where its own data exists. The data generated by itself can only be seen by itself. Only by authorizing the other party can the other party see your data. In this way, the problems of data privacy and security can be solved, and the decentralization can be realized. Therefore, alliance chain is one of the most valuable blockchain chains, which is more flexible and operable.
In the long run, the rapid development of alliance chain also has a great role in promoting the development of public chain. If the alliance chain develops well, it will certainly create an environment for the development of blockchain.
