guess jewelry wholesale What is the difference between the public chain, the private chain is different from the alliance chain

wholesale jewelry clark street chicago According to different user needs and scene applications, the blockchain is divided into three categories: public chain, private chain (Private), and alliance chain ().
The degree of public chain decentralization. This kind of public blockchain represented by Bitcoin and Ethereum is not controlled by third -party institutions. Everyone in the world can read data records, participate in transactions, and bookkeeping the new blocks on the chain.
The program developers do not have the right to interfere with users. Participants (ie, nodes) can freely join and exit the network, and perform relevant operations according to their wishes.
The private blockchain is completely opposite. The writing permissions of the network are fully controlled by an organization or institution. Data read permissions are stipulated by the organization, either open to the outside world or have a certain degree of access restrictions.
It simply, you can understand it as a weak centralized or multi -central system. Because the participating nodes have strict restrictions and less; compared with the public chain, the time for the private chain to reach a relatively short consensus, faster transaction speed, higher efficiency, and lower cost.
The alliance chain is a blockchain between the public chain and the private chain, which can achieve "partial decentralization".
Then nodes on the chain usually have a physical institution or organization corresponding to it; participants are authorized to join the network and form related alliances of interests to jointly maintain the operation of the blockchain.
It to some extent, the alliance chain is also the category of private chains, but the degree of privatization is different. For this reason, it also has the characteristics of low cost and high efficiency, and is suitable for B2B transactions such as transactions and settlement between different entities.
In general, the entry threshold for public chains is the lowest, while the private chain and the alliance chain are restricted to openness.
