Several chains on the classified digital collection of blockchain under popular science

A simple understanding of blockchain is a distributed public ledger . This ledger is connected by various blocks into a chain, and each node on the chain can record information to form a point-to-point accounting system. According to different application scenarios, it is generally divided into three types: public chain , private chain and alliance chain .

Simply understand the difference:

Public chain : A public chain refers to a blockchain that anyone can participate in. The public chain is the blockchain with the highest degree of decentralization, which is not controlled by institutions, and the entire ledger is open and transparent to everyone. Anyone can query transactions, send transactions, and participate in bookkeeping on the public chain. Joining the public chain does not require anyone’s authorization, and can join or leave freely, so the public chain is also called a non-licensed chain. In layman’s terms, everyone can access, read, open and transparent, and completely decentralized. It’s like you show your love for the festival, and you send a circle of friends, everyone can see that. Typical representatives are Bitcoin, Ethereum, EOS, etc.

Private chain : Contrary to the public chain’s ledger that is open and transparent to everyone and can be recorded by everyone, a private chain means that the blockchain bookkeeping authority is only in the hands of one person or an organization, and the authority to participate in bookkeeping It is formulated by the organization, and the read permission can be open to the other party or restricted to any degree. In layman’s terms, it is open to a single person or entity, and is only used within private organizations, such as companies. It’s like a brokenhearted you posting on your Moments in the middle of the night, only you can see that kind of thing. Private chains are suitable for companies or organizations, and many large financial institutions tend to use private chains. Typical representative of the Linux Foundation project.

Alliance chain : The degree of publicity of the ledger of the alliance chain is between the public chain and the private chain. The alliance chain refers to the blockchain jointly managed and maintained by multiple institutions, and the nodes participating in the blockchain are selected in advance. The alliance chain also only opens all or part of the functions to the members of the alliance. The reading, writing and accounting rules of the information on the chain are set according to the consensus of the alliance. It’s like a circle of friends who wants to post interesting pictures, block parents and family members, and only show them to good friends. The consortium chain is mainly suitable for trade and supervision of subordinate units and branches by industry associations and large chain enterprises. Typical representative of R3 Blockchain Alliance (International Banking and Financial Institution Cooperation Organization).
