Alliance chain development, what is alliance chain
Alliance chain only aims at members of a certain group and a limited third party. Internally, multiple preselected nodes are designated as bookkeepers. The generation of each block is jointly determined by all preselected nodes. Other access nodes can participate in the transaction, but no accounting process is involved. Other third parties can query through the API developed by the blockchain. In order to get better performance, alliance chain has certain requirements for the configuration of consensus nodes and network environment. With the access mechanism, it is easier to improve the transaction performance and avoid some problems caused by the uneven participants.
Advantages of alliance chain: strong controllability. Compared with the public chain, there are generally many nodes in the public chain. Once a blockchain is formed, the block data cannot be modified. For example, there are many nodes in bitcoin, and it is impossible to change the data. In the alliance chain, as long as most of the preselected nodes reach a consensus, the block data can be modified.
Semi centralization. To some extent, the alliance chain is only owned by the members within the alliance, because the number of nodes in the alliance chain is limited, so it is easy to reach a consensus.
Trading is fast. To some extent, the essence of alliance chain is still private chain, its number of nodes is limited, it is easy to reach a consensus, so the transaction speed is relatively slow.
Data is not made public by default. The data of the public chain is public, but the alliance chain is different. Only the internal organizations and their users of the alliance have access to the data.
Based on the advantages of alliance chain, we can know that alliance chain technology can be applied to various scenarios. For example, commodity traceability, in the hands of a commodity from the manufacturer to the user through a multi-party organization, the role of the alliance chain is to achieve multi-party joint record traceability information, when there is a problem with the commodity, the user can carry out traceability query and verify the authenticity of the commodity. Or like mutual insurance, alliance chain technology can provide permissions to mutual aid members, so that members can see the flow of all funds, increasing the trust between members.
However, as the application scenarios become more and more complex, we should try to choose a suitable blockchain type in the actual application.
