Background

Block chains can be generally classified into public chains, federation chains, and private chains, depending on access rights. The public chain refers to a block chain which can be accessed by anyone according to a protocol and is in consensus; the alliance chain is a block chain of which the consensus process is controlled by a preselected node; private chain refers to a chain of blocks that are authorized in an organization and are fully controlled by the organization.

The block chain is generally divided into several large technical points such as consensus algorithm, cryptography, P2P network and the like at the technical level. Where the consensus algorithm is the most core part of the blockchain project, and there is a distribution, consensus needs to be achieved.

As a BFT consensus protocol for asynchronous networks, honeybadger bayer fault Tolerance (honeybadger BFT) does not depend on any time assumption about network environment, compared with the conventional Practical Bayer Fault Tolerance (PBFT), honeybadger BFT has higher processing efficiency and is therefore recognized by more and more organizations.

The existing block chain consensus method generally needs to be connected with most nodes in the consensus process to acquire votes. The node has larger dependence on the network body, and the data transmission efficiency of the system is difficult to improve; secondly, in the actual data sharing application process, especially in the state that data production, storage and sharing involve multiple parties, when the production result and the storage result of the data are influenced by risks such as attack, tampering and the like, the credibility of the data authenticity is poor, and even if the authority of the prover is used to force the trust of other parties to be promoted at a non-mathematical proving level, the trust result is lack of scientificity and commonality.
