Abstract

The invention discloses a Byzantine fault tolerance method of a data block chain authorization participation consensus based on reward and punishment and a reward and punishment method thereof, relating to the technology of fault tolerance of a data block chain. A node reward and punishment algorithm is used to ensure that commands sent by nodes in a Byzantine fault tolerant data block chain which is authorized to participate in the consensus are honest. The technical points of the invention are that the method comprises the steps of (1) selecting consensus nodes in the data block chain, wherein the number of the consensus nodes is smaller than a node total number in the data block chain, (2) allowing the consensus nodes to carry out consensus games to reach a consensus on authenticity judgment of the commands sent by the nodes in the data block chain, and (3) carrying out reward and punishment on the nodes in the block chain based on a result that the consensus nodes reach the consensus.

Description

technical field [0001] The invention relates to the fault-tolerant technology of the data block chain, in particular to a Byzantine fault-tolerant method and reward-punishment method based on reward-punishment-based data block-chain authorization to participate in consensus. Background technique [0002] Data blockchains use algorithms to guarantee fault tolerance. Traditional approaches use Proof of Work for fault tolerance. Fault tolerance is guaranteed as long as more than 50% of the total computing power of the network is honest. Proof of work, however, is energy intensive. Newer techniques use Proof of Stake for fault tolerance, where nodes stake a proof or "stake" on their version of the blockchain. With proof of stake, nodes can remain honest under the threat of economic loss, as long as more than 50% of the "stakes" in the network are honest, then fault tolerance is guaranteed. [0003] For a more efficient proof-of-stake, the data blockchain can use a Byzantine ...
