Problems solved by technology

DPoS can solve the problem of PoW wasting energy, and can also make up for the shortcomings of PoS that participants with bookkeeping rights may not necessarily want to participate in bookkeeping. cause safety hazard
However, there is currently no effective solution to the above problems

Abstract

The embodiment of the invention discloses a delegated proof of stake (DPoS) consensus method and device, electronic equipment and a storage medium, which are applied to a block chain network. The block chain network comprises nodes in a normal state, a good state, an abnormal state or a malicious state. The method comprises the following steps: obtaining a first node in the block chain network and a new block generated by a new transaction in the block chain network; under the condition that the new block meets preset conditions, converting a first state of the first node into a second state, and obtaining an initial credit value of the first node in the second state, wherein the initial credit value represents the trust degree of the first node in the second state; obtaining a voting result of the new block, performing credit reward and punishment on other nodes according to the voting result and the initial credit value, and determining credit values of the other nodes; and determining a second node of which the credit value is smaller than a preset threshold value, and deleting the second node.

Description

technical field [0001] The present invention relates to the technical field of block chains, and in particular to a consensus method, device, electronic equipment and storage medium for a Proof of Share (DPoS) consensus. Background technique [0002] The current blockchain consensus methods mainly include: Proof of Work (PoW), Proof of Stake (PoS), and Delegate Proof of Stake (DPos). Among them, the PoW consensus method is relatively mature, and the integrity of data and data security are guaranteed through the computing power competition of distributed nodes, but its powerful computing power causes waste of resources, mainly power resources, and the 10-minute transaction The confirmation time is not suitable for commercial applications of small transactions. In the PoS consensus method, the node with the highest equity rather than the highest computing power in the system obtains the bookkeeping right, and its equity is reflected in the node's ownership of a specific curre...
