CRYPTOCURRENCY TRANSACTION METHOD INCLUDING DELEGATED PROOF OF STAKE CONSENSUS ALGORITHM

摘要

According to the present invention, a cryptocurrency transaction method containing a delegated proof of state consensus algorithm comprises: a preliminary step of selecting whether a node participating in cryptocurrency transactions becomes a candidate node capable of generating a block proving transactions of cryptocurrency or not; an authentication step of digitizing a trust index for capabilities in which the node can perform a task for generating a block from performance information of a node for each period, and authenticating the node as a candidate node only if the trust index is greater than a predetermined critical trust index; a voting step of allowing the node to vote in proportion to stakes of cryptocurrency owned by the node for the entire cryptocurrency in order to select a representative node for generating blocks among candidate nodes; and a validation step of allowing the node to validate blocks generated by the representative node. The performance information contains information on a network connection environment of a node, and the trust index contains figures related to responsiveness of the network connection environment. Accordingly, the present invention can ensure a rapid work processing speed of a representative node.
