ABSTRACT

Through the consensus algorithm, which is the core technology of the blockchain, the same data is accurately shared between connected nodes. The use of an appropriate consensus algorithm that considers the user and the usage environment ensures efficient maintenance of data integrity and accuracy. In this paper, we proposed a performance evaluation method for efficient selection of a consensus algorithm among authorized nodes considering the characteristics of a private blockchain platform, and applied the modified item to the existing published formula considering the number of authoritative connected nodes. Through this process, it was possible to simplify the consensus process considering the stability between nodes. The stability of the consensus process can be improved by selecting an appropriate consensus algorithm based on the proposed research.
