Abstract: Abstract: As one of the core technologies in the blockchain, consensus algorithm is an important method for the system to maintain data consistency and security. This paper firstly investigates and analyzes the relevant research on the universal consensus algorithms in the alliance chain, classifies algorithms from the perspective of whether they are based on the Byzantine problem, and combs and summarizes consensus algorithms from four aspects: problem entry, principle description, performance analysis and application scenarios. In addition, focusing on the application scenarios related to the supply chain, this paper analyzes the challenges it brings to the consensus algorithm in the alliance chain, and sorts out and summarizes the consensus algorithms in the alliance chain under this scenario. Finally, the paper discusses the challenges faced by the consensus algorithm and the direction for future development, with an intention of providing references for researchers in this field.
