Abstract

Based on the development of digital currency, the blockchain technology has become increasingly popular, and the consensus mechanism is a critical aspect that requires further research. This paper proposes a new blockchain consensus mechanism, called UDAG, by combining the efficient chain consensus algorithm with the high concurrency of DAG structure. UDAG is based on the directed acyclic graph (DAG) structure and uses Pos-PBFT as the consensus algorithm. The proposed UDAG consensus mechanism improves transaction data in terms of timing, correlation, and immediacy compared to both the chain structure and the existing DAG structure. The experimental results demonstrate that UDAG is highly feasible, and it has the potential to significantly improve the performance of blockchain systems.
