N2 - With the advent of the blockchain technology, low throughput and scalability have gradually become technical bottlenecks. A DAG (Directed Acyclic Graph)-based blockchain system is deemed to be a potential solution to addressing both issues. However, constructing consensus protocol to meet the requirement of the consistency in a networked environment is an unsolved challenge. In this paper, we propose a novel DAG-oriented consensus mechanism. Specifically, our approach sorts and merges original blocks from a DAG structure and re-construct a single-chain-based blockchain system; hence, consensus in DAG can be achieved on new formed blocks through running the proposed global ordering scheme and block mergence operations. Blockchain-related functions can be retrieved from splitting merged blocks.
