摘要
Abstract
Directed acyclic graph(DAG)blockchain technology has more advantages than Satoshi Nakamoto's longest chain in terms of performance and certainty.The core problem in DAG blockchain technology is transaction sequencing,which introduces the connectivity limit value(CLV).It can be inferred that the CLV of Satoshi Nakamoto's longest chain is zero,ensuring that the security of the network reaches an extremely high level,but the parallelism of transaction verification is poor.For this reason,this paper conducts a generalized analysis of the DAG blockchain expansion plan.The DAG blockchain network has high concurrency,but the value of CLV is non-zero,and the corresponding security is affected.This paper explored the relationship between the connectivity limit and the security threshold of the network,network delay,etc.,and aimed to ensure the balance between the security threshold and network delay in the DAG blockchain network.The method gave a balance relationship and proposed a reasonable optimization between safety and delay.In addition,it analyzed the CLV value of the hourglass block in the DAG blockchain and gave reasonable sugges-tions.关键词
