TIPS: Transaction Inclusion Protocol With Signaling in DAG-Based Blockchain

Directed Acyclic Graph (DAG) is a popular approach to achieve scalability of blockchain networks. Due its high efficiency in data communication and great scalability, DAG has been widely adopted many applications such as Internet Things (IoT) Decentralized Finance (DeFi). DAG-based blockchain, nevertheless, faces the key challenge transaction inclusion collision due concurrency network delay. Particularly, leads revenue throughput dilemmas, which would greatly degrade system performance. In this paper, we propose “TIPS”, Transaction Inclusion Protocol with Signaling, broadcasts signal indicating transactions block. We show that prompt broadcast signal, TIPS substantially reduces thus resolves these dilemmas. Moreover, can defend against both denial-of-service delay-of-service attacks. also conduct intensive experiments demonstrate superior performance proposed protocol.
