AI总结:

针对基于DAG的DLT节点区块感知差异大、核心组件依赖复杂的研究需求,本文提出基于智能体的开源模拟器TangleSim,可模拟Tangle 2.0共识协议的全链路要素,支持多场景下的协议性能探究。

摘要:

基于有向无环图(DAG)的分布式账本技术(DLT)支持对账本的并行、异步写入访问。因此,不同节点对最新区块的感知可能存在显著差异,而点对点(P2P)层的底层网络特性会直接影响协议的性能。此外,多个核心组件之间更强的相互依赖性,要求采用更复杂、更完整的方法来研究此类DLT。本文提出了一款基于智能体的开源模拟器,适用于部署无领导者Tangle 2.0共识协议的大规模网络。其模拟范围涵盖:对底层点对点通信建模(包含网络拓扑、丢包、异构延迟)、具备可靠广播特性的gossip协议、底层基于DAG的数据结构以及共识协议。该模拟器可支持我们探究该协议在不同网络环境及不同攻击场景下的性能表现。

英文摘要:

DAG-based DLTs allow for parallel, asynchronous writing access to a ledger. Consequently, the perception of the most recent blocks may differ considerably between nodes, and the underlying network properties of the P2P layer have a direct impact on the performance of the protocol. Moreover, the stronger inter-dependencies of several core components demand a more complex and complete approach to studying such DLTs. This paper presents an agent-based, open-sourced simulator for large-scale networks that implement the leaderless Tangle 2.0 consensus protocol. Its scope includes modelling the underlying peer-to-peer communication with network topology, package loss, heterogeneous latency, the gossip protocol with reliable broadcast qualities, the underlying DAG-based data structure, and the consensus protocol. The simulator allows us to explore the performance of the protocol in different network environments, as well as different attack scenarios.
