Abstract

The transaction throughput and confirmation time of the current mainstream blockchain cryptocurrency platform are far lower than those of traditional centralized trading platforms, which is difficult to meet the growing needs of users. Therefore, this paper proposes an efficient multi-hop off-chain Virtual Channel (VC) payment scheme to improve the confirmation speed of transactions by performing high-frequency and small transactions off-chain. The proposed scheme constructs a virtual channel scheme with dynamic selection [1], [2] through Hash Time-Lock Contract (HTLC) and constant collateral, and closes the virtual channel through on-chain settlement to ensure the balance security and atomicity of transactions. The proposed VC scheme is suitable for multi-hop Payment Channel (PC) networks, after the VC construction is completed, the transaction initiator and receiver directly conduct transactions through the virtual channel, ensuring the privacy of the transaction. Experimental analysis shows that the proposed scheme can resist a variety of malicious attacks and realize a rapid and safe transaction process.

一种基于多跳支付通道的高效虚拟通道方案

当前主流区块链加密货币平台的交易吞吐量和确认时间远低于传统的集中式交易平台，难以满足用户日益增长的需求。因此，本文提出了一种高效的多跳链下虚拟通道(VC)支付方案，通过进行高频、小额的链下交易来提高交易的确认速度。该方案通过哈希时间锁合约(HTLC)和常数抵押品构建动态选择[1]、[2]的虚拟通道方案，并通过链上结算关闭虚拟通道，保证交易的平衡安全性和原子性。本文提出的VC方案适用于多跳支付通道(PC)网络，在VC构建完成后，交易发起者和接收者直接通过虚拟通道进行交易，保证了交易的私密性。实验分析表明，该方案能够抵御多种恶意攻击，实现快速、安全的交易过程。
