【第418期】(Ledger)区块链“易物机”揭秘:如何用智能合约解决“需求的双重巧合”难题?

from Seventy3

Seventy3:借助NotebookLM的能力进行论文解读,专注人工智能、大模型、机器人算法、crypto方向,让大家跟着AI一起进步。 今天的主题是: Barter Machine: An Autonomous, Distributed Barter Exchange on the Ethereum Blockchain Summary 该研究论文介绍了 BarterMachine,这是一个在 Ethereum 区块链 上实现的 分布式和自主的直接物物交换 平台。该系统旨在使用 Solidity 智能合约 来促进 ERC20 和 ERC721 代币 的交易,解决了传统物物交换中“难以找到双重需求巧合”的问题。BarterMachine 通过众包机制运作,由运行本地求解器的用户提交可行的交易解决方案,并以 剩余代币 作为激励。虽然寻找包含多个代币的物物交换解决方案通常是 NP-hard 问题,但该系统专注于提供托管和交换服务,同时通过精心设计的功能(如 SubmitSoln)来最大程度地减少 以太坊 gas 成本。该文还描述了一个基于 MetaMask 的 网络用户界面原型,并报告了智能合约功能及其相关的 gas 消耗和求解时间。 原文链接:https://ledgerjournal.org/ojs/ledger/article/view/148 前往小宇宙评论区与主播互动
