链书

简介

链书（Chainbook）是 B3log 开源社区提供的区块链纸质书交易平台，通过 B3T 实现共享激励与价值链。

链书主要通过如下组件实现服务：

  • 链书社：微信小程序，扫 ISBN 进行书籍上架、购买书籍、快递预约等业务操作
  • 黑客派：链书社服务端，实现账号系统、书籍管理、B3T 转账、社区论坛等
  • B3T：B3log 开源社区币，以太坊 ERC20 令牌

链书社

动机

  • 让闲置书籍继续发挥社会价值
  • 做一个真实落地的区块链应用
  • 为 B3T 赋值，扩大 B3log 开源社区影响力

使用流程

微信登录

  • 如果没有黑客派账号，直接通过链书社小程序登录即可
  • 如果已有黑客派账号，需要先到个人设置账号中绑定微信，然后再通过链书社小程序登录

交易书籍

  1. 卖家使用小程序扫书 ISBN 并设定 x 个 B3T 上架，标明寄付或到付
  2. 买家需求下单：冻结买家的 x 个 B3T
  3. 卖家快递书给买家：通过系统联系快递上门取件进行寄送
  4. 买家签收后系统将 x 个冻结 B3T 解冻并转账给卖家

在这个交易过程中：

  • 卖家主要成本是发快递的人力时间成本，寄付的话还需要支付快递费，收益是获得 x 个自定价的 B3T
  • 买家主要成本是支付 x 个 B3T，到付的话还需要支付快递费，收益是获得书

细节规则

卖家：

  • 同一个卖家，相同的书只能有一本处于在架状态
  • B3T 定价区间 [1, 10240]

买家：

  • B3T 可用余额满足书籍定价
  • 最多只能同时需求同一个卖家的 1 本书
  • 最多只能同时需求 3 本书

系统：

  • 撤销超过 3 天没有快递发货的订单，书籍回到在架状态，解冻买家 B3T
  • 撤销超过 15 天仍处于快递中的订单，书籍进行下架处理，解冻买家 B3T
  • 下架需求超过 3 次但未发货的书籍

关于 B3T

总结

链书旨在为闲置书籍创造一个全新的交易平台，让有价值的闲置书籍发挥其最大的社会价值。链书基于区块链技术，实现了高效互信的书籍共享和价值传递，最终通过 B3T 实现 B3log 开源社区基础价值的完整统一。

鸣谢

链书的诞生离不开以下项目：

  • Ethereum Project：运行智能合约的去中心化平台
  • OpenZeppelin：安全的智能合约基础库
  • INFURA：为以太坊、IPFS 提供安全、可靠和可伸缩的区块链基础设施
  • WePY：小程序组件化开发框架
