    Cos72 Shop模块

    1. 开店的模块，帮助社区开始自己的链上Shop
    2. 社区—>多店铺
    3. 店铺—>多商品
    4. 商品基础
      1. 商品信息
      2. 商品价格
      3. 商品库存
      4. 商品维护：是否仅仅提供商品信息追加，不提供修改（IPFS和链上无法修改）；价格可以修改，链上修改；库存可以修改，也可以设置为无限；
    5. 商品分润模式
      1. 捐赠模式，指定商品在某段时间内自动捐赠到某个指定国库中（可以多捐赠同时发生）
      2. 多方分润，和捐赠类似，需要设定后自动执行，需要设定有效期
    6. 支付服务服务
      1. 基础支付服务：基于AAStar Account安全机制保护下的链上支付，包括ETHPaymaster的免gas交易服务，包括扫码支付、链接支付等更多的服务。
      2. 交易消息通知：收款到账通知，支付（动账）通知，交易状态通知（更多依赖交易状态设计）
      3. Token红包：类似于传统的红包
      4. AA分账支付：一个链接，显示总账、需要支付的人名list和金额，以及是否支付的状态。
      5. 交易退款：因为各种原因，全额或者部分退款，原路返回，需要seller和buyer协商后seller执行。
    7. 销售模式
      1. 默认所有AAstar账户体系是免gas（链上包油），实际成本需要Shop支付
      2. Pay and get：适用于现场销售的场景，例如实物店铺、线下摊位等
      3. Pay and ship: 去中心的电商，需要有众多的去中心服务商来保障全流程
      4. Pay and get online: 适用于链上资产，上架等于锁定数字资产，支付则自动transfer到支付账户（可以指定另外的账户接收）。
    8. 链上交易的风险
      1. 付款后卖家不发货
      2. 商品质量纠纷
      3. 商品售后保障
      4. 大额交易的账期和确保支付
      5. 交易保险：覆盖来回运费和破损修复等等。
    9. V0.1在本次Devcon，ETHGlobal开始之前，交付版本

      1. 基础建设完成：账户安全（BLS+DVT），流程简单（无Gas+Email登录），搭建快速（店铺+商品+交易+通知）

      2. 快速开店：在页面引入Cos72.js，然后注册一个社区，开始一个获得多个店铺

      3. 任何社区可以通过在页面引入Cos72.js，展示自己的店铺，也是用户的快速注册和登录入口。

      4. 任何商品信息，都在链上合约或者IPFS上，商品合约要存储IPFS hash信息

      5. 先支持Pay and go销售模式，当面销售
