社区不缺热情，缺一个被看见的地方
需求发在群里，刷两屏就沉了；报名靠接龙，谁报了谁没报要靠人点名；做完了，也只是在群里说一句「我弄好了」。社区越大、人越流动，「凭记忆办事」就越吃力——大家需要的，是一把公开的尺子。

让社区协作
有迹可循
社区协作助手「白」（Bai）
一个开源的社区协作平台，也是一本记录社区贡献的「贡献记录本」。社区在这里发任务、发公告、办活动；成员领任务、交凭证、拿积分。每一份为社区出的力，都被写成一条可追溯的记录，公开、可信。

五分钟了解 Bai 为什么做、是什么、能做什么、怎么做到。
社区的一间「公共大厅」
墙上贴着公告，谁都不会错过社区正在发生的事；桌上摆着任务墙，谁需要帮忙、谁能帮忙，都写在明处；角落里有一本贡献记录本，记下每个人为社区做过什么。它背后接入 Semi，一个身份通行多个社区应用。
从发任务到发积分，全流程线上
- Semi 身份登录，社区广场浏览与加入
- 发布、认领任务：积分、截止时间、凭证要求
- 提交凭证、审核通过或驳回重交，全程留痕
- 任务完成即发放社区积分
- 办活动、社区商城与账单、公告与动态
- 站内通知与个人主页故事线
三层分工，前端不碰链
Nuxt 3/Vue 3 前端部署在 Vercel；Node.js/Express/TypeScript 后端配 Supabase（PostgreSQL）与对象存储，部署在 Fly.io；Solidity + Hardhat 编写的备注合约 RemarkLogicV1 已上链，支持质押与自动发放，积分按约定的规则自动到账，全程可查。
Semi 管身份，Bai 管记录
登录是一次 OAuth 2.0 授权（授权码 + PKCE）；积分在 Semi 的 Safe 智能账户里发，手续费由平台代付，Bai 从头到尾不接触私钥。「发积分」与「写备注」在同一笔链上操作中完成，链上资金安全有保障，每个人的社区贡献也被同时记录下来。
从点对点直付，走向先托管后放款
计划把托管合约正式部署上线：任务赏金先锁定、验收通过才放款；商城确认收货后放款，活动在可取消截止后放款；并支持平台费与社区费、链上退款与自动对账。

Bai · Full Introduction
Community collaboration,
on the record
Community Collaboration Assistant "Bai"
An open-source community collaboration platform and a contribution ledger for communities. Communities publish tasks, announcements and events; members claim tasks, submit proof and earn points. Every bit of effort becomes a traceable, public and trustworthy record.

Overview
Five minutes on why Bai exists, what it is, what it does, and how it works.
Communities don't lack enthusiasm; they lack a place to be seen
A request posted in a group chat sinks after two scrolls. Sign-ups rely on a rolling list, and someone has to call the roll. When work is done, it's just a message saying "finished." The larger and more fluid the community, the harder it is to run on memory alone — people need a community app that brings all of this together in an organised way, which is exactly why we built Bai.
A shared "public hall" for the community
Announcements on the wall so nobody misses what's happening; a task wall on the table showing who needs help and who can help; and a contribution ledger in the corner recording what each person has done. It connects to Semi, so one identity works across community apps.
From publishing a task to issuing points — all online
- Sign in with Semi, browse and join communities
- Publish and claim tasks: points, deadlines, proof requirements
- Submit proof, approve or reject with resubmission, fully logged
- Community points issued on task completion
- Events, community marketplace and billing, announcements
- In-app notifications and a personal story timeline
Three layers; the frontend never touches the chain
A Nuxt 3/Vue 3 frontend on Vercel; a Node.js/Express/TypeScript backend with Supabase (PostgreSQL and storage) on Fly.io; and the RemarkLogicV1 remark contract written in Solidity and deployed with Hardhat, now live on-chain with staking and automatic distribution — points arrive by the agreed rules, fully auditable.
Semi handles identity, Bai handles records
Login is an OAuth 2.0 authorization (authorization code + PKCE). Points are issued from Semi's Safe smart accounts with platform-sponsored gas, and Bai never touches private keys. "Issue points" and "write remark" happen in the same on-chain operation, keeping funds safe while recording each person's contribution to the community.
From direct payment to escrow-then-release
The plan is to deploy the escrow contract: task rewards are locked first and released on approval; marketplace orders release on delivery confirmation, events after the cancellation deadline; plus platform and community fees, on-chain refunds and automatic reconciliation.
