Gitcoin中心化的实现
https://gitcoin.co/grants/apollo?

需求：

1. 把Gitcoin的流程操作一遍，每一步的UI都截图
2. 设计Rust的API接口，全局变量，mapping

问题：

1. 项目方如何取这个grant的资金？ 是融资结束给他，还是验收完给他？
2. 如果社区投资多余grant初始定的目标怎么办？In reality, there are seven contributions, of which six are monthly. These were provided in the following amounts: $5, $10, $5, $333, $18, $333, $665. When you run these numbers through the CLR formula, you get $5,500 as the optimal CLR contribution. To peel the onion back one last layer, the philanthropist could decide to ‘top-off’ Austin’s grant to the stated goal ($1,000/mo), rather than providing the full match reported by CLR.
3. 如果项目到期了还没有完成目标怎么办？
4. 如何激励用户参与投票，参与grant能拿到什么代币？平台币更好
5. 是否要跟identiy结合，参与投票是否必须要注册过identity，我们的项目可以给identity增加应用场景
6. 如果项目方众筹失败，委员会判定之后，用户可以取回自己的资金，如果自动把币返回给用户?

API设计

项目方

1. apply - 提交项目申请（名称，到期时间），提交了之后需要委员会通过才能上架
2. withdraw - 项目完成之后资金可获得之后，提取项目grant资金
3. 需要能查询所有用户的赞助份额
4. 需要能按照钱包地址查询赞助份额

用户

1. 查看项目详情(可能需要存储在IPFS）
2. 在参与之前查看投钱能获得匹配的数额（预测）
3. 参与项目
4. 查看自己的参与记录（这个可以通过查询钱包记录获得，不需要签名操作）
5. 如果项目众筹失败，赎回自己投资的币
6. 未来：声望系统，用户参与项目投票，获得声望值

委员会（波卡官方）

1. propose - 提出议程，让委员会投票，proposal也需要有最小通过，过期时间
   议程有几种类型，通过上架，允许提款，设置全局变量
2. approve - 通过一个proposal

In reality, there are seven contributions, of which six are monthly. These were provided in the following amounts: $5, $10, $5, $333, $18, $333, $665. When you run these numbers through the CLR formula, you get $5,500 as the optimal CLR contribution. To peel the onion back one last layer, the philanthropist could decide to ‘top-off’ Austin’s grant to the stated goal ($1,000/mo), rather than providing the full match reported by CLR.

这个计算没有理解。
