🎛️协议相关配置信息

🖌️ 设计理念

我们在Alpaca Finance中设计了许多可配置的参数。虽然最初的参数配置是由核心开发人员来设定的，但我们已经计划来让治理社区通过投票的方式，来决定是否更改配置参数。

​⏳ 时间锁

时间锁 Timelock 是一个延迟本项目更改生效的智能合约。这个时间锁合约，是 Alpaca Finance 项目上所有合约的拥有者（owner）。因此，每一次合约变更生效都需要通过这个时间锁合约，使得时间锁合约作为护城河来保障资金安全。

本质上，管理员（团队核心开发人员）每一次的操作都需要通过这个时间锁合约，并且操作都是24小时后才生效。具体来说，管理员执行的每个命令就像一笔订单一样排队进入队列，然后等待24小时候才会执行。这是一个可靠的安全特性，使社区能够提前看到所有合约更新操作，并提前做好准备。如果发现有任何可疑操作的地方，用户可以在合约升级生效前，从资金池里提取他们的资金。

下面的这些合约拥有者都是时间锁合约

  • 所有的资金池合约

  • 公平发行合约

  • 所有的系统运行合约

  • 所有价格预言机合约

  • 所有系统配置合约

✏️ ​多重签名钱包

作为附加的安全层，我们还使用了多重签名钱包。任何要伫列 (queue)  进入我们的 Timelock 合约的更改都需要经过多重签名的批准，从而增加了另一层安全性。

多重签名目前有 4 个签名者，至少需要 2 个签名者才能签署交易。

    • _strategyAddresses = Addresses for the strategy contract

    • _ok = Can be either true or false. If the _strategyAddresses above need to be disabled then set _ok = false

  • setCriticalStrategies(_addStrategy, _liquidateStrategy)

    • _addStrategy = Set default addStrategy

    • _liquidateStrategy = Set default liquidateStrategy

SimplePriceOracle Contract / 价格预言机合约
