Maker 的最新消息
Forcing oracle values coming from the PoS chain into the PoW chain would likely overvalue the underlying collateral of the Maker Protocol on the PoW chain, meaning that Dai on PoW would be backed by less value in reality than the system would think.
8/
强迫来自 PoS 链的预言机价值进入 PoW 链可能会高估 PoW 链上 Maker 协议的底层抵押品，这意味着 PoW 上的 Dai 所支持的实际价值将比系统想象的要少。
8/
The median.sol contract does not have any verification of chainId value, meaning that collateral prices on the PoS chain can be used via replay attacks to “force” the Maker Protocol system to “work” on the forked PoW chain.
7/
median.sol 合约没有任何对 chainId 值的验证，这意味着 PoS 链上的抵押品价格可以通过重放攻击来“强制”Maker Protocol 系统在分叉的 PoW 链上“工作”。
7/
It works by maintaining a whitelist of price feed contracts that are authorized to post price updates.
Every time a new list of prices is received, the median of these is computed and used to update the stored value in the Maker Protocol.
6/
它通过维护授权发布价格更新的价格馈送合同白名单来工作。
每次收到新的价格列表时，都会计算这些价格的中位数并用于更新 Maker 协议中的存储值。
6/
When it comes to the Maker Oracles system, the main issue is within the median.sol contract.
In short, the median is the smart contract that provides Maker's trusted reference price.

当谈到 Maker Oracles 系统时，主要问题是在 medium.sol 合约中。
简而言之，中位数是提供 Maker 可信参考价格的智能合约。

If the forked PoW Ethereum's chainId remains at 1 and does not change, replay attacks are possible.
Replay attacks mean that any transaction broadcast to the forked PoW network can be replayed on the PoS network and vice versa if both networks share the same chainId.
4/
如果分叉的 PoW 以太坊的 chainId 保持为 1 并且没有变化，则可能存在重放攻击。
重放攻击意味着任何广播到分叉 PoW 网络的交易都可以在 PoS 网络上重放，反之亦然，如果两个网络共享相同的 chainId。
4/
But, what could happen on the forked Proof of Work (PoW) chain?
First of all, we need to define what a replay attack is.
A replay attack is taking a transaction from one network and using it on another network.
3/
但是，在分叉的工作证明（PoW）链上会发生什么？
首先，我们需要定义什么是重放攻击。
重放攻击是从一个网络获取交易并在另一个网络上使用它。
3/
Once the Merge is complete, the Maker Protocol will continue to work as it does today on the Ethereum Proof of Stake (PoS) chain.
As a user, you don’t have to take any specific action to keep your Maker Vault up and running or to hold your Dai securely on the PoS chain.
2/
合并完成后，Maker 协议将继续像现在一样在以太坊权益证明 (PoS) 链上运行。
作为用户，您无需采取任何特定行动来保持您的 Maker Vault 正常运行或将您的 Dai 安全地保存在 PoS 链上。
2/
The Merge is coming, a forked PoW Ethereum chain is possible, and its chainId set at 1 poses a threat due to replay attacks.
On the eve of this situation, the Protocol Engineering Core Unit outlined the implications of this risk for the Maker Oracle Protocol.

1/
Merge 即将到来，一个分叉的 PoW 以太坊链成为可能，并且它的 chainId 设置为 1 由于重放攻击而构成威胁。
在这种情况发生前夕，协议工程核心单元概述了这种风险对 Maker Oracle 协议的影响。

RT: Users of @MakerDAO can now mint $DAI for free 💸
After an executive vote raised the debt ceiling for its $stETH vault to 200M $DAI, users can now create $DAI against $WstETH collateral without paying any fees on the position to Maker.

RT: 💡The @MakerDAO Governance reduced the stability fee for WSTETH-B Vaults to 0%.
This means that you can currently mint $DAI for free using @LidoFinance's $wstETH (wrapped $stETH).
Current WSTETH-B config is:
- 0% Stability fee
- 5,000 DAI min. debt (dust)
- 185% min. c-ratio https://twitter.com/MakerDAO/s...
RT：💡@MakerDAO 治理将 WSTETH-B 保险库的稳定费降低到 0%。
这意味着您目前可以使用@LidoFinance 的 $wstETH（包装好的 $stETH）免费铸造 $DAI。
当前 WSTETH-B 配置为：
- 0% 稳定费
- 5,000 DAI 分钟。债务（灰尘）
- 185% 分钟。 c 比率 https://twitter.com/MakerDAO/s...
