Until now, Decentralized Identifiers (DIDs) on Dock could only have one key at any moment.
Though they could be rotated over time, having only one valid key at any moment meant that the DID owner had to use the same key for all purposes. But not anymore!
到目前为止，Dock 上的去中心化标识符（DID）在任何时候都只能有一个密钥。
尽管它们可以随着时间的推移而轮换，但在任何时候只有一个有效密钥意味着 DID 所有者必须为所有目的使用相同的密钥。但现在不是了！
