Upgradeable Decentralized Identity - DID Method Traits

The article discusses the concept of Decentralized Identifier (DID) Method Traits, which are testable properties about DID methods that can help implementers choose the right method for their use case. These traits can prevent interoperability issues among different DID methods and provide a way for users to upgrade their decentralized identity by leveraging existing key-based accounts and grafting them onto more featureful DID methods as needed. The author also mentions their plan to write a paper on this topic for the Rebooting the Web of Trust (RWOT) conference in The Hague.
