What is a DID Wallet?

I see this term in the source code, but what is that planned for?

There is an entry in the Great Chia Glossary:

  • Decentralized ID - A decentralized ID is a smart coin that enables a wallet to act as an ID which can create messages to other IDs. Based on the work of the identity foundation.

More details on the original DID proposal can be found here: W3C Decentralized Identifiers (DIDs) v1.0
