What is DID

DID is the abbreviation of ‘Decentralized Identity’ , which is a kind of digital identity without a centralized institution as the final guarantee, and is an extension and expansion in WEB 3 of the concept of "user portrait" in WEB2.

The final form of DID development may be that each user has a unique network-wide identity, and multiple local identities for segmented scenarios. Users remember and identify DIDs through domains, manage DIDs and interact with applications through wallets, and integrate different credentials and local identities on multiple chains through wallets.
