Decentralized Identity (DID) on CKB
What might a new protocol bring to the ecosystem?
Sparkling
An NFT is a unique digital object, which means it is feasible to use this to generate a decentralized identity to accomplish any task we can think of.
We saw recently a post made on Nervos Talk describing such a protocol. In this protocol, each NFT describes a different authorized characteristic a user might qualify for. This could be used to regulate who can participate in a token sale for instance, without going through the effort that is required to complete this authorization in an off-chain, centralized way.
The proposed design has three layers: issuer, NFT type, and the specific NFT. The issuer is an authority responsible for authentication, the NFT category represents a set of NFTs with the same characteristics, such as Citizenship, Driver's License, Qualified Investor, etc. and the third layer is the record of ownership by a specific user.
NFTs on CKB are an exciting new development, we previously covered the IAMM protocol and are looking forward to seeing what this decentralized identity solution brings to the Nervos ecosystem!
RFC
Nervos applies the RFC (Request for Comments) process for implementing every building block of the protocol. There were 27 previous RFCs, which can be found here.
