This is an on-chain script implementation of did:ckb Method and did:ckb Method Local ID Extension.

The did-ckb project provides a decentralized identity (DID) solution on the Nervos CKB blockchain. It implements the did:ckb method specification, enabling creation and management of decentralized identifiers with cryptographic verification capabilities on-chain.
