Description −

The did:bit method is a blockchain-based DID system built on the Nervos CKB blockchain that provides decentralized identifiers through the .bit naming system. This method integrates domain name functionality with decentralized identity management, allowing users to create human-readable identifiers with a .bit suffix.

The system supports cross-chain account management and can be used for multiple purposes including:

Cryptocurrency transfers
Domain name resolution
Identity authentication
Web3 profile management

Each did:bit identifier is tied to a .bit name that can be registered and managed through the blockchain. The method supports multiple blockchain networks and various cryptographic algorithms, including ECDSA and EdDSA, making it compatible with different blockchain ecosystems like Ethereum, TRON, and Mixin.

A key feature is its ability to handle custom records through a flexible data structure, allowing users to define additional service endpoints and verification methods beyond the default ones. The system automatically generates a Web3 Public Profile for each DID and includes built-in support for multiple verification relationships.
