Description −

The did:lit method is a decentralized identifier system built on the LEDGIS blockchain platform. This method provides self-sovereign identity capabilities through a dedicated blockchain infrastructure called the Ledgis DID Chain.

The method enables management of digital identities without relying on centralized authorities, using a combination of blockchain-based identity management and public key cryptography. did:lit identifiers are created and managed through smart contracts on the LEDGIS blockchain, specifically through the led.lit system contract.

Key features include:

Blockchain-based identity management using the LEDGIS platform
Permission-based access control through controller and delegator authorities
Verifiable Credentials status management
Multi-key support with different verification relationships
Service endpoint registration capabilities

Technical Architecture:

DID Structure:

Format: did:lit:<base58-identifier>
Identifier: 21-22 characters using Base58 encoding
Example: did:lit:AEZ87t1bi5bRxmVh3ksMUi

Key Management:

Uses ECDSA secp256k1 cryptography
Supports multiple verification methods:
- authentication
- assertionMethod
- keyAgreement
- capabilityInvocation
- capabilityDelegation

Security Model:

Dual Permission System:
- controller permission for DID document management
- delegator permission for capability invocation
Smart Contract Controls through led.lit
Hierarchical Authority structure

Operations:

Create: Through regdid action
Update: Multiple specialized actions for different components
Deactivate: Through deletedid action
Read: Via Universal Resolver endpoint

Technology Stack:

Blockchain: LEDGIS platform
Smart Contracts: led.lit system contract
Cryptography: EcdsaSecp256k1
Data Storage: On-chain DID document storage
Resolution: Universal Resolver compatible

The method includes built-in support for Verifiable Credentials status management, allowing issuers to maintain credential validity states without storing personal data on-chain.
