+## Overview
+The DID module implements W3C Decentralized Identifiers (DIDs) with support for WebAuthn, verifiable credentials, and external wallet linking.

+## Implementation Details
+
+{{if eq .MethodDescriptorProto.Name "CreateDID"}}
+- Creates a new W3C-compliant DID document
+- Automatically generates unique DID identifier
+- Can optionally create an associated vault for secure storage
+- Supports multiple verification methods and service endpoints
+{{else if eq .MethodDescriptorProto.Name "UpdateDID"}}
+- Updates an existing DID document
+- Maintains version history for auditability
+- Only controller can perform updates
+- Preserves immutable fields like creation timestamp
+{{else if eq .MethodDescriptorProto.Name "DeactivateDID"}}
+- Permanently deactivates a DID document
+- Cannot be reversed once deactivated
+- Maintains deactivated state for historical reference
+- Revokes all associated credentials
+{{else if eq .MethodDescriptorProto.Name "AddVerificationMethod"}}
+- Adds new cryptographic verification methods
+- Supports Ed25519, ECDSA, RSA, and WebAuthn
+- Can specify verification relationships (authentication, assertion, etc.)
+- Enables multi-signature capabilities
+{{else if eq .MethodDescriptorProto.Name "RemoveVerificationMethod"}}
+- Removes verification methods from DID document
+- Cannot remove the last remaining verification method
+- Updates all related verification relationships
+{{else if eq .MethodDescriptorProto.Name "AddService"}}
+- Adds service endpoints to DID document
+- Enables discovery of services associated with DID
+- Supports multiple service types and endpoints
+{{else if eq .MethodDescriptorProto.Name "RemoveService"}}
+- Removes service endpoints from DID document
+- Cleans up service discovery metadata
+{{else if eq .MethodDescriptorProto.Name "IssueVerifiableCredential"}}
+- Issues W3C Verifiable Credentials
+- Cryptographically signed by issuer's DID
+- Supports custom credential schemas
+- Includes issuance and expiration dates
+{{else if eq .MethodDescriptorProto.Name "RevokeVerifiableCredential"}}
+- Revokes previously issued credentials
+- Maintains revocation registry on-chain
+- Includes revocation reason for audit trail
+{{else if eq .MethodDescriptorProto.Name "LinkExternalWallet"}}
+- Links external blockchain wallets to DID
+- Requires cryptographic proof of wallet ownership
+- Supports Ethereum, Cosmos, and other chains
+- Enables cross-chain identity bridging
+{{else if eq .MethodDescriptorProto.Name "RegisterWebAuthnCredential"}}
+- Registers WebAuthn credentials for passwordless authentication
+- Creates new DID with WebAuthn as primary verification method
+- Supports gasless onboarding for new users
+- Can automatically create associated vault
+- Enables biometric authentication (Face ID, Touch ID, etc.)
+{{end}}
+
+## Security Considerations
+
+- All DID operations require controller authorization
+- Cryptographic signatures validate all changes
+- WebAuthn provides phishing-resistant authentication
+- External wallet linking requires ownership proofs
+- Verifiable credentials include tamper-evident signatures
