VLEI

Verifiable Legal Entity Identifier System

A comprehensive implementation of verifiable credentials for legal entity identification, built with modern cryptographic standards and KERI (Key Event Receipt Infrastructure).

VLEI Example KERI Example View Code

Key Features

Cryptographic Security

Built on robust cryptographic primitives with support for multiple key types and secure key management through KERI standards.

Verifiable Credentials

Implements W3C Verifiable Credentials standard for legal entity identification with tamper-evident digital signatures.

Zero-Knowledge Verification

Verify entity relationships and roles without revealing sensitive information, enabling privacy-preserving identity verification.

About VLEI

What is VLEI?

Verifiable Legal Entity Identifiers (VLEI) are digital credentials that establish the identity and relationships of legal entities in a verifiable, tamper-evident manner.

Unlike traditional LEI (Legal Entity Identifier) systems, VLEI leverages blockchain and cryptographic technologies to provide:

  • Immutable identity records
  • Cryptographic proof of relationships
  • Privacy-preserving verification
  • Decentralized trust networks

VLEI Structure

Hierarchical Identity Structure

VLEI establishes a clear hierarchy between individual representatives and legal entities, with cryptographic proof of relationships and roles.

👤
Individual Person (Representative)
├── DID: did:ethr:0xabcdef... (John Smith's personal DID)
├── Role: "CFO"
└── Represents: Legal Entity
🏢
Legal Entity
├── DID: did:ethr:0xfedcba... (ACME Corp's DID)
├── LEI: 529900WXKG14MWNYUQ33
└── Name: "ACME Corporation"

Representative

Individual person with a specific role within the legal entity, identified by their personal DID.

Legal Entity

Organization or corporation with its own DID and official LEI identifier.

Verifiable Credential

Cryptographic proof of the representative's role and relationship to the entity.

About KERI

Key Event Receipt Infrastructure

KERI is a cryptographic key management infrastructure that provides secure, scalable, and interoperable digital identity systems.

Key features of KERI include:

  • Self-sovereign identity management
  • Cryptographic key rotation and recovery
  • Decentralized identifier (DID) support
  • Event-sourced key management
