🛡️ SYMBI Symphony - W3C Trust Infrastructure for AI Agents

🌟 What is SYMBI Trust Protocol?

SYMBI Symphony is a production-ready trust infrastructure for AI agents, providing decentralized identity (DID), verifiable credentials (VC), privacy-preserving revocation, and cryptographic audit trails.

Built on W3C standards • Production-ready • No tokens required • EU AI Act compliant

💡 The Problem We Solve

AI agent ecosystems lack trust infrastructure:

• ❌ No decentralized identity - Centralized identity systems create single points of failure
• ❌ No verifiable trust - Cannot prove agent capabilities or trustworthiness
• ❌ Privacy leaks on revocation - Database-backed revocation exposes credential usage
• ❌ No audit trails - Application logs are mutable and unverifiable
• ❌ Compliance gaps - EU AI Act requires transparency and human oversight

✨ Our Solution

SYMBI Trust Protocol provides 6 core capabilities based on W3C standards:

🧪 Tested & Validated

95 tests passing • 95.3% coverage • Validated against RFC, NIST, W3C standards

🚀 Quick Start

Installation

npm install @yseeku/trust-protocol

DID Resolution

import { UniversalResolver } from '@yseeku/trust-protocol';

const resolver = new UniversalResolver();
const result = await resolver.resolve('did:web:example.com');

console.log(result.didDocument);
// Output: { id: "did:web:example.com", verificationMethod: [...], ... }

Issue Trust Declaration

import { AgentFactory } from '@yseeku/trust-protocol';

const declaration = AgentFactory.createTrustDeclaration(
  'agent-123',
  'MyAIAgent',
  {
    inspection_mandate: true,
    consent_architecture: true,
    ethical_override: true,
    continuous_validation: false,
    right_to_disconnect: false,
    moral_recognition: false
  }
);

console.log(declaration.scores.compliance_score); // 0.52
console.log(declaration.trust_level); // "MEDIUM"

Check Revocation Status

import { verifyRemoteStatus } from '@yseeku/trust-protocol';

const statusEntry = {
  id: 'https://example.com/status/1#42',
  type: 'StatusList2021Entry',
  statusPurpose: 'revocation',
  statusListIndex: '42',
  statusListCredential: 'https://example.com/status/1'
};

const result = await verifyRemoteStatus(statusEntry);
console.log(result.status); // 'active' | 'revoked' | 'suspended'

❓ Frequently Asked Questions

General

Q: What is SYMBI Symphony? A: SYMBI Symphony is a W3C-compliant trust infrastructure for AI agents. It provides decentralized identity (DIDs), verifiable credentials (VCs), privacy-preserving revocation, and cryptographic audit trails.

Q: Do I need blockchain to use SYMBI Symphony? A: No. While Symphony supports blockchain-anchored DIDs (did:ethr, did:ion), it also supports did:web (DNS-based) and did:key (purely cryptographic). Choose the method that fits your needs.

Q: Is SYMBI Symphony open source? A: Yes. MIT licensed. You can use it in commercial projects, modify it, and contribute back.

Technical

Q: What programming languages are supported? A: Currently Node.js/TypeScript. Python, Go, and Rust SDKs are on the roadmap for Q1 2026.

Q: Can I use this with OpenAI, Anthropic, or other AI providers? A: Yes. Symphony is provider-agnostic. It works with any AI service or agent system.

Q: What are the performance characteristics? A: Resolution: <50ms avg. Trust scoring: <5ms. Revocation checks: <1ms (O(1)). See Performance Benchmarks.

Q: How do I integrate with my existing AI agents? A: Check out our Integration Guides. We have examples for LangChain, AutoGPT, and custom agents.

Compliance

Q: Is SYMBI Symphony EU AI Act compliant? A: Yes. Symphony provides the transparency, auditability, and human oversight required by the EU AI Act for high-risk AI systems.

Q: What about GDPR? A: Symphony is GDPR-friendly. Users control their data (right to delete), and we use privacy-preserving revocation (no correlation tracking).

Q: Can I get SOC 2 or ISO 27001 certified using Symphony? A: Symphony provides the technical foundation (audit trails, key management, access controls), but certification is organization-specific. We can provide supporting documentation.

Ecosystem

Q: What is the relationship between SYMBI Symphony, SYMBI DAO, and YCQ Sonate? A:

• SYMBI Symphony: Open-source trust protocol (this repo)
• SYMBI DAO: Optional governance layer for protocol decisions (separate)
• YCQ Sonate: Enterprise platform built on Symphony (commercial SaaS)

Q: Do I need to participate in the DAO to use Symphony? A: No. The DAO is completely optional and only for those who want governance input.
