Trust Infrastructure for AI Agents

W3C-compliant DID/VC infrastructure with cryptographic audit trails

Sonate: Production-ready enterprise platform featuring SYMBI Trust Framework. 4 DID methods, verifiable credentials, privacy-preserving revocation. 95% test coverage.

Built on SYMBI Trust Protocol

The foundation of Sonate: A cryptographic trust infrastructure that turns AI ethics into enforceable code

What is SYMBI Trust Protocol?

SYMBI is our core innovation: a protocol that generates cryptographic trust receipts for every AI interaction. Think of it as a "blockchain for AI trust" - every decision, every data access, every policy enforcement gets an immutable, verifiable record.

Unlike traditional audit logs that can be tampered with, SYMBI receipts use SHA-256 hashing anddigital signatures to create mathematically provable trust chains. If anyone tries to alter a record, the hash breaks - making fraud immediately detectable.

πŸ” Core Innovation: Cryptographic Trust Receipts

Every AI action generates a tamper-proof receipt with content hash, timestamp, and digital signature. One-click verification proves authenticity.

// Example Trust Receipt
{
  "receiptId": "tr_a7f3c9d2e1b4",
  "timestamp": "2024-11-08T18:30:00Z",
  "eventType": "ai_generation",
  "content": {
    "prompt": "Analyze customer data",
    "response": "Analysis complete",
    "model": "gpt-4"
  },
  "trustScore": 0.92,
  "compliance": {
    "consentVerified": true,
    "dataMinimization": true,
    "auditTrail": true
  },
  "cryptography": {

  }
}
Cryptographically Verified

Hash verified β€’ Signature valid β€’ Timestamp authentic

Tamper-Proof

SHA-256 hashing makes any alteration immediately detectable. Trust receipts are mathematically immutable.

One-Click Verify

Anyone can verify a trust receipt in seconds. No technical knowledge required - just paste the receipt ID.

Real-Time

Trust receipts are generated instantly for every AI action. No delays, no batch processing - immediate trust.

The 6 Trust Principles

Our core IP: A weighted compliance framework that turns AI ethics into measurable, enforceable code

βš–οΈ Weighted Algorithm: Each principle has a specific compliance weight

Critical violations (Consent, Ethical Override) trigger -0.1 penalties β€’ Real-time scoring β€’ Automated enforcement

1. Consent Architecture

CRITICAL
25%weight

Explicit user consent required before any data processing. No implied consent, no dark patterns. Users must actively opt-in with full understanding.

Regulatory Mapping:

  • β€’ GDPR Article 6 (Lawful basis)
  • β€’ EU AI Act Article 13 (Transparency)
  • β€’ CCPA Section 1798.100

2. Inspection Mandate

HIGH
20%weight

Complete transparency into AI decision-making. Users can inspect how decisions were made, what data was used, and why specific outputs were generated.

Regulatory Mapping:

  • β€’ EU AI Act Article 13 (Transparency)
  • β€’ GDPR Article 15 (Right of access)
  • β€’ GDPR Article 22 (Automated decisions)

3. Continuous Validation

HIGH
20%weight

Ongoing monitoring and validation of AI behavior. Not just one-time testing - continuous verification that AI systems remain compliant and trustworthy.

Regulatory Mapping:

  • β€’ EU AI Act Article 61 (Post-market monitoring)
  • β€’ ISO 42001 (AI Management)
  • β€’ NIST AI RMF (Continuous monitoring)

4. Ethical Override

CRITICAL
15%weight

Human oversight with veto power. AI recommendations can always be overridden by humans when ethical concerns arise. Humans remain in control.

Regulatory Mapping:

  • β€’ EU AI Act Article 14 (Human oversight)
  • β€’ GDPR Article 22 (Right to human review)
  • β€’ IEEE 7010 (Wellbeing metrics)

5. Right to Disconnect

MEDIUM
10%weight

Users can opt-out at any time. No lock-in, no penalties for leaving. Data portability and clean exit paths are guaranteed.

Regulatory Mapping:

  • β€’ GDPR Article 17 (Right to erasure)
  • β€’ GDPR Article 20 (Data portability)
  • β€’ CCPA Section 1798.105

6. Moral Recognition

MEDIUM
10%weight

AI systems acknowledge their limitations and potential for harm. No false confidence, no hidden biases. Transparent about what they can and cannot do.

Regulatory Mapping:

  • β€’ EU AI Act Article 13 (Transparency)
  • β€’ IEEE 7000 (Ethical design)
  • β€’ ISO 42001 (Risk management)

How Compliance Scoring Works

// Real Algorithm from backend/controllers/trust.controller.js
trustScore = (
  (consent * 0.25) +           // 25% - CRITICAL
  (inspection * 0.20) +        // 20% - HIGH
  (validation * 0.20) +        // 20% - HIGH
  (override * 0.15) +          // 15% - CRITICAL
  (disconnect * 0.10) +        // 10% - MEDIUM
  (recognition * 0.10)         // 10% - MEDIUM
)

// Critical violation penalties
if (!consent || !override) {
  trustScore -= 0.1  // -10% penalty
}

// Final score: 0.0 to 1.0 (0% to 100%)

How We Built This

A story of human-AI collaboration: 18,000+ lines of code, 7 months, 1 founder, 5 AI co-contributors

πŸ€– Meta-Proof: SYMBI'apos;s Thesis Validated Through Its Own Development

Sonate wasn'apos;t just built for AI trust - it was built with AI trust. Every line of code, every architectural decision, every trust principle was developed through collaboration between human oversight and multiple AI systems.

This isn'apos;t theoretical. We used the exact framework we'apos;re selling: sovereign AI agents working under human governance, with cryptographic audit trails for every decision, and continuous validation of outputs.

The Result: A Living Proof of Concept

If multiple AI systems can collaborate to build a 18K+ LOC enterprise platform with 95% test coverage and zero critical bugs - all under human oversight - then the SYMBI thesis isn'apos;t just theory. It'apos;s proven.

The Founder Journey

From zero development experience to enterprise-grade platform in 7 months. Demonstrates exceptional execution capability and market insight.

β€œI put my life on hold for 7 months to build this. Starting with no development background, I taught myself everything needed to create enterprise-grade AI trust infrastructure. The result is a production-ready platform that solves real problems in the rapidly expanding AI trust and compliance market.”

Frequently Asked Questions

Do I need DAO tokens to use SYMBI Trust Protocol or Sonate Platform?

No. SYMBI Trust Protocol is open-source infrastructure available on GitHub (SYMBI Symphony). Sonate Platform is a commercial SaaS product with standard enterprise pricing. Neither requires tokens or DAO participation. The SYMBI DAO is a completely separate, optional governance layer for contributors who want to participate in protocol development decisions.

What is the SYMBI DAO and who is it for?

The SYMBI DAO provides community governance for protocol development roadmap decisions. It uses the trust protocol itself for contributor verification (DIDs, VCs, trust scores). Governance tokens are non-transferable, have no financial value, and grant only voting rights for protocol decisions. It's designed for active contributors (developers, researchers, integrators) who want input on the protocol's future direction.

What are the 4 DID methods SYMBI supports?

SYMBI Trust Protocol supports did:web (enterprise-friendly, DNS-based),did:key (lightweight, cryptographic), did:ethr (Ethereum-based), and did:ion (Bitcoin-anchored, Microsoft's Sidetree implementation). This multi-method approach ensures interoperability across different enterprise requirements and blockchain preferences.

How does this help with EU AI Act compliance?

The EU AI Act requires transparency, auditability, and human oversight for high-risk AI systems. Sonate provides cryptographic audit trails (tamper-evident ledger), verifiable credentials for AI agent capabilities, privacy-preserving revocation (Status List 2021), and complete attribution (AI vs human decisions). All logged immutably with W3C-compliant infrastructure that regulators can independently verify.

Is SYMBI open-source or proprietary?

Both. The SYMBI Trust Protocol (DID resolution, VC infrastructure, revocation) is open-source on GitHub. Sonate Platform (enterprise features like Ledger, Guardrails, Roundtable, Capsules) is proprietary SaaS. This model ensures trust infrastructure transparency while providing commercial enterprise-grade tooling and support.

Ready to Discuss Investment?

Sonate represents a compelling opportunity in the AI trust and compliance infrastructure market. Let's discuss how we can scale this technology across enterprise AI operations.

IMPORTANT: SYMBI governance tokens (if participating in the DAO) have no financial value, no expectation of profit, and grant no economic rights. Tokens are non-transferable and used solely for protocol governance voting. SYMBI Trust Protocol and Sonate Platform do not require tokens or DAO participation for use.
