Orynq AI Auditability

Community Author Cardano

What It Does

Creates tamper-proof audit trails for AI conversations. Each message is hashed into a rolling SHA-256 chain where modifying any entry invalidates all subsequent hashes — making tampering immediately detectable.

The hash chain is created locally with zero setup required. Optionally, it can be anchored to the Materios partner chain for permanent blockchain immutability, with certified receipts batched into Cardano mainnet transactions.

Suggested Trigger Words

  • "audit my AI"
  • "create audit trail"
  • "blockchain audit"
  • "proof of inference"
  • "verify AI"
  • "AI accountability"
  • "audit this conversation"
  • "run orynq"
  • "anchor this session"
  • "anchor this conversation"
  • "record AI decision"
  • "log this to blockchain"
  • "start audit"
  • "chain of custody"

Setup

No setup required for local audit trails. Upload the ability and go.

For blockchain anchoring (optional):

Path Setup Who pays fees
Sponsored Set MATERIOS_GATEWAY_API_KEY in main.py FPS (included)
Permissionless Create a Materios wallet + get MATRA from faucet via orynq-sdk You (free from faucet)

How It Works

  1. Trigger with a phrase like "audit my AI" or "run orynq"
  2. Speak the messages you want in the audit trail
  3. Say "done" when finished
  4. The ability builds a SHA-256 rolling hash chain — this is already tamper-proof locally
  5. You're asked if you want to also anchor it to the blockchain
  6. If yes: the trace is uploaded to the Materios blob gateway, certified by 10 independent attestors, and batched into a Cardano mainnet anchor transaction

Example Conversation

User: "Audit this conversation" AI: "I will create a tamper-proof audit trail. Tell me what to include." User: "The model recommended treatment plan A for patient 42" AI: "Got it. Say more to add entries, or say done when finished." User: "Done" AI: "Built a 1-entry hash chain. Anchor hash: 3f8a... This is already tamper-proof locally. Would you also like to anchor it to the blockchain?" User: "Yes" AI: "Your audit trail was uploaded to Materios. The committee will certify it and batch it into a Cardano mainnet transaction automatically."

Why Auditability Matters

As AI systems make increasingly consequential decisions, organizations need provable records of what AI said and when. Traditional logging can be altered. Hash chain audit trails provide:

  • Tamper evidence — Any modification breaks the chain
  • Independent verification — Anyone can recompute the hashes
  • Blockchain immutability — Optional on-chain anchoring via Cardano
  • Regulatory compliance — Immutable records for audit requirements

Technical Details

  • Hash algorithm: SHA-256 rolling chain (each entry includes the previous hash)
  • Local artifact: Always created, zero dependencies
  • Blockchain: Cardano mainnet via Materios batched anchoring (metadata label 8746)
  • Committee: 10 independent attestors verify data availability before certification
  • Explorer: materios.fluxpointstudios.com/explorer
  • SDK: orynq-sdk
