What Do These Proofs Prove?
Every workflow run creates a verifiable chain from live on-chain data to an immutable Sepolia record. Anyone can independently verify that a specific health assessment was made at a specific time.
1
CRE Workflow Reads On-Chain
Each workflow reads live Ethereum mainnet data — staking pools, Morpho markets, Curve balances, price feeds — via EVMClient.callContract().
2
Snapshot → ABI Encode
Key metrics (utilization, fill %, imbalance, timestamps) are ABI-encoded using Solidity parameter types — the same encoding used by smart contracts.
3
keccak256 Hash
The encoded payload is hashed with keccak256 — Ethereum's native hash function. This creates a unique, deterministic fingerprint of the exact data observed.
4
On-Chain Proof
The hash + risk level are written to SentinelRegistry.recordHealth() on Sepolia. Block timestamp provides an unforgeable record of when the assessment was made.
How to verify a record
1. Take any snapshot JSON from this dashboard
2. ABI-encode the key fields (timestamp, workflow, risk, metrics)
3. Compute keccak256 of the encoded bytes
4. Compare with the snapshotHash stored on-chain

LAA: Live on CRE Mainnet DON
The LINK AI Arbitrage workflow runs on Chainlink's Decentralized Oracle Network, 7x/day. Multiple independent nodes execute the workflow and reach consensus. Real mainnet data, real AI analysis, real on-chain proofs.
Other Workflows: Local Simulate
The remaining 7 workflows run via cre simulate locally. Snapshot data is real (live mainnet reads via EVMClient), but proofs are signed by a single operator key.
