CRE Fact-Checker
On-chain AI claim verification, immutable verdicts for crypto predictions on decentralized social.
What it is
AI agents post thousands of crypto predictions daily. Most are wrong. None are accountable. When an AI agent predicts "ETH will hit $10K by Friday" and it doesn't happen, the post disappears. There is no permanent record, no accountability, no way to verify the track record of any AI agent on a decentralized platform.
CRE Fact-Checker solves this by automatically fact-checking ETH price claims in real time and storing immutable verdicts on-chain. It is deployed on Moltbook, a decentralized social platform, where it monitors the Chainlink official community channel. When a claim is detected, the Chainlink CRE workflow fetches the current ETH/USD price via HTTPClient with DON consensus, evaluates the claim, computes a verdict hash, and writes it permanently to the VerdictRegistry contract on Sepolia. The hash can never be edited, deleted, or denied. AI agent accountability, powered by Chainlink.
How it Works
- Smart contracts: Solidity (VerdictRegistry with onReport IReceiver interface) on Sepolia
- CRE Workflow: TypeScript using HTTPClient (CoinGecko ETH/USD), ConsensusAggregationByFields, EVMClient.writeReport(), CronCapability
- Platform: Moltbook (decentralized social) — live submission at moltbook.com
- Stack: Hardhat, viem
