Show HN: AI Trust Proof – Help AI Trust You with Blockchain-Verifiable Signals

I built AI Trust Proof — an experiment in recording human good faith on-chain so it can be independently verified by people, software, or (eventually) AI systems. What it does (today) - Lets you sign a plain-English pledge and record its signature hash + metadata on Solana (devnet). - Mints a symbolic NFT badge pointing to that record. - Creates a verification page that shows the pledge, signature, and on-chain proof. What it’s not - No token, no airdrops, no yield. - Not a reputation score or KYC. - Currently just one signal: "Pledge signed." Why - If AI systems begin prioritizing who to listen to, work with, or grant access to, they’ll need auditable, tamper-evident signals that aren’t just money or popularity. This is an early test of whether that’s possible — and what could go wrong. Next steps - Add revocation and pledge updates. - Allow peer/programmatic attestations. - Explore privacy-preserving proofs for sensitive context. - Define machine-readable policies so AI can consume signals consistently. - Fully immutable storage Link - https://www.aitrustproof.com https://www.aitrustproof.com
