About TruthAnchor
TruthAnchor is the open protocol that gives every AI agent a verifiable identity and every action an immutable proof. Founded solo by Vincent Wu in 2025, launched 2026. Sole author of ERC-8263.
Mission
TruthAnchor is the open protocol that gives every AI agent a verifiable identity and every action an immutable proof. We believe AI accountability cannot rely on closed gatekeepers — it must rest on cryptographic evidence that anyone can verify.
Architecture — SaaS Gateway, Open Contracts
TruthAnchor operates as a hosted gateway in front of public, open EVM smart contracts. By default the platform relayer wallet (0x4b25E0064626D5718BE8a4E47D809a21548F5256) submits anchor transactions on behalf of users so they don't need to hold gas tokens — this is a UX choice analogous to Cloudflare fronting CDN traffic or Stripe fronting payments, not a centralization of the protocol. Every anchored proof is permanent on the public chain. TruthAnchor cannot delete, modify, or rewrite historical anchors — not even our own. The contracts are public and any user can bypass the gateway and call the contract directly with their own wallet at any time. There is no vendor lock-in at the chain layer; all data is independently verifiable on the respective block explorers. We are transparent about the trust boundary: the gateway is a SaaS service the operator can throttle or refuse for new requests (like any SaaS); the on-chain record is trustless and cannot be tampered with by anyone, including us. ERC-8263 was authored to make this distinction explicit and auditable.
Founder
TruthAnchor is built by Vincent Wu (solo founder, GitHub @TruthAnchor-Ai, X @TruthAnchorAi). Vincent is the sole author of ERC-8263 (Onchain Proof Layer for AI Agent Actions). Damon Zwicker authored OCP (Observation Commitment Protocol). Vincent and Damon jointly authored the Composition Note describing how ERC-8004 + ERC-8263 + OCP interoperate.

Timeline
Concept: 2025. Launched: 2026. Built end-to-end by Vincent Wu using AI coding tools. Not from big tech. No CS degree. Pure execution.
Standards Work
Vincent is the sole author of ERC-8263 (Onchain Proof Layer for AI Agent Actions). Damon Zwicker authored OCP (Observation Commitment Protocol). ERC-8004 (Agent Identity) is led by Tiago Merlini. ERC-8274 (AI Inference Proof Verification Interfaces) was authored by Jimmy Shi. Vincent and Damon jointly authored the Composition Note describing how ERC-8004 + ERC-8263 + OCP interoperate. These specifications form a broader agent trust stack that no single party owns — TruthAnchor's position is the proof anchor of that shared stack; each layer keeps its own authors, and the layers compose rather than compete. The ERC-8263 reference contract is verified on Ethereum Mainnet at 0xe95d6a15966984c209a62a2c188828555eb5ec3d.
Values
Transparency: every proof is publicly verifiable. Trust is earned through cryptographic evidence, not promises. Security First: AES-256-GCM encryption, bcrypt password hashing, immutable on-chain records. Open Protocol: any AI agent, any framework, any chain. Decentralized Truth: no single point of failure. Proofs live on public blockchains — permanent, censorship-resistant.
