FAQ — TruthAnchor
Frequently asked questions about TruthAnchor — the open proof infrastructure for AI agents.
What is TruthAnchor?
TruthAnchor is an open proof infrastructure that allows AI agents and users to anchor cryptographic proofs of data, actions, or content onto public blockchains. This creates immutable, verifiable audit trails.
What blockchains are supported?
Product anchoring runs on Polygon, Base, and BNB Smart Chain mainnets plus Sepolia testnet. The verified ERC-8263 reference contract is on Ethereum Mainnet — used for standard credibility and verification, not as the default user anchor path.
Do I need an account?
No. You can use Instant mode without creating an account. Accounts unlock history tracking, API access, and higher usage limits.
Is my data stored on the blockchain?
No. Only a SHA-256 hash of your content is stored on-chain. Your original data never leaves your device. The hash serves as a cryptographic fingerprint that proves the content existed at a specific time.
Can proofs be deleted or modified?
No. Once a proof is anchored on the blockchain, it is permanent and immutable. This is by design — it ensures the integrity and trustworthiness of every record.
What is batch anchoring?
Batch anchoring lets you anchor multiple items in a single blockchain transaction using a Merkle tree. This saves gas fees while maintaining individual verifiability for each item.
Will AGI make TruthAnchor obsolete?
The question inverts: how does an AGI prove to others that it deserves to be trusted? However capable agents become, three needs do not disappear — identity (who acted), accountability (what exactly was executed, when, and on what basis), and settlement (nobody releases money or authority without proof). TruthAnchor anchors the cryptographic commitments those answers rest on. The smarter and more autonomous agents get, the more valuable a tamper-proof record becomes — not less.
