Security — TruthAnchor

How TruthAnchor secures AI proof anchoring: multi-chain EVM smart contracts (Polygon, Base, BSC mainnets + Sepolia; ERC-8263 reference on Ethereum Mainnet), SHA-256 hashing, AES-256-GCM encryption, bcrypt password hashing.

Authentication

Session-based authentication via secure httpOnly cookies. API keys are stored as SHA-256 hashes only — we never store plaintext keys. Rate limits protect against brute force.

Blockchain Immutability

Proofs are anchored across multiple EVM chains (Polygon, Base, BNB Smart Chain mainnets + Sepolia testnet) via verified smart contracts. Once recorded, no one — including us — can modify or delete them.

Infrastructure

Hosted on enterprise-grade infrastructure with automated backups, DDoS protection, and continuous monitoring. Database connections are encrypted and access-controlled. AES-256-GCM for private key envelope encryption. bcrypt for password hashing.
