System Architecture

From a document to an immutable proof — in one continuous pipeline.

Every stage is instrumented and auditable. The moment a ceremony completes, the document's SHA-256 hash is written to Hedera Consensus Service on mainnet — a public, decentralized ledger no single company can alter or erase.

Verifiable Proof

QR seal + evidence pack, verify anywhere

IdenTrust X.509

The moat

Proof lives on a public, decentralized ledger — not a private database. If NotaryChain disappeared tomorrow, every seal remains independently verifiable on Hedera forever.

Application layer

React + FastAPI on MongoDB. Role-aware dashboards for admin, notary and client, with RBAC enforced on every route.

Intelligence layer

GPT-5.5 Vision drives document remediation, deepfake / liveness detection, coercion monitoring and the AI Conductor that guides notaries through statute.

Trust layer

IdenTrust X.509 PAdES sealing embedded in the PDF + a Hedera mainnet HCS anchor. Verify any seal publicly with no account.
