What is CertNode?
CertNode creates permanent, verifiable proof of digital events. Transactions, content, contracts, AI decisions — when something goes wrong, you can prove exactly what happened, when it happened, and who authorized it.
Chargebacks, content theft, contract disputes, AI accountability — one platform.
The Accountability Stack
Four types of cryptographic proof. Four accountability outcomes.
Timestamps
"When did this exist?"
3-layer verification: CertNode signature, RFC 3161 TSA, Bitcoin anchor.

"Who verified this?"
Notarization for the AI age. Multi-party approval with identity verification.
