Prove you made it first.
When an infringement fight goes past a takedown notice, you need proof of priority that opposing counsel cannot wave away. CertNode produces a cryptographically signed, independently timestamped, Bitcoin-anchored record of your work — structured to the FRE 902(13)/(14) self-authenticating standard — that your lawyer can attach to a filing without a foundation witness.
Built for the fight that goes to court
For everyday badging, free metadata tools are fine. This is for the disputes that escalate — where the integrity and date of your proof get attacked.
Survives a stripped copy
The receipt is an external hash of your original file, not metadata embedded in it — so a re-encoded or screenshotted copy elsewhere cannot erase your proof. You keep the original; the receipt fixes its content and time.
Independent date
An RFC 3161 timestamp plus a Bitcoin anchor establish when the work existed without relying on your account or your word — the priority question in an infringement dispute.
Verifiable by the other side
Opposing counsel can verify the receipt themselves with the public key — structurally trust-independent, which is what makes it self-authenticating rather than “trust the photographer.”
Retroactive on your portfolio
