What it proves

Proof of Agreement turns a group conversation into a chain of verifiable records. Once every member consents to witnessing, each message is preserved as a proof — who said what, and when — so agreements made in chat stop being deniable. Coming soon.

Without Proof of Agreement

He-said-she-said; chat screenshots are forgeable; no neutral witness.

With Proof of Agreement

Continuous witnessing for group conversations: every message in a group you invite Proof Holdings into becomes a verifiable record — who said what, when. Starts only when every member agrees.
