Pay for proof at scale, not for the proof itself.

Every plan produces a signed document anyone can verify independently — forever, with no ProofLeaf account and no ProofLeaf servers. Pro is for sending at volume and packaging that proof into a single self-contained evidence bundle.

ProofLeaf's signatures are electronic signatures under ESIGN/UETA with a full audit trail. The OpenTimestamps anchor is a decentralized proof-of-existence, not an RFC-3161 or qualified timestamp. The default signing certificate is self-signed unless your organization supplies its own.
