TIPISTAMP lets two parties create a canonical agreement, sign the same hashed statement, and anchor its fingerprint to Bitcoin for later verification.

Field notes

The workflow separates agreement creation from later verification: terms become a canonical SHA-256 statement, both counterparties sign that same fingerprint with ES256 keys, and OpenTimestamps is used for the Bitcoin checkpoint. The homepage illustrates the model with a wholesaler's weekly price file countersigned by a garage, including a sample identifier, line-item prices, statement digest, and anchored block number. It also provides a downloadable raw verification bundle.
