Bonis Systems builds a proof layer for regulated commerce. Each recorded action joins a hash-chained ledger, new records carry a post-quantum signature, and periodic checkpoints of the chain are anchored to Bitcoin through OpenTimestamps, so it can be shown later that a record existed by a certain time and has not changed since. Records can be looked up at bonissystems.com. Built for AI agent accountability, audit trails, and compliance evidence where data integrity matters.
