Bonis Systems builds an independent cryptographic proof layer for regulated commerce. Recorded actions join a hash-chained ledger, and periodic checkpoints of that chain are anchored to Bitcoin through OpenTimestamps, so a counterparty can verify what happened and when, without trusting Bonis Systems or needing it to be online. Proofs are downloadable and verify against public infrastructure. Built for AI agent accountability, audit trails, and compliance evidence in sectors where data integrity is load-bearing.
