Verify a disclosure
Auditor-ready evidence on tap. Confirm any FileBRSR number is authentic, untampered and traceable to its emission-factor source — in seconds, with no login and no manual audit trail to assemble.
Auditor-ready, without the manual audit
Every number FileBRSR publishes carries its own proof. Your auditor, regulator or buyer confirms it in seconds — no spreadsheets to reconcile, no evidence trail to chase. The cryptography runs underneath; the outcome is a figure they can trust on sight.
1 · Signed at source
When a calculation is published, FileBRSR signs the value, factor and method with an Ed25519 key. The signature travels with the number.
2 · Recorded on a ledger
Each disclosure is written to an append-only ledger. Figures can't be silently edited after publishing — any change is detectable.
3 · Verified by anyone
Paste a calculation ID above to re-check the signature, trace the emission factor to its source, and download an auditor evidence bundle.
