PROOF OF KEYS - 3 JAN

Digital signatures are the standard for verifying control of bitcoin.

Test your backups, challenge your multisig cosigners. Shut your auditor up.

Be resilient by using Gatekeeper to run periodic key audits. It's open source, transmits nothing and works offline.

If you'd like extra guidance or need privacy-respecting reports to satisfy auditors (especially for SMSFs, corporate and HNWIs), CertainKey can help.
