What Auditors Should Check
If you're auditing a protocol with similar architecture to Bitcoin7, these are the critical security checks that could have prevented this incident (October 2011).
- Verify all logic paths related to Other are guarded by proper access controls and input validation
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
