ZKsync Security Council Renames Emergency Upgrade Into Two Tiers

ZKsync Security Council proposes renaming "Emergency Upgrade" to "Instant Upgrade" with a two-tier classification: Category 1 (Security Patch) for preventative fixes, Category 2 (Emergency Response) for active incidents. Governance process, authorities, and security controls remain unchanged. Classification aims to distinguish proactive remediation from live exploits for token holders and integrators.
