We are excited to announce the formation of the ZKsync Security Council, a significant milestone in ZKsync’s journey towards a decentralized and secure ecosystem. 

The Role of the Security Council

The ZKsync Security Council is a governance body responsible for overseeing critical aspects of the ZKsync protocol. Security Council members have the following key responsibilities:

  • Emergency Response and System Freeze: Evaluate the need for, and potentially implement a freeze of, the ZKsync protocol when necessary, based on security assessments. This authority is crucial for responding to critical security threats.
  • Protocol Governor Proposal Risk Review: Promptly, diligently, and independently conduct security reviews on Protocol Governor proposals that have been approved by the Token Assembly.
  • Continuous Availability and Rapid Response: Maintain availability to address any security-related issues, responding immediately to identified or suspected security threats following notification.
  • Collaborative Problem-Solving and Support: Work with other Security Council members to resolve complex security threats, provide first-line support, and participate in "war room support" when escalated security issues arise. This includes participating in regular liveliness tests to ensure responsiveness.

These responsibilities ensure that the Security Council acts as a vigilant guardian of the technical aspects of the ZKsync ecosystem, maintaining its security, integrity, and proper governance.
