ZKsync

Matter Labs develops ZKsync in the open and governance runs through the Token Assembly, Security Council and Guardians. In 2026 the Security Council executed five instant upgrades to patch flaws in the proof circuits before disclosure, and on 4 September 2026 the team announced five security measures and a move to a 24-hour execution delay. The response is disciplined, but the number of flaws is a weakness.
