zkSync Overcomes zkSync Era Issue with Swift Bug Resolution

The project team swiftly acknowledged the zkSync Era issue, assuring users that funds were never compromised and committed to a prompt resolution.

Upon investigation, the team identified a subtle bug related to state updates within the protocol. While the computations made by the protocol were accurate, an oversight in how the operator computed them triggered a defensive response in the network. This defensive posture, established over a year ago in preparation for the Era mainnet launch, proved crucial in maintaining the system’s integrity during the incident.

The bug was promptly addressed, and the sequencer resumed processing transactions, clearing the backlog that had accumulated during the disruption. To prevent similar occurrences, an updated version of the node software was swiftly released for other node operators to implement.

It’s noteworthy that a similar halt occurred in Arbitrum, another Layer-2 solution, just 10 days before the zkSync Era issue. Both interruptions were attributed to inscriptions, emphasizing the need for continual vigilance in the evolving landscape of blockchain technology.

zkSync reassures its user base that the maximally defensive posture, once deemed suitable for the system’s launch, is now under review due to the platform’s enhanced maturity. As the team remains committed to the security and stability of the network, users can expect ongoing improvements to prevent future disruptions.
