ZkSync: The zkSync Era implementation delay security mechanism will allow sufficient time to detect issues and react in a timely manner

On March 24th, zkSync introduced one of the multi-layer security mechanisms of zkSync Era, namely, execution delay. Execution delay means that each L2 block submitted to L1 will have a time lock before execution and final determination. The initial delay will be 24 hours. As the system matures, the delay will gradually decrease until the alpha phase is removed, at which time the delay will be completely removed. The main purpose of the delay is to ensure that the team has sufficient time to verify the impact of transactions included in the block before the block becomes the final block, and has sufficient time to detect vulnerabilities, investigate, and pass governance freeze agreements.

# On March 24th, zkSync Introduced Execution Delay: A Multi-Layer Security Mechanism to Ensure System Security
The zkSync Era has introduced a new security mechanism called execution delay, which introduces a time lock before the execution and final determination of each L2 block submitted to L1. The initial delay has been set to 24 hours, but will be gradually decreased as the system matures. At the alpha phase, the delay will be completely removed.
# What is Execution Delay in zkSync?
Execution delay is a security mechanism that ensures the team has enough time to verify the impact of transactions included in the block before the block becomes the final block. This additional time allows team members to detect vulnerabilities, investigate, and pass governance freeze agreements, if necessary. The main goal of the execution delay mechanism is to ensure that the system is secure and to reduce the possibility of fraud and hacking.
The mechanics of execution delay are straightforward. Each L2 block submitted to L1 will have a time lock before execution and final determination. During this period, the team will have the opportunity to investigate and verify the transactions before the block becomes the final block.
# Why is Execution Delay Important?
Execution delay is vital because it provides additional security to the zkSync system. First, the delay ensures the system’s security by allowing the team to investigate vulnerabilities and detect any fraudulent activity before the block becomes the final block. Second, the delay provides enough time for governance freeze agreements to pass. In doing so, the team ensures that the system can quickly respond to potential security threats.
# The Future of Execution Delay in zkSync
The timing of execution delay is expected to decrease as the system matures. This decrease will provide users with a more efficient system while maintaining the necessary security. Additionally, additional security measures are being considered, which will provide even greater protection for users of the zkSync system.
# Conclusion
Execution delay is a powerful security feature that has been added to the zkSync system. This feature provides additional security against fraud and hacking, ensures the system’s security, and allows the team to respond to potential security threats quickly. As the system matures, the timing of the delay will decrease, providing even greater benefits to users. As supporters of the zkSync system, we must continue to support these critical security developments.
# FAQs
1. Why was execution delay added to the zkSync system?
Execution delay was added to provide additional security to the system and allow the team time to verify transactions before they become final.
2. How does execution delay work?
Each L2 block submitted to L1 will have a time lock before execution, allowing the team to investigate and verify transactions before the block becomes the final block.
3. Will the timing of the execution delay change in the future?
Yes, as the system matures, the timing of the delay will decrease, providing users with a more efficient system while maintaining necessary security.
