The development team further shared that their technical experiment plan includes activities to assess the capabilities of a coordinated response to security incidents in real-world conditions. It is expected that the knowledge gained from this comprehensive training will ultimately enhance the resilience of the Optimism network after the upgrade.
“An intriguing aspect of the upcoming update involves the introduction of a new SuperchainConfig contract. This contract is essential for improving the existing pause mechanism and providing more reliable asset protection. While currently minimalistic, the contract has the potential to expand over time as new features are added to the sidechain. This experiment will allow us to safely initiate a ‘wide pause,’ effectively halting the withdrawal of digital assets,” the message explains.
A “wide pause” in sidechains occurs when none of the superchain validators add a new block to the chain. This can be caused by various factors, such as network latency that hinders data synchronization or a lack of coordinated actions among participating validators during consensus.
It was previously reported that the second-layer solutions Optimism and Arbitrum for the Ethereum network are gaining popularity. In fact, the total number of transactions in these sidechains has already surpassed that of the main network.
