Ethereum Layer 2 network Optimism will release Bedrock, its first major upgrade, on Mar. 16, with the goal of improving network performance.

The upgrade will enable improvements in transaction costs, speeds, and compatibility with the Ethereum Virtual Machine. In addition to these performance enhancements, the upgrade will also create a foundation for future improvements, such as decentralizing sequencing — the part that collates the transactions together — and improving on-chain security. Sequencing allows the network to derive security from Ethereum.

The team at Optimism stated that the majority of users will not be impacted by the upgrade. However, users and projects that run full nodes will need to take action to prepare for the upgrade.

The team estimates that the upgrade to Bedrock will take less than four hours and will not require a network reset, also known as “regenesis.” Historic chain data will still be accessible after the upgrade, ensuring that users will not lose any important information. The Optimism Goerli testnet has already successfully upgraded to Bedrock.
