Optimism is set to implement on Tuesday its “Bedrock” upgrade, designed to improve the usability of the chain by lowering gas fees and cutting deposit-confirmation times by 90%.
Bedrock aims to lower gas fees by 40% by implementing “an optimized data compression strategy,” and will introduce support for reorgs, which is when a blockchain produces two blocks at the same time and it temporarily creates a duplicate blockchain. The code change in Bedrock will mitigate reorgs by reducing confirmations for deposits to 1 minute from 10 minutes.
The upgrade will also improve proof modularity for its OP Stack as well as introduce other code changes that will improve node performance. Improvements to proof modularity means that after the upgrade, validity proofs and fault proofs can both be used with the OP Stack.
In addition, Bedrock will help move Optimism to a multi-client ecosystem, meaning there would be at least two versions of software used to interact with the network. Client software is used to run the blockchain, and layer 1 blockchains like Ethereum rely on multiple clients to help maintain the security of the network. If there’s a bug in one client, then the chain can rely on other clients to keep the blockchain running.
