Optimism completes upgrade of its Layer 2 network

Optimism has completed its major Bedrock upgrade, a ground-up overhaul of the OP Mainnet Layer 2 protocol designed to make the network more modular, cheaper, and more closely aligned with Ethereum’s architecture. Bedrock restructures Optimism as a set of components built on the open-source OP Stack, aimed at standardizing how Optimism and other chains in its ecosystem implement rollup functionality. This upgrade is positioned as a foundational step for an ecosystem of multiple Layer 2 chains that share common infrastructure while inheriting Ethereum-grade security. Technically, Bedrock introduces a more Ethereum-equivalent execution environment, refined data compression and batching for rollups, and a redesigned deposit/withdrawal pipeline, which together are intended to significantly reduce transaction fees and improve confirmation times compared to the previous Optimism implementation. By moving to this modular, OP Stack-based design, Optimism aims to support a broader “Superchain” of interoperable L2s, making it easier for other projects to launch their own rollups that plug into the same shared framework and governance model. For developers and users, the upgrade matters because it seeks to provide lower costs, more predictable performance, and a more Ethereum-like developer experience, while laying the groundwork for a larger network of Optimism-aligned chains.
