Optimism Takes Significant Step Towards Becoming Independent Ecosystem with Upgrade 20

The Optimism platform has taken a significant step towards becoming an independent ecosystem by implementing the Upgrade 20 protocol, which enables the network to more efficiently verify the state of its various chains.

This upgrade is not a hard fork of the L2 layer, but rather a modification to the smart contract on the L1 layer, allowing for better scalability and interoperability between Optimism-based chains.

The new protocol involves shifting the focus from block-specific verification to time-based verification, which will enable the creation of a shared system for managing the state of multiple Optimism-based chains.

The upgrade also includes an OPCM v8.0.0 update and various security and maintenance fixes.
