BlockBeats News, March 5 — According to official sources, Optimism announced that support for op-geth and op-program will end on May 31, 2026. During this period, security patches and critical vulnerability fixes will still be released, but new feature development, including the next Karst hard fork, will only be carried out on op-reth. The fault proof program for op-program will also be migrated to kona-client, which is currently expected to remain usable until before the Karst hard fork.
Network operators must complete the migration at the time of the Karst hard fork; otherwise, chains still running op-geth will not be able to follow the main chain. cannon-kona can run in the existing op-node environment without using kona-node, as kona-node is an optional component. Node operators should migrate to op-reth as soon as possible to maintain network compatibility and access new features.
