The update affects Mainnet node operators responsible for keeping infrastructure aligned with the network’s protocol sequence. It follows the earlier Protocol 24 stage and means network participation now depends on completing the next required node upgrade within the new timeline.
The next point to watch is whether Pi Core Team confirms completion before or after June 18. For now, Protocol 25 remains an active upgrade requirement, not a confirmed final rollout.
