Tech & Launches ·
Polygon has scheduled the Ithaca hardfork for July 20 on the testnet Amoy and July 29 on mainnet, according to an announcement by the Polygon Foundation. The upgrade aims to rotate stalled block producers within the network's validator set.
The hardfork represents a protocol-level change intended to address validator performance issues by cycling out producers that have stalled. This mechanism helps maintain network health and validator participation across Polygon's proof-of-stake consensus layer.
The staggered rollout—first to testnet, then to mainnet roughly nine days later—follows standard upgrade practice, allowing developers and validators time to test the changes before broader deployment. No additional technical details about the rotation mechanism or criteria for identifying stalled producers have been disclosed in available announcements.
