The Polygon Foundation announced that the Giugliano hard fork will be activated on the mainnet on April 8th, expected to occur at block height 85268500, around 14:00 UTC. This upgrade aims to improve network final confirmation speed by allowing earlier block broadcasts, introducing fee parameters in the block header, and adding RPC support for fee data. The upgrade was tested on the Amoy testnet last month, with data showing a reduction in final confirmation time of approximately 2 seconds. The official notice advises node operators to update Bor to v2.7.0 or Erigon to v3.5.0 before upgrading. This hard fork is part of Polygon's "Gigagas" expansion roadmap, focusing on improving network performance and user experience.
