Optimism announced that the Canyon hard fork has been successfully activated on the testnet. It is reported that the Canyon upgrade includes Shanghai and Capella hard fork support and the repair of some minor bugs. Canyon also made some specific adjustments to the OP Stack. This upgrade will increase the denominator of EIP-1559 from 50 to 250 to reduce the rate at which the block basefee rises when the gas target is exceeded. Users will not be affected by this testnet upgrade. Node operators will need to upgrade their nodes after the Canyon upgrade.
