This meta-EIP specifies the changes included in the Ethereum hardfork that removes EIP-1283 from Constantinople.
Specification
Codename: Petersburg
Aliases: St. Petersfork, Peter’s Fork, Constantinople Fix
Activation:
Block >= 7_280_000 on the Ethereum Mainnet
Block >= 4_939_394 on the Ropsten testnet
Block >= 10_255_201 on the Kovan testnet
Block >= 4_321_234 on the Rinkeby testnet
Block >= 0 on the Görli testnet
Removed EIPs:
EIP-1283: Net gas metering for SSTORE without dirty maps
If Petersburg and Constantinople are applied at the same block, Petersburg takes precedence: with the net effect of EIP-1283 being disabled.
If Petersburg is defined with an earlier block number than Constantinople, then there is no immediate effect from the Petersburg fork. However, when Constantinople is later activated, EIP-1283 should be disabled.
