         Abstract
      
      
    


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.

	The list above includes the EIPs that had to be removed from Constantinople due to a potential reentrancy attack vector. Removing this was agreed upon at the All-Core-Devs call #53 in January 2019.
