EIP-1716 is a meta-proposal that outlines the changes included in the Ethereum hardfork called Petersburg. This hardfork removes EIP-1283 from the previous hardfork called Constantinople. The activation block for Petersburg is set at Block >= 7_280_000 on the Ethereum Mainnet. The removed EIP-1283 was related to net gas metering for SSTORE without dirty maps and was removed due to a potential reentrancy attack vector. If Petersburg and Constantinople are applied at the same block, Petersburg takes precedence and EIP-1283 is disabled. The proposal was agreed upon at the All-Core-Devs call #53 in January 2019.

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.
