Issues with the Aztlán protocol upgrades were identified and sufficiently patched with the Phoenix protocol upgrades. However, the subsequent activation of these upgrades on the Kotti and Mordor testnets revealed inconsistencies between client implementations. This document proposes a patch for the aforementioned testnets.
Abstract
The EIP-2200 defines structured definitions of net-gas metering for the
SSTOREopcode. This EIP was activated in a bundle called EIP-1679 "Istanbul" on the Ethereum Foundation network and ECIP-1061 "Aztlán" on the Ethereum Classic network.Notably, the difference here is that Istanbul contained EIP-1884 which repriced various opcodes for trie-size dependent operations, whereas Aztlán did not.
Both EIP-1884 and EIP-2200 propose the
SLOAD_GASto be increased from200to800but not all clients correctly implemented this change for both EIPs leaving networks configured with a pick-and-mix EIP configuration such as Aztlán with an incompatible configuration as compared to clients who correctly implemented the specifications.Motivation
This specification seeks to validate the incomplete configuration in favor of retaining the Kotti and Mordor testnets in consensus. This ECIP shall not be considered on mainnet. It's sole purpose is to allow avoiding a rollback on the testnets and having a proper documentation on the cause for the gas mismatch and providing instructions for client developers how to circumvent this.
