A new Ethereum hard fork is coming

By Marco Cavicchioli - 30 Jul 2018

Chevron down

Constantinople is the name of the next Ethereum hard fork. No date has yet been set, but developers are already developing and testing the code.

It was planned for the second week of October, although, after the All Core Dev Meeting #42 on 13 July, the implementation might have been postponed until January 2019.

In any case, the final decision is planned for the next All Core Dev Meeting #43.

The goal of the fork is to make the Ethereum network cheaper and more efficient, following the path started with the previous fork, Byzantium, which took place last October 2017.

This requires a lot of work, so the development and testing process will not be rapid.

Constantinople will be a hard fork, which means that the new protocol will not be compatible with the current one, so the developers are proceeding very carefully.

In this regard, in order to better manage any unexpected event, the proposed roadmap is flexible: the implementation phase will last until August 13, followed by two months of testing, including the launch of a specific testnet.

The update foresees several optimizations to the Ethereum network, such as the very low transaction costs.

Fork technicalities

In total, the fork implements five EIPs (Ethereum Improvement Proposals):

  • EIP 145: Bitwise shifting instructions in EVM, which adds two bit-for-bit (SHL s SAR) operators to the EVM;
  • EIP 210: Blockhash refactoring
  • EIP 1014: Skinny CREATE2
  • EIP 1052: EXTCODEHASH Opcode adds the EXTCODEHASH opcode which allows contracts to calculate the keccak256 hash of the bytecode of other contracts;
  • EIP 1087: Net gas metering for SSTORE operations, which allows consuming less gas.
