Ethereum is embracing the Constantinople milestone at the end of November 2018, after DevCon4 in Prague. Constantinople is the latest Ethereum release, introduced through a hard fork, that will include five Ethereum Improvement Proposals (EIPs):

  • Bitwise shifting instructions (EIP 145) in the Ethereum Virtual Machine (EVM) allow for direct manipulation of bytes on the EVM layer.
  • Skinny CREATE2 (EIP 1014) adds a new opcode that creates a contract but determines the deployed address differently to the existing CREATE opcode.
  • The EXTCODEHASH opcode (EIP 1052) adds an opcode which returns the keccak256 hash of a contact’s byte code.
  • Net gas metering for SSTORE (EIP 1283) introduces a new gas cost scheme for the SSTORE opcode.
  • The difficulty bomb delay (EIP 1234) stabilizes block times and issuance by keeping block times at approximately 15 seconds for another 12 months and reducing block rewards to 2 ETH.

To the regular application user, these updates offer nothing noticeably different,…
