It’s being said that the Constantinople hard fork is a minor one. But as far I know, this is isn’t just a miner reduction fees. They are additional things which were implemented (like a special ꜱꜱᴛᴏʀᴇ case fee change which was later reverted).

So what’s the full set of changes and functionalities implemented by this latest hard fork ?

  • @Ismael the question you are talking about is about what was planned, and this question is what actually happened which isn’t the same thing. Commented Apr 10, 2019 at 16:28
  • @Ismael yet, the question you’re referencing is still about what was planned. And not everything happened as planned since. Commented Apr 10, 2019 at 16:42
  • @Ismael perfect. Commented Apr 10, 2019 at 17:07

  • EIP 1052: EXTCODEHASH Opcode
  • EIP 1234: Delay difficulty bomb, adjust block reward
  • EIP 1283: Net gas metering for SSTORE without dirty maps
  • May you detail the purpose of each change in your answer instead of just giving the links please ? Commented Apr 10, 2019 at 11:37
  • Each referred EIP has "Morivation" section. Do you want me to copy them into the answer? Commented Apr 10, 2019 at 11:44
  • This is rather a rule. Commented Apr 10, 2019 at 11:50
  • OK, the question was what is full change set. Full change set is listed in EIP-1013, so I gave a link to EIP-1013 and also copied the whole change list from EIP-1013 into the answer, thus obeying the rule. Commented Apr 10, 2019 at 11:53
