Versioning of the VM - does it make it into Istanbul

There are several outstanding EIPs covering different versions of this. See also https://ethereum-magicians.org/t/evm-instruction-set-versioning/2286. @sorpaas did a presentation on this topic in Berlin a few days ago, we should link to his slides or video of his talk here.

The slides are here (source, direct download link). EIPs covered in the talk include:

• EIP-1702: https://eips.ethereum.org/EIPS/eip-1702
• EIP-1707: EIP-1707: Use Version Byte Prefix for Contract Account Versioning ethereum/EIPs#1707 (also Issue #154)
• EIP-1712: EIP-1712: Disallow Deployment of Unused Opcodes ethereum/EIPs#1712
• EIP-1891: EIP-1891: Contract-based Account Versioning ethereum/EIPs#1891

It feels like currently the most promising one is EIP-1702 (including the "Alternative Design" section).

The one in Ethereum Magicians looks to me like a variation of EIP-1707 / Issue #154 thus suffers the same problem (i.e. we'll either break "minor" backward compatibility continuously, or break backward compatibility for one last time by combining it with EIP-1712).

Thanks Wei! This is amazing!

@sorpaas is there a reason you haven't submitted any of these for Istanbul yet? What would that take? CC @axic @cdetrio

[cdetrio]

What do you mean by "submit for Istanbul"?

[lrettig]

It's not on the list of EIPs proposed for Istanbul: https://github.com/ethereum-cat-herders/PM/blob/master/Hard%20Fork%20Planning%20and%20Coordination/IstanbulHFEIPs.md or https://en.ethereum.wiki/roadmap/istanbul

Since we have an update to 233, PRs to 1679 would be the next step. Everything else is nice to have for informative / tracking.

I’ll update the wiki to make that clear.

[sorpaas]

@lrettig @bmann I created PR #63. Let me know if there's anything else I need to do at this moment.

[bmann]

@sorpaas sorry but it needs to be PRd into 1679 https://eips.ethereum.org/EIPS/eip-1679

@lrettig this list in ECH is causing confusion. I think tracking issues on the Istanbul GitHub project would be super useful but a Markdown file that isn’t in sync with 1679 is wasted effort.

[bmann]

@lrettig @poojaranjan have a look at the project board here https://github.com/orgs/ethereum-cat-herders/projects/2 -- ideally this is something ECH can review on a weekly basis and keep things moving.

OK, marking this as closed.
