Entry points for information:

• EIP-1679 Meta EIP (canonical source)
• EthHub Istanbul Roadmap

EIP Working List:

• EIP-152: Blake 2b F precompile

  • Common: Update price params, Add missing Istanbul gas costs  ethereumjs-common#58
• EIP-1108: Reduce alt_bn128 precompile gas costs
  • Common: Istanbul integration, add updated gas costs, New release v1.2.1 (added draft EIP-1108 alt_bn128 gas costs) ethereumjs-common#53
  • VM: Update on new Common version, Istanbul Draft EIP-1108 Support #540
• EIP-1344: Add ChainID Opcode
  • VM: Add Opcode, [Istanbul] EIP-1344: Add ChainID opcode #569, PR Add CHAINID opcode for istanbul (eip-1344) #572

  • Common: Update price params, Add missing Istanbul gas costs  ethereumjs-common#58
• EIP-2200: Rebalance net-metered SSTORE gas costs with consideration of SLOAD gas cost change (still the most discussed PR, follow discussion closely, see EIP PR thread or e.g. this comment on ACD Gitter channel)
  • VM: Eventually some of the old Constantinople implementation at EIP 1283 SSTORE #367 can be reused, see also tests at SSTORE Test Coverage #502, PR Istanbul: EIP-2200 net gas metering for SSTORE #590
  • Common: Price updates, Add EIP-2200 gas parameters for Istanbul ethereumjs-common#65

Other TODOs:

• Update ethereumjs-testing with Istanbul tests once substantial test parts are merged, e.g. Istanbul holiman ethereum/tests#627

We should as time/decisions progresses create separate issues for accepted EIPs and discuss implementation details there.

On the last ACD call it was decided that https://eips.ethereum.org/EIPS/eip-1679 is the canonical source of information for proposed EIPs. It should be enough to follow that.

@axic Ah ok, thanks!

Grabbed this Istanbul EIP Readiness Checklist from the EIP Gitter channel, super-detailed and helpful.

Still not 100% sure on the process though and what EIPs will finally be included. As far as I got comments from @bmann on ACD Gitter, there seems to be the need for a reference implementation of an EIP to be included, not sure if there also needs to be a final ok from ACD call and if there is/will be some general limitation in scope at some point to not overload.

I would suggest we start with some low-level stuff from the spreadsheet, this opcode renaming EIP-1803 has made it pretty far and will likely be included, since it wouldn't make sense to postpone such a trivial change.

Will open an issue on that so that we get the process going.

We are now starting Istanbul integration, just to let you know. I would suggest you follow the process a bit and start early on with a draft integration so that users can early on start to experiment with new features. This will take an important role in helping to prevent such a chaotic last-minute situation as happened during along the last Constantinople/Petersburg hardfork 😛.

We are also very close on merging the TypeScript transition work from @s1na here #479 into master and will publish a beta v4 release on this during next week. This is also coming with heavy internal changes, the outer API stays unchanged though for now. The inner structure is not completely finalized and will likely further change to some extend on the way towards a final release. You are very much invited to have a look, do your thoughts on that and hook into the process.

If you have any questions on Istanbul respectively v4 let us know! 😄
