A champion is needed for
“It can be added to the Istanbul list if someone were to spend the time to champion it. It will also need to be updated with a section on new test vectors (likely just an update for the old ones) and a section on security considerations, since we are adjusting gas prices.”
Hi there!
AZTEC is quite interested in getting this EIP into Istanbul and we’re happy to try and push this forward. I’ve submitted a pull request to update the EIP and also to add it as a proposed EIP in eip-1679
Cheers,
Zac.
Original author of the EIP from Keep here, just to register support and thank Zac for picking up the baton here and filling in a bunch of details 
Please let me know if there’s anything I can do to help ensure EIP-1108 slots on in!
Thank you @zac-williamson and @Shadowfiend !!
It has been added to https://en.ethereum.wiki/roadmap/istanbul
@Shadowfiend @zac-williamson it seems @vbuterin proposed a similar reduction here. Can you put that as a reference into the EIP so that we can close the issue?
Done.
@zac-williamson I opened a PR for this on go-ethereum that I can move forward (https://github.com/ethereum/go-ethereum/pull/19904)—shall I take a crack at Parity as well or do you already have something cooking?
I have reviewed this EIP. Everything looks great, no reservations. Good work. I recommend for passage to Final.
