@/all Core devs meeting in a little less than 12 hours
Agenda for meeting: ethereum/pm#58
Videoconference Link: https://zoom.us/j/717504189
We will be having someone who has ran new benchmarks for EIP 1108: Reduce alt_bn128 precompile gas costs.
We will also be having the team behind ProgPoW on the call so we can all sync up with what various people have been doing to test, benchmark, and otherwise explore it.
Please look over EIP 1108 and think of any questions you have for the ProgPoW team.
Regarding some discussions that has been happening on EIp-1014, Skinny Create2.
I have now performed some benchmarks, and can confirm that the combination of uncapped size of initcode + lack of cost-per-byte is problematic in
CREATE2, and can lead to DoS attacks if not fixed. Therefore, I propose that we accept the change to EIp 1014 which uses the folowing phrasing:
Additionally, an extra
GSHA3WORD * ceil(len(init_code) / 32)gas is charged.
Furthermore the problem is also present today, with
CREATE, but that is due to internal implementation details in most (all?) clients. Short story: it can be fixed without changing
CREATE. Client implementors can PM me for details and testcases. I have already spoken to Parity members about this.
An alternative change could be to introduce a cap on initcode size. That would also 'fix' the problem in a less 'correct' manner. cc @/all
