Agenda

1. Istanbul EIPs go/no-go
   • EIP 1344

Is the meeting date/time correct?

[timbeiko]

@fubuloubu it wasn't. Thanks for the catch! Updated.

Results and points for EIP1962:

• Separate into 7 precompiles for corresponding operations (proposed by @shemnon), need developers consensus on what can be called "standard practice" for it
• Fuzzy testing on 32 core machine over 6 days, 16M iterations per hour. Found few mistakes, but those were parsing related. Will result in making Rust implementation ABI parser more in style of stateful parser from C++ for convenience
• Proposal for Istanbul:
  • Use universal codebase and universal gas metering policy
  • Whitelist 7 pairing friendly curves for use with "Pairing" and "G2*" operations. Those can be easily whitelisted by comparing first 100 bytes in the input. "G2" ops do not contain non-trivial edge cases compared to "G1_", but are useless on non-pairings curves, so can be whitelisted too
  • Keep "G1_*" operations universal for any curve. Those have only 1 possible edge case in arithmetic and it's covered

@holiman can we get some discussion/decision on EIP-1884?
