Can we add EIP-2456 to the discussion? At least as a springboard for a "are block based upgrade triggers the correct thing to do" discussion.

[shamatar]

EIP 1962 status:

• Rust and C++ implementations are complete feature wise
• Both arithmetic functions and gas estimation functions are fuzzy tested
• Moved to 10 separate “operations” that can be mapped to precompile addresses
• C-like API is exposed on demand with universal signatures for Rust and C++ implementations
• Go wrapper is on the way

What’s left:

• decide whether use single (Rust) or independent (e.g. Rust for Parity, wrapped C++ for Geth, etc) implementations
• make pipelines/builders for static libraries/go modules (would appreciate help with it) due to Rust and C++17 underneath
• what fuzzer to try next? Honggfuzz is fast and convenient (especially multicore!), but in a meantime it may be interesting to try e.g. AFL

Short note: there was a critical bug in our MuirGlacier EthereumJS VM release v4.1.2 preventing the VM to working properly when instantiated with the MuirGlacier HF. We just released a bugfix v4.1.3 release. An update is mandatory if you want a working installation.

[shemnon]

Also, EIP-2348, validated EVM contracts, as part of EFI review, but at the end as I feel the other two are more important. I added discussion points for two of the objections (transaction evm execution and why bytecode header) in the ethereum-magicians thread and would like to solicit responses.

@shamatar see https://github.com/ethereum/benchmarking/ -- that repo contians some old benchmarks for the crypto-precompiles

It also contains some analysis like https://github.com/ethereum/benchmarking/blob/master/analysis.md

[shamatar]

Thanks! I think that I’ll need to modify those scripts and run on my reference PC cause I use 4 threads (for 6 physical cores) during generation of the test vectors, so CPU frequency is not on the maximum (Intel CPU frequency management)

Closing in favor of #148.
