| # EOF | ||
|
|
||
| ## Overview | ||
|
|
||
| The Ethereum Object Format (EOF) represents a transformative update to the Ethereum Virtual Machine (EVM) bytecode structure. Designed to enhance the efficiency, security, and modularity of smart contracts, EOF restructures how smart contract bytecode is organized. This upgrade addresses traditional limitations of the bytecode format, aiming to make contracts more manageable and secure. | ||

| ## Meeting info | ||
|
|
||
| Date: 2024.7.24 | ||
|
|
||
| Agenda: https://github.com/ethereum/pm/issues/1115 | ||

|
|
||
| ## Notes | ||
|
|
||
| ### Client updates | ||
|
|
||
| Discussed EOF container validation | ||
|
|
||
| some discussion about testing | ||
|
|
||
| ### Compiler | ||
|
|
||
| need to finalize solidity PR (depends on an evmone release w/ EOF) | ||
|
|
||
| ### Spec | ||
|
|
||
| Contract Detection | ||
| - Contracts can either disable safetransferfrom, or call out to another contract with legacy features to get the "isContract" question answered. | ||
| - "do nothing" is the most undoable, as we can add ISCONTRACT later. But we cannot do the return code changes. | ||
| - do nothing / fix later has momentum | ||
|
|
||
| Tracing changes | ||
| - There was discussion of process | ||
| - PC is zero to section | ||
| - Maybe shorter names for section | ||
| - Danno will write up a new EIP as a red herring, rather than modify 3155 | ||
| - goEVM lab wants nomemory and nostack options (maybe just top of stack). Make this the default? | ||
|
|
||
| ### Testing | ||
|
|
||
| Instead of Kurtosis we can use EEST consume | ||
| - Kurtosis's main gain is it's a full client setup | ||
| - EOF calls to the system contract would be valuable in Kurtosis. Withdrawals/deposts/other pectra calls | ||
| - Not valuable at the moment | ||
|
|
||
| Run every test via consume | ||
|
|
||
| EEST could produce Assertoors | ||
|
|
||
| Testing blindspots | ||
| - Need to update the checklist | ||
| - Quantify the testing progress for next ACDE | ||
| - Make sure all EIPs tests are in the testing checklist | ||
|
|
||
| Devnet | ||
| - We want fuzzing ready | ||
| - Do we need to be 100% for devnet? | ||
| - Client should pass fuzzing | ||
| - Clients should pass reference tests at 100% (EESTs and Ethereum/tests and evmone) | ||
| - 7702 will be dominating devnet testing | ||
| - Reth and Besu can join a devnet today (configuration wise) | ||
| - Need updates from Geth, Nethermind, EthJS, Erigon |

| ## Meeting info | ||
|
|
||
| **Date**: 2024.08.21 | ||
|
|
||
| **Agenda**: https://github.com/ethereum/pm/issues/1128 | ||

|
|
||
| ## Notes | ||
|
|
||
| ### Client and fuzzing updates | ||
|
|
||
| evmone found a bug that fuzzers couldn't find | ||
|
|
||
| besu had subcontainer container bugs found via evmon's tests a few weeks ago | ||
|
|
||
| Nethermind is re-writing their subcontainer validation to not be recursive | ||
|
|
||
| Reth and Geth were not present. | ||
|
|
||
| ### Spec updates | ||
|
|
||
| community strongly wants a EXTCODESIZE/ISCONTRACT solution, Libs may not be happy with legacy "escape hatch" contracts rather than using EIP-165 introspections | ||
| - If AA is the reason not to proceed, a clear plan needs to be stated as to how the AA transition is expected to play out. | ||
|
|
||
| Delegate call into legacy call rule | ||
| - This may break proxies. (EOF proxies, proxying to a legacy contract) | ||
| - A detection of EOF vs legacy contract would be useful. EXTCODEHASH would identify EOF | ||
| - No opinion about 7702 proxy detection detection, can go with legacy treatment. | ||
|
|
||
|
|
||
| ### Testing Readiness | ||
|
|
||
| With devnet-4 we need to activate on prague alone | ||
| - EEST will migrate to just "Prague" for tests, | ||
| - EEST will sunset "CancunEIP7692" and "Prague7692" forks | ||
| - Will change once 7702 tests are fully merged into tests | ||
| - Suddenly 7702 tests will work with EOF | ||
|
|
||
| New fixtures release 1.0.8 - Contains Both pragueEIP-7692 and Cancun7692 | ||
|
|
||
| EOF Container Fuzzing | ||
| - EVMONE and Besu | ||
|
|
||
| EOF Execution fuzzing | ||
| - possibly goevmlab, guido vranken's fuzzer. | ||
|
|
||
|
|
||
| ### Testing matrix | ||
|
|
||
| Devs, please update | ||
|
|
||
| Any automation interest? | ||
| - Maybe hive/consume? | ||
| - Still needs final consume setup in CI | ||
| - Consume does not run EOF Validation tests (because engine API is the test interface) |
