This document test 3 layer2 chain, trying to find out their compatibility with ethereum. We use retesteth to test official Ethereum test vectors.

• retesteth : retesteth-0.2.3-postmerge+commit.c5274b17.Darwin.appleclang
• tests: https://github.com/ethereum/tests tag: v11.3
• opcodes: https://www.evm.codes/?fork=merge

follow the document: https://github.com/ethereum/retesteth to build retesteth then copy retesteth to /usr/local/bin

cp ./retesteth/build/retesteth/retesteth /usr/local/bin/retesteth

git clone https://github.com/unifra20/go-ethereum.git
cd go-ethereum
git checkout for_retesteth
make all
cd ..

unifra team have forked a repository from https://github.com/scroll-tech/go-ethereum.git based on prealpha-v5.1 and did some modifications to enable evm&t8ntool.

1. modified t8ntool to enable BaseFee and support the fork 'Merged'
2. change codehash algorithm from poseidon to Keccak256. Scroll team have done this in the latest branch.

sh ./runtest.sh scroll ./go-ethereum/build/bin/evm

We build a table show the result.

• folder: folder name
• total: total case count
• success: success case count
• fail: failed case but didn't known reason count
• known: failed and known reason
• rate: success/(total-known)

Most of the failed casees caused by SELFDESTRUCT,PREVRANDAO(DIFFICULTY).

These cases covered most of the evm opcodes. 136 opCode tested and there are 143 in total, basically coverage=95%

polygon team have published their test results:https://github.com/0xPolygonHermez

There is a list shows all ignored tests: https://github.com/0xPolygonHermez/zkevm-testvectors/blob/main/tools/ethereum-tests/no-exec.json

We see that DIFFICULTY, GASLIMIT, SELFDESTRUCT are ignored, they may have difference behavior between ethereum.

Optimism team released a document described optimism diffrence between ethereum, see: https://community.optimism.io/docs/developers/build/differences/#bedrock

According to this document, these opcodes COINBASE,DIFFICULTY,ORIGIN,CALLER may have differences between with ethereum.
