@ethereumjs/evm v2.1.0

New EVM Profiler / EVM Performance

This releases ships with a completely new dedicated EVM profiler (❤️ to Jochem for the integration) to measure how the different opcode implementations are doing, see PR #2988, #3011, #3013 and #3041.

See the new dedicated README section for a detailed usage instruction.

We were already able to do various performance related improvements using this tool (and we hope that you will be too) 🤩:

• Substantial stack optimizations (PUSH and POPn +30-40%, DUP +40%), PR #3000
• JUMPDEST optimizations, PR #3000
• Various EVM interpreter optimizations (overall 7-15% performance gain), PR #2996
• Memory optimizations (MLOAD and MSTORE + 10-20%), PR #3032
• Reused BigInts cache, PR #3034 and #3050
• EXP opcode optimizations (real-world 3x gain, not attack resistant), PR #3034

EIP-7516 BLOBBASEFEE Opcode

@ethereumjs/client v0.9.0

This client release now syncs with the new Holesky and Dencun devnet-11 test networks and comes with improved sync performance, a revamped post-Merge client UX experience and various beacon sync related fixes and robustness improvements.

Holesky Testnet Support

This client release now fully supports running the new Holesky public Ethereum testnet replacing the Goerli test network, see , PR #2982 and some following PRs.

The following command starts an EthereumJS client on Holesky:

ethereumjs --network=holesky --rpc --rpcEngine

Then start a corresponding CL client (e.g. Lodestar with checkpoint sync towards https://lodestar-holesky.chainsafe.io), also see client README.

Dencun devnet-11 Compatibility

Another testnet to be run with this client: Dencun devnet-11, which is one of the last and eventually the very last testnet before running the Dencun hardfork on the official testnet.

Following spec updates included:

• Update EIP-4788: do not use precompile anymore but use the pre-deployed bytecode, PR #2955
• Additional EIP-4788 updates (address + modulus), PR #3068
• Update the beacon block root contract address, PR #3003
• Fix newPayloadV2 having PayloadV3 params, PR #2954
• Include parent beacon block root for proposal payload uniquness, PR #2967
• Fixes for new engine api method validations for hive pr-834, PR #2973
• Track and respond to invalid blocks in engine api and other hive engine-cancun fixes, PR #3077
• Make the newpayload execution of big blocks non blocking, PR #3076
• Hive Cancun fixes, PR #3099

See devnet-11 EthPandaOps GitHub repository for instructions on how to run the testnet.

Sync and EVM/VM (Execution) Performance

This client release integrates with the EthereumJS EVM v2.1.0 (see EVM CHANGELOG for details) which comes with significant performance improvements for various opcodes as well as overall EVM execution.

Furthermore the data model for saving the state has been optimized to improve storage DB read performance, see PR #3023 and PR #3067.

Both changes together should increase client sync performance by 30% or more.

Important: The new db model is not backwards-compatible with existing client databases. Use the new --prefixStorageTrieKeys (set it to false) and --useStringValueTrieDB (set it to true) flags to preserve the old DB behavior.

New Post-Merge UX Experience

We have gone through the complete post-Merge beacon sync process and reworked the client output along, see PR #3085 and some follow-up PRs. It is now substantially easier to follow the different stages of the sync process (backfilling, forwardfilling & execution, following the chain) and track the overall sync progress. Holesky with its newly initialized state is a great testbed to see the new client capabilities in practice! 🤩

Block/Tx Profiling

The client can be now leveraged as a tool for block and/or tx profiling by using the new --vmProfileBlocks and --vmProfileTxs options, see PR #3042. This gives details into the EVM/VM execution performance for specific blocks. See profiler related EVM README section for further details.

Discovery Improvements

A new more fine-tuned discovery discV4 mechanism has been integrated along PR #3120. This should now make it substantially easier to find new peers especially on smaller networks like the devnet-11 and related Dencun test networks. Additionally the --bootnodes option has been expanded to now also take bootnode.txt files for easier loading of bootnodes.
