SP1 Reth

SP1 Reth is a 100% open-source POC that showcases how any rollup can use SP1 to build a performant (type-1, bytecode compatible) zkEVM with less than 2000 lines of maintainable Rust code. SP1 Reth achieves incredible performance (around $0.01-0.02 proving cost for an average Ethereum transaction) by leveraging SP1’s open-source, customizable precompile system, with orders of magnitude improvements to come. SP1 Reth points to a future where all rollups can become ZK rollups, utilizing the magic of ZKPs with maintainable software written in Rust.

Requirements

To reproduce the benchmarks in our blog post, your system will need:

• 64+ CPUs
• 512+ GB RAM
• NVME Hard Drive

We ran our benchmarks on a i4g.16xlarge instance on AWS. You may need to add a swap file on NVME.

Run

Make sure you have mounted your NVME hard drive in a RAID0 setup with at raid0 with a tmp folder.

cd script
TMPDIR=/mnt/raid0/tmp \
SHARD_SIZE=524288 \
RUST_LOG="debug,p3_keccak_air=off" \
RUSTFLAGS="-C target-cpu=native" \
cargo run --release -- \
  --rpc-url <rpc_url> \
  --block-number <block_number>

Security

This code has not yet been audited, and should not be used in any production systems.

Acknowledgements

We would like to acknowledge the projects below whose previous work has been instrumental in making this project a reality:

• Reth: For providing an excellent execution client reference and primitives needed for processing blocks.
• Revm: For providing core execution primitives and a performant EVM implementation.
• Alloy: For providing core ethereum primitives and RPC methods.
• Zeth: For providing a performant MPT library that can be compiled inside the zkVM and a reference for how to perform preflight/postflight execution logic. We chose to not fork Zeth directly because we noticed there was an opportunity to reuse significantly more code from Reth, Revm, and Alloy.
