# Gravity Reth: The Fastest Open-Source EVM Execution Client For EVM-based ecosystems, the execution client is a critical component of the system stack, often representing a significant performance bottleneck that limits on-chain throughput and raises transaction costs. While modern clients like Reth have made substantial strides in performance, their architectures are not primarily optimized for high-performance Layer 1s and Layer 2 roll-ups, which target sub-second finality and massive scalability, require a fundamental rethinking of client design to overcome bottlenecks in transaction execution, state commitment, and expensive I/O. We introduce Gravity Reth, an open-source, performance-engineered fork of Reth, designed to push the upper bounds of EVM execution speed. Through a suite of architectural innovations-including Grevm, a DAG-based optimistic parallel EVM; a fully parallelized merklization framework, a high-performance caching layer, an optimized mempool, and a pipelined execution architecture-Gravity Reth achieves state-of-the-art performance. _ERC20 Transfer Performance Comparison Across Different Account Scales_ In an ERC20 transfers benchmark across 100,000 accounts, Gravity Reth sustains ~41,000 transactions per second (TPS), equivalent to ~1.5 Gigagas/s. This represents a greater than 4x performance boost over the baseline `Reth 1.4.8` client. Our primary contributions are:
