MegaETH Technical Details

MegaETH stands out as a Layer-2 solution built on Ethereum, claiming to be a “real-time blockchain.” Its aim is to offer low latency and high transaction speed at the Web2 level while maintaining Ethereum’s security and EVM compatibility.
Key Performance Targets
Block time: ~10 ms (milliseconds) – some sources aim for sub-10 ms
Transaction capacity (TPS): 100,000+ TPS target (values between 15,000–50,000 TPS were reported in tests during the mainnet launch)
Gas throughput: 10+ Ggas/s (10 billion gases per second)
EVM compatibility: Fully Ethereum Virtual Machine compatible
Main Architectural Features
🔹Heterogeneous / Specialized Node Design (Node Specialization)
MegaETH does not want every node to do the same job. Different hardware requirements are defined for different roles.
🔹SALT (Small Authentication Large Trie)
One of MegaETH's most important innovations. A special state design that keeps the entire authentication structure in RAM to eliminate the disk I/O bottleneck of traditional state tries. This allows the sequencer to approach the speed of a central database.
🔹Just-In-Time (JIT) Compilation
A JIT compiler is used that runs the EVM bytecode at almost native speed.
🔹Mini-blocks & Parallel Execution
Very small blocks (mini-blocks) are generated and operations are processed in parallel. This makes block times of 10 ms possible. 🔹Modular Structure & Settlement
Settlement: On Ethereum L1
Data Availability: EigenDA is used
Based on Ethereum security with the Optimistic Rollup model
🔹Stateless Validation & Lightweight Validation
Stateless validation and witness mechanisms are used so that prover nodes can run on very low hardware. This allows the network to be open to more participants while maintaining high throughput.
