MegaETH architecture: single sequencer, in-memory state and JIT compilation
Quote113 words
Explains MegaETH as a validity rollup on EigenDA with a single sequencer, in-memory computation (about 1000x faster state access), parallel streaming execution publishing state every 10ms, JIT EVM compilation and a custom state trie.
Key claims
Over 100k TPS and under $0.01 tx fees
In-memory computing cuts state access latency by about 1000x vs disk
State published every 10ms
MegaETH is not your average rollup.
MegaETH is built different.
TL;DR ↓
→ Validity rollup using EigenDA, achieving >100k TPS, <1ms latency, and <$0.01 tx fees.
→ Single-sequencer architecture that eliminates consensus overhead where full nodes verify state via cryptographic proofs without tx re-execution.
→ Sequencer nodes optimized with in-memory computing, reducing state access latency by ~1000x vs. disk-based systems.
→ Real-time parallel transaction execution with streaming concurrency control and prioritization, publishing state every 10ms.
→ Just-in-time (JIT) compilation translates EVM bytecode directly to machine code, removing interpreter overhead.
→ Custom-built state trie minimizes disk I/O bottlenecks, efficiently scaling to terabytes of state data while preserving EVM compatibility.
