Sealevel

Also known asSVM Runtime

Solana's parallel transaction execution engine. Sealevel can process thousands of transactions simultaneously by analyzing each transaction's declared account inputs—transactions that don't touch the same writable accounts run in parallel across available CPU cores. This account-level parallelism is what enables Solana's high throughput.
