Overview
Arbitrum Nitro is a second-generation Layer 2 blockchain protocol. It provides high throughput, fast finality, and efficient dispute resolution. Nitro achieves these properties through several design principles: separating sequencing of transactions from deterministic execution; combining existing Ethereum emulation software with extensions to enable cross-chain functionalities; compiling separately for execution versus proving, so that execution is fast and proving is structured and machine-independent; and settling transaction results to the underlying Layer 1 chain using an optimistic rollup protocol based on interactive fraud proofs.
