Erigon and Nethermind Join Arbitrum

Arbitrum is expanding its technical foundation by integrating two new execution clients—Erigon and Nethermind—alongside its existing Nitro client. This strategic diversification enhances decentralization, reduces reliance on a single codebase, and unlocks new performance and infrastructure efficiencies across the network.

Key Ideas

Multi-client architecture boosts resilience and performance: Nethermind delivers high-speed syncing and optimized RPC throughput for demanding applications, while Erigon slashes storage requirements, enabling lightweight archival nodes and broader participation.
Tailored benefits for builders and operators: developers can fine-tune dApps to match client strengths (e.g. Nethermind for speed, Erigon for storage), while entrepreneurs gain flexibility to deploy infrastructure that balances cost, reliability, and scalability.
