Arbitrum vs NEAR Protocol FAQ
- What is Arbitrum?
- Arbitrum is an optimistic rollup on Ethereum built by Offchain Labs. Mainnet launched August 2021 as Arbitrum One; a second chain — Arbitrum Nova — targets gaming/social with AnyTrust data availability. By early 2026 it is consistently the largest L2 by TVL, rivalled only by Base.
- What does "optimistic rollup" mean?
- Transactions posted to L1 are assumed valid by default. A 7-day challenge window lets any watcher submit a fraud proof to revert fraudulent batches. The sequencer (currently centralised, operated by Offchain Labs) orders transactions; decentralising it is on the roadmap. Security ultimately inherits from Ethereum.
- What is NEAR Protocol?
- NEAR (NEAR) is a proof-of-stake Layer 1 launched in 2020, designed for usability: human-readable account names (alice.near), built-in account abstraction, and Nightshade sharding for horizontal scaling. Contracts are in Rust or AssemblyScript, not Solidity.
- What's Chain Signatures?
- A NEAR primitive that lets NEAR smart contracts sign transactions on other blockchains via threshold cryptography. It powers cross-chain AI agents, multi-chain wallets, and Bitcoin on NEAR without bridges. Launched in 2024, it's one of NEAR's most differentiated features.
- How do Arbitrum and NEAR Protocol compare?
- Arbitrum (ARB): Largest Ethereum L2 by TVL. Optimistic rollup, Stylus (Rust) support. Launched 2021, runs Optimistic Rollup (Ethereum L2). NEAR Protocol (NEAR): Sharded Layer 1 with human-readable accounts. Chain Signatures for cross-chain. Launched 2020, runs Nightshade Proof-of-Stake.
