Arbitrum vs Gnosis

Arbitrum One and Nova are optimistic rollups using Nitro fraud proofs that compress transactions into calldata submitted to Ethereum. The Orbit toolkit lets projects deploy their own Arbitrum Orbit chains with configurable permissions. ARB token governance manages the 3 000‑plus validator whitelist and a 1 billion‑dollar ecosystem grant fund.

Gnosis Chain is an Ethereum sidechain prioritizing low fees, decentralization, and community governance. It runs with $0.0001 per 100k gas costs, 5-second block times, and a globally distributed validator set exceeding 350k nodes. Through GnosisDAO, stakers use the GNO token to secure the network and vote on on-chain proposals shaping the chain’s future.
