Arbitrum vs Ink

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.

Ink is Kraken's Ethereum OP Stack Layer-2 built as a DeFi-focused member of the Optimism Superchain. It offers EVM compatibility, low fees and one-second blocks from launch, with sub-second blocks planned, so builders can deploy lending, DEX and yield applications close to Kraken's user base. No dedicated Ink token is mapped yet, so the blockchain is imported without an associated token.
