Arbitrum One on-chain state mapping: exists. It is the representative Optimistic Rollup Chain of inherited Arbitrum. Function: Provides a low-cost, high-throughput EVM execution environment and connects the economic activities of users and dApps with fee income. 2. Arbitrum Nova on-chain state mapping: Exists, but has different trust assumptions than Arbitrum One.
Arbitrum ARB is a mature layer two network, but the next security phase, sequencer distribution, and ARB value capture remain the tests.
Investment View
Arbitrum extends its L2 economy through BoLD, Stylus, Orbit, and DAO treasury depth, but app revenue and DAO capital efficiency must connect to ARB value.
