Strengths and weaknesses
Pros	Secured over $12.3B in value with 2.7 billion lifetime transactions by mid-2026 Supports smart contracts in Rust, C, and C++ alongside standard EVM Solidity Fast sub-second block times around 0.25 seconds with gas settled in ETH	One-time upfront fee for permanent decentralized data storage Proof of Access consensus rewards nodes for preserving historical archives AO Computer enables parallel computing on top of immutable storage
Cons	Sequencer remains centralized, creating liveness and transaction ordering dependencies ARB staking through the DAO does not distribute protocol fee revenue to holders Substantial non-circulating ARB supply remains subject to scheduled token unlocks	Data uploads are immutable and cannot be deleted or modified Addresses are incompatible with standard Ethereum accounts despite shared secp256k1 curves Node operators face legal and GDPR compliance risks for hosted content Malicious packages targeted ecosystem npm developer libraries in June 2026
Best for	High-frequency DeFi traders, Rust and Solidity smart contract developers, Teams launching dedicated Orbit appchains	Permanent decentralized web hosting, Long-term data and AI archive preservation, Developers deploying autonomous on-chain agents
