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	Throughput rated at 10,000 transactions per second on Cosmos Database queries are free of transaction gas charges Storage allows mutable updates rather than paying for permanent bloat IBC integration connects liquidity to Osmosis and the wider Cosmos network
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	Expired storage leases purge data automatically unless renewed Pivoted focus across general data, GameFi, and DeSci over time Requires bridging between ERC-20 and native Cosmos Layer 1 BLZ tokens
Best for	High-frequency DeFi traders, Rust and Solidity smart contract developers, Teams launching dedicated Orbit appchains	DeSci developers storing mutable scientific data, Builders requiring high-throughput Cosmos appchains, Applications needing no-fee database queries
