" summary

Offchain Labs describes Arbitrum 2.0 as a rollup that moves computation and storage off-chain while keeping Ethereum-level security, with ArbOS executing contracts and verifying batches at layer two. Beta1 delivers about 10x cost and ~400 TPS for Reddit-like workloads; beta2 claims full EVM compatibility with zero code changes, up to 4,000 TPS and ~100x total cost reduction, trustless finality tied to Ethereum, mainnet planned Q4 2020 and sidechains (40,000 TPS, 1000x goal) projected Q1 2021.
