Starknet Alpha launches on Ethereum mainnet
StarkWare put Starknet Alpha on Ethereum mainnet: a rollup that runs general smart contracts off-chain and posts cryptographic STARK proofs to Ethereum so they inherit its security. It launched with a single sequencer, a whitelist for apps, no audit yet and no fees; StarkWare's earlier systems had settled over 50M transactions and $250B.
- Type: permissionless decentralized rollup L2; posts state diffs on-chain.
- Proof system: STARK (Scalable Transparent ARgument of Knowledge), not SNARKs.
- Launch status: Alpha, single sequencer, app whitelist, unaudited, no fees charged.
- StarkWare track record: earlier systems (StarkEx) settled 50M+ transactions and $250B since Summer 2020.
