Transaction privacyZero-knowledge proofs
Transaction visibilityAll participants have access to all entries ever recorded.
Transaction orderingTransactions are filled into batches and committed to the chain. Proof is generated for each batch, and then submitted for verification by the smart contract.

Fault tolerance

Tied to the finality and security of the underlying L1 Ethereum chain. There is a delay of ~21 hours for L1 finality as a security measure during alpha.


Depends on the Ethereum mainchain for publishing and verification. Transactions on the L2 chain are processed right away and added to blocks, which are generated immediately. Once fully decentralized, block time will take a couple of seconds.

Industry use case

Secure, scalable, and cost-efficient large-scale DeFi, NFT, and GameFi DApps.
