Discover key facts and figures about major blockchain protocols that are empowering transformations across industries.
zkSync Era is a user-focused, EVM-compatible protocol secured by zero-knowledge proofs, offering scalable and cost-efficient solutions for large-scale applications.
| Consensus | Proof-of-stake (PoS) with zkSync Era |
| Public / Private / Permissioned | Public |
| Smart contracts | Yes |
| Smart contract language(s) supported | Solidity, Vyper, Yul, Huff |
| Transaction privacy | Zero-knowledge proofs |
| Transaction visibility | All participants have access to all entries ever recorded. |
| Transaction ordering | Transactions are filled into batches and committed to the chain. Proof is generated for each batch, and then submitted for verification by the smart contract. |
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.
Secure, scalable, and cost-efficient large-scale DeFi, NFT, and GameFi DApps.
