zkSync Era (ZK)

What is the zkSync Era blockchain?​

zkSync Era is a Layer 2 scaling solution for Ethereum that uses zero-knowledge rollups to provide faster and cheaper transactions without compromising on security.

Here are 5 key points about zkSync Era:

Zero-knowledge rollups: Transactions are bundled and submitted to Ethereum with cryptographic proofs, ensuring efficiency and security.

EVM compatibility: Fully compatible with Ethereum Virtual Machine (EVM), allowing existing Ethereum dApps to deploy with little to no changes.

Advanced features: Includes account abstraction and paymasters, enabling flexible transactions and ERC20 fee payments.

High throughput: Capable of handling thousands of transactions per second, significantly improving speed compared to Ethereum Layer 1.

Cross-chain interoperability: Supports a network of interconnected ZK chains, improving communication and scalability across ecosystems.
