zkSync is a Layer-2 scaling solution for Ethereum, designed to enhance the network's scalability and efficiency by utilizing zero-knowledge rollups (ZK-rollups). ZK-rollups bundle multiple transactions together off-chain and then submit a single, cryptographically verified proof back to the Ethereum mainnet. This reduces transaction fees, increases throughput, and maintains Ethereum's core security principles https://app.orioleinsights.io/projects/zksync

Key Features of zkSync:

1. Zero-Knowledge Proofs: zkSync uses cutting-edge zero-knowledge technology to validate transactions without revealing sensitive data, ensuring privacy and security.
2. Low Transaction Fees: By processing transactions off-chain, zkSync significantly reduces gas fees, making Ethereum more accessible for microtransactions.
3. Fast Transactions: zkSync enables nearly instant transaction finality, as users don’t need to wait for Ethereum block confirmations.
4. Ethereum Security: All zkSync transactions are ultimately validated by the Ethereum mainnet, ensuring the same level of security as Layer 1.

zkSync is expected to play a crucial role in Ethereum’s scalability, especially as decentralized applications (dApps) and DeFi platforms grow in popularity.
