zkSync
ZK
zkSync is a Layer-2 scaling solution that preserves the security properties of the underlying blockchain by leveraging the latest generation of succinct zero-knowledge proofs. All funds in zkSync are held in a smart contract on the mainchain, while computation and storage are performed off-chain. For each Rollup block, a state transition zero-knowledge proof (SNARK) is generated and verified by the mainchain contract. This SNARK includes the proof of the validity of every transaction in the Rollup block.

zkSync is a cutting-edge Layer-2 scaling solution for Ethereum, leveraging zero-knowledge rollup (zk-rollup) technology to improve transaction speed and reduce gas costs while maintaining robust security. By bundling multiple transactions off-chain and only submitting minimal data to Ethereum, zkSync ensures faster and cheaper transactions without compromising Ethereum’s decentralized security guarantees.
One of zkSync’s standout features is its instant transaction finality using zk-SNARKs (succinct non-interactive arguments of knowledge), which allows users to experience immediate transfers and withdrawals, avoiding the delays seen in other rollup solutions like Optimistic Rollups. As of 2024, zkSync Era has become one of the leading Ethereum Layer-2 solutions, processing over 1.5 million daily transactions and consistently achieving high throughput with over 16 transactions per second (TPS). This performance solidifies zkSync as a frontrunner in Ethereum scalability.
zkSync offers full EVM compatibility, making it easier for developers to migrate their decentralized applications (dApps) to Layer-2 without significant changes. Additionally, zkSync’s Paymaster feature allows for flexible fee models, where users can pay transaction fees in tokens other than ETH, further enhancing the user experience.
With applications spanning DeFi, gaming, NFTs, and cross-chain infrastructure, zkSync is driving mass adoption by addressing Ethereum’s scalability challenges while maintaining a user-friendly environment. It represents a critical step towards a more efficient and accessible blockchain ecosystem.
