Which Chain is ZKsync (ZK) On?

Overview

ZKsync is a Layer 2 scaling solution for Ethereum that utilizes zero-knowledge (ZK) proofs to achieve high transaction throughput and low fees. It operates on top of the Ethereum mainnet, inheriting its security and decentralization while enhancing scalability.

Chain Compatibility

ZKsync is compatible with the Ethereum Virtual Machine (EVM), meaning developers can seamlessly deploy and execute Ethereum-based smart contracts and decentralized applications (dApps) on the ZKsync network.

Network Structure

ZKsync consists of two main components:

• Ethereum Mainnet: The underlying blockchain on which ZKsync settlement and finality occur.
• Rollup Layer: A separate layer where transactions are batched together, processed off-chain, and submitted to the mainnet in compressed form as ZK proofs.

Technical Implementation

ZKsync employs a ZK-rollup architecture, which involves:

• Transaction Batching: Transactions are grouped into batches before being processed.
• ZK Proof Generation: ZK proofs are cryptographic attestations that validate the correctness of the batch without revealing individual transaction details.
• Proof Submission: ZK proofs are submitted to the Ethereum mainnet for verification and final settlement.

Benefits of ZKsync

ZKsync offers several advantages over the Ethereum mainnet:

• Increased Transaction Throughput: ZK-rollups significantly increase transaction throughput by processing transactions off-chain.
• Substantially Reduced Fees: Offloading transaction processing to the rollup layer reduces gas fees incurred on the mainnet.
• Enhanced Privacy: ZK proofs protect the privacy of individual transactions, making them unsuitable for public scrutiny.
• EVM Compatibility: Developers can leverage existing Ethereum tools and expertise to develop dApps on ZKsync.

ZKsync and Ethereum

While ZKsync operates as a Layer 2 solution on top of Ethereum, it maintains a symbiotic relationship with the mainnet:

• Security: ZKsync inherits the security of Ethereum by settling transactions on the mainnet.
• Finality: Transactions finalized on the mainnet are considered immutable and irreversible.
• Interoperability: ZKsync allows users to seamlessly transfer assets between Ethereum and the rollup layer.
