Overview

zkLink modular stack provides unparalleled scalability for dApps building on top of our ecosystem. Each module of zkLink Nova can be upgraded independently, allowing us to have the capability to deliver the best performance by flexibly combining the best technologies.

The network can be decomposed into four layers:

• Sequencing Layer: Collect and order transactions.

• Execution Layer: Process transactions and update states.

• Settlement Layer: Finalize transactions on the base chains and execute fund withdrawal.

• Data availability(DA) Layer: Ensure data is available.

It is worth to note that our innovative multi-chain settlement scheme makes us the first aggregated Layer 3 rollup network connecting to Ethereum and multiple Layer 2 rollup networks (L2s) with Ethereum equivalent security.
