Zircuit’s trailblazing L2 research has led to the development of an EVM-compatible ZK-rollup that allows faster transactions, lower fees, and higher security.

In this quick guide, you’ll learn about Zircuit’s core features, transaction flow, and key differentiators, including circuit decomposition and security at the sequencer level.

Before diving into the specifics of Zircuit, here’s a short refresher on ZK-rollups and their pros and cons.

Quick Overview: What Are ZK-Rollups?

Zero-knowledge rollups, or ZK-rollups, are L2 scaling solutions designed to increase Ethereum’s transaction throughput by moving computation and state-storage off-chain.

They’re called “rollups” because they roll up (i.e., bundle) a set of transactions, process them off-chain, and only submit a summary representing all the batched transactions to the mainnet.

In addition to this summary, ZK-rollup nodes submit a validity proof confirming the veracity of the off-chain transactions. The validity proof is verified by a smart contract deployed on the L1 chain.
