ZK-Rollups

A way to make blockchain faster and cheaper. It bundles many transactions together and processes them off the main network, then proves they're valid.

Example

Using zkSync to send money for less than $0.10 instead of paying $10+ on regular Ethereum.

  1. 1

    Collect Transactions

    Users submit transactions to the L2 network

  2. 2

    Bundle Together

    Hundreds of transactions are batched into one

  3. 3

    Generate Proof

    Complex math creates a cryptographic proof of validity

  4. 4
