Architecture

zkLink Nova is secured with zkLink Nexus, the multi-rollup settlement solution with Ethereum equivalent security.

In the zkLink Nexus mode, users could deposit fund to zkLink Nova from any connected network. All transactions need to be verified on a designated network (the primary chain) by zero-knowledge proofs. Additionally, the smart contract on Ethereum acts as the arbitrator to check if the transactions on different L2 rollups are consistent with the transactions on zkLink Nova network. This prevents malicious actions such as fraud deposit, and enables the entire system to inherit the security from the Ethereum Mainnet.
