Settlement Layer

A classic ZK-Rollup network typically selects a single chain, i.e, Ethereum as the settlement layer to verify the proofs and settles the transactions. The settlement layer maintains the security and integrity of off-chain transactions.

In order to securely aggregate liquidity and native assets across L1s and L2s, zkLink introduces two new paradigms of settlement layer deployment solutions to its rollup infra framework - zkLink Nexus and zkLink Origin.

Nexus: Settlement on ETH ZK-L2s

Origin: Settlement on ETH and Alt-L1s
