Layer 2 vs Zero-Knowledge Proof

Layer 2 refers to secondary protocols and networks built on top of a blockchain's base layer (Layer 1) that process transactions off-chain while inheriting the security of the underlying blockchain, enabling higher throughput, lower fees, and faster confirmations without changing the base protocol.

A cryptographic method that allows one party (the prover) to demonstrate to another party (the verifier) that a statement is true without revealing any information beyond the fact that the statement is true.
