## Overview

Cardano's privacy answer is Midnight, a separate partner chain that reached federated mainnet in March 2026 with a dual ledger, ZK proofs and selective disclosure. It is not Cardano mainnet, and it is not yet permissionless: nodes are operated by a named federation while decentralization is phased in. Attention and adoption have been quiet since launch.
