Its comprehensive privacy advantages are anchored in three architectural pillars:
Dual-State Architecture
Midnight separates the network into two distinct layers to balance auditability with confidentiality:
Public State: A traditional ledger for consensus, governance, and final settlement that is visible to all participants.
Private State: Encrypted data that is stored locally on the user's device and never touches the public blockchain.Selective Disclosure via Zero-Knowledge Proofs (ZKPs)
Utilizing recursive zk-SNARKs, Midnight allows users to prove the validity of a statement without revealing the underlying sensitive information.
Actionable Example: A user can prove they are over 18 years old or possess sufficient funds for a loan without revealing their actual birthdate or bank balance.
Privacy by Default: Sensitive metadata—such as sender/receiver identities and transaction amounts—remains shielded.Compliance-First "Rational Privacy"
Unlike earlier "privacy coins" that often clashed with regulations, Midnight is built to satisfy global standards like GDPR and HIPAA.
Programmable Privacy: Developers use a TypeScript-based language called Compact to write smart contracts that define exactly who can see what and under what conditions.
Auditability: Users can provide cryptographic proofs of correctness to regulators or auditors without exposing raw, proprietary databases.
