What is Midnight?

Midnight is a data protection blockchain platform. It addresses a fundamental challenge in blockchain technology: how to use the benefits of distributed ledgers while maintaining the privacy required for sensitive data.

Unlike traditional blockchains where every transaction is permanently visible to all participants, Midnight introduces selective disclosure — the ability to prove facts about data without revealing the data itself. This enables blockchain adoption in regulated industries like healthcare, finance, and government services where data protection is not just important, but legally required.

Core concepts

Data protection blockchain

Midnight maintains two parallel states:

• Public state: Traditional blockchain data stored on-chain, visible to all network participants. This includes transaction proofs, contract code, and any intentionally public information.
• Private state: Encrypted data stored locally by users, never exposed to the network. This includes personal information, business data, and any sensitive content that must remain confidential.
