Overview
Midnight is a blockchain platform that lets developers build apps which keep people's data private while still proving their transactions are valid. It suits businesses that handle confidential information and need to protect it on a public network. Its key idea is selective disclosure: an app can prove a fact, like someone being over 18, without revealing the data behind it.
Midnight is a partner chain of Cardano, an established public blockchain. A partner chain is a separate network that runs on its own but stays closely linked to a larger one, sharing security and letting assets move between them. Midnight runs a live mainnet with its own ledger and consensus, and its NIGHT token trades on major centralized exchanges1. To keep data private, it relies on zero-knowledge proofs, a method of confirming something is true without exposing the information that proves it, so the network stays open and checkable while sensitive details remain hidden2.
Key Features
- Private data that stays verifiable. Apps keep personal or business information hidden while still proving to the public network that they followed the rules, using zero-knowledge proofs2.
- Selective disclosure. Someone can reveal exactly what a situation calls for (proof of age, proof of funds) and nothing more, which fits regulations and audits without over-sharing2.
- Familiar tools for developers. Midnight's own smart contract language, Compact, is designed to feel like TypeScript, so developers can add privacy features without deep cryptography expertise3.
- Fees paid by a self-renewing resource. Holding the NIGHT token automatically produces DUST, a separate resource that covers transaction costs and refills over time, so people are not spending their main asset on every action4.
- Shared security with Cardano. Cardano stake pool operators can help run and secure Midnight, which links the two networks and lets assets move between them5.
What to Expect
For token holders, the entry point is NIGHT: a Cardano native asset that lives on the Cardano network and can be held in a Cardano-compatible wallet such as Lace. NIGHT was initially distributed to eligible ADA holders through an event called the Glacier Drop, and it trades on several major exchanges. Simply holding NIGHT produces DUST over time, the resource that covers fees when you interact with Midnight apps.
For developers, getting started is designed to be approachable. The Midnight Developer Academy explains the core ideas (how the network agrees on transactions, the cryptography behind private data, and the NIGHT and DUST model) before you move on to the full technical documentation. Building an app means writing it in Compact, with open-source examples available through the project's GitHub organization. A community forum, an active Discord server, regular hackathons, and a technical fellowship give builders places to ask questions and learn.
