Midnight & Partner Chains
Discover Cardano's Partner Chains framework and Midnight, a data-protection and compliance-ready sidechain.
The Partner Chains Framework
Cardano is designed to be a highly secure and decentralized global settlement layer. However, different applications (like enterprise networks, gaming, or privacy ledgers) have distinct requirements. To support this diversity, IOG developed the Partner Chains Framework. This modular architecture allows independent blockchains to launch using their own rules while borrowing Cardano's robust security, liquidity, and decentralized node network.
What is Midnight?
Midnight is the pioneer blockchain built using the Partner Chains framework. It is a data-protection sidechain designed to resolve a fundamental blockchain paradox: how to maintain user privacy while complying with global financial regulations.
Core Technologies and Features
- Programmable Data Protection: Midnight utilizes advanced Zero-Knowledge Proofs (ZKPs). This allows developers to write smart contracts that prove facts (e.g., "This user is over 18 years old" or "This account has sufficient funds") without disclosing the private personal data on the public ledger.
- Dual-Ledger Architecture: Midnight splits its ledger into public and private spaces. The public side handles coordination and consensus, while the private side hosts confidential logic, protecting IP, commercial secrets, and personal identity.
- Compliance by Design: Unlike completely anonymous "privacy coins" which are often banned by regulators, Midnight allows users to selectively disclose information to auditors or regulators, ensuring regulatory compliance.
The Dual-Token Economy
Midnight is powered by a unique dual-token system:
- NIGHT: The native governance and staking token. It has a fixed supply and is used to secure the network.
- DUST: A non-speculative, utility resource used to pay for transaction fees. DUST is continuously generated by holding NIGHT, isolating fee costs from asset price volatility.
Shared Security with Cardano
Through the Partner Chains framework, Cardano Stake Pool Operators (SPOs) can opt-in to secure the Midnight network in parallel. By running Midnight nodes, SPOs earn additional block rewards, strengthening both ecosystems and bootstrapping Midnight's security immediately.
