Privacy by Design, How Midnight Changes Smart Contracts

Most smart contracts today are transparent by default. Every input and output is visible, which creates serious privacy risks when contracts handle real-world data.
Midnight flips this model.
On Midnight, developers can program visibility directly into smart contracts. They decide what information is public, what is private, and what can be selectively revealed.
Instead of exposing raw data, contracts produce proofs. These proofs confirm that rules were followed — without leaking unnecessary details.
This design is especially important for applications like:
Identity verification
Compliance systems
Private payments
Voting and governance
Midnight doesn’t remove trust by hiding information — it removes trust by verifying facts cryptographically. That’s a much more sustainable model for long-term use.
