How it works

The architecture behind simple-looking vouchers.

mintus glues three things together so businesses don't have to: a fast public chain for settlement, programmable smart contracts for voucher logic, and a DID layer for friction-free consumer identity.

1. A high-performance public chain

mintus is built on a public chain optimized for high-throughput, low-value commercial transactions. Block finality is measured in hundreds of milliseconds, and per-transaction fees are denominated in fractions of a cent — making it economical to settle even a coffee-shop punch on-chain.

The chain is public, which matters: anyone can independently verify a voucher exists, who owns it, and whether it has been redeemed. Neither mintus nor a merchant can rewrite that history.

2. Programmable voucher contracts

Every voucher you issue with mintus is an instance of an audited smart-contract template. When you configure a campaign in the Enterprise Console, the platform compiles your settings — supply, expiry, redemption locations, transferability, blacklist, redemption ceilings — into deterministic on-chain rules.

The contracts are open and auditable. A consumer wallet can inspect a voucher's rules before accepting it; a regulator can verify them after the fact.

3. Decentralized identity (DID) for consumers

Asking a coffee-shop customer to memorize a 24-word seed phrase is not a viable path to mainstream adoption. mintus solves this by giving every consumer a DID — a portable on-chain identity — bound to a familiar username and password.

Behind the scenes, the consumer's signing keys are protected by a combination of device-bound enclaves and threshold cryptography. If a user loses their device, they can recover their DID through email plus security questions. The user holds their assets; the user does not have to hold a paper backup.

4. Real-time settlement & reconciliation

When a cashier scans a customer's voucher, the Cashier App constructs a redemption transaction, the consumer's wallet signs it (via the DID), and the chain finalizes it in under a second. The voucher is burned, the merchant's liability decreases, and both parties' wallets reflect the new state immediately.

Because every action is on-chain, end-of-day reconciliation collapses from a multi-step accounting task into a one-click report.
