Blind minting underpins fungibility and privacy in digital cash. It lets users spend tokens without the issuer or observers tracing the payment history. While historically theoretical, modern implementations (e.g., Cashu, privacy layer-2s)

1. What Is a Blind Mint
A blind mint is a privacy technique where a user obtains a signed token or coin without revealing to the signer which specific commitment is being signed. It is the cryptographic foundation of private digital cash systems.
2. How It Works
In a blind-signature scheme, the user blinds a commitment before sending it to the issuer. The issuer signs the blinded value without seeing the underlying message; the user then unblinds the signature to obtain a valid token redeemable later. This prevents the issuer from linking the issuance to the redemption, providing unlinkability. Systems like eCash and privacy-focused chains use variants of this technique.
3. Why It Matters
Blind minting underpins fungibility and privacy in digital cash. It lets users spend tokens without the issuer or observers tracing the payment history. While historically theoretical, modern implementations (e.g., Cashu, privacy layer-2s) bring blind-mint-based ecash to live systems.
4. Key Facts
- Concept originated with David Chaum's blind signatures (1982)
- Cashu is a Chaumian ecash implementation for Bitcoin
- Provides unlinkability between mint and spend
- Nutshell implementations exist across multiple mints
