# Mina Schnorr signatures on Pallas

Key-prefixed Schnorr signatures over Pallas, one of the two Pasta curves, adapted from BIP 340 and used to authorise Mina transactions and account updates. Broken by Shor's algorithm on a cryptographically relevant quantum computer, which recovers the private key from the public key.

- **Quantum status:** Broken by Shor's algorithm on a cryptographically relevant quantum computer.
- **Standard:** No published standard.
- **Family:** elliptic curve.
- **Also known as:** Mina Schnorr, Schnorr-Pallas.

## Rated chains using it

- [Mina Protocol](https://hardyindex.com/chains/mina.md): account signatures, mainnet, default. Key-prefixed Schnorr signatures over the Pallas curve, adapted from BIP 340, authorise every Mina transaction and account update.
