Munstr (MuSig + Nostr) is a combination of Schnorr signature based MuSig (multisignature) keys in a terminal based wallet using decentralized Nostr networks as a communication layer to facilitate a secure and encrypted method of transporting and digitally signing bitcoin transactions in a way that chain analysis cannot identify the nature and setup of the transaction data.

To anyone observing the blockchain, Munstr transactions look like single key Pay-to-Taproot (P2TR) spends.
