The article discusses the release of an open source wallet called Munstr, which combines Schnorr signature-based MuSig keys and decentralized Nostr networks to enable a group of signers to coordinate an interactive signing session for taproot-based outputs. This makes it possible to transport and digitally sign bitcoin transactions in a way that chain analysis cannot identify the nature and setup of the transaction data, and to make Munstr transactions look like single key Pay-to-Taproot spends for anyone observing the blockchain. However, the article notes that this software is in beta and should not be used for real funds. The GitHub repository is also provided for those who want to learn more about the wallet.

autonote from dev: the input text for this summary had to be modified for ChatGPT to summarize it.

This is pretty cool (schnorr key aggregation is black magic), but what applications do you think could benefit from relaying over Nostr? If you know the person you're joining a multisig with, couldn't you do the communication over any encrypted channel?

Could this be used for some sort of mixing service? For example all users in a pool deposit into an n-of-n multisig and at some point in the future start withdrawing (not sure if this would yield privacy benefits)
