Back Up a Multisig Wallet with BSMS
Note [BIP-129 BSMS (Bitcoin Secure Multisig Setup) compliant]
Coconut implements BSMS, a standard that defines how multisig wallet configurations are exchanged.
Multisig setup formats used to differ between wallet apps, which could make a wallet created in one app unusable in another. BSMS provides a common setup procedure to solve this interoperability problem. Coconut's multisig features follow this standard.
