BIP: 379 source Layer: Applications Title: Miniscript Author: Pieter Wuille Andrew Poelstra Sanket Kanjalkar Antoine Poinsot Ava Chow Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0379 Status: Draft Type: Informational Created: 2023-10-10 License: CC0-1.0 Abstract This document specifies Miniscript, a language for writing (a subset of) Bitcoin Scripts in a structured way, enabling analysis, composition, generic signing and more. Copyright This document is licensed under the Creative Commons CC0 1.0 Universal license. Motivation Bitcoin Script is an unusual stack-based language with many edge cases, designed for implementing spending conditions consisting of various combinations of signatures, hash locks, and time locks. Yet, despite being limited in functionality, it is still highly nontrivial to: Given a combination of spending conditions, finding the most economical scrip...
328 - Derivation Scheme for MuSig2 Aggregate Keys
BIP: 328 source Layer: Applications Title: Derivation Scheme for MuSig2 Aggregate Keys Author: Ava Chow Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0328 Status: Proposed Type: Informational Created: 2024-06-04 License: CC0-1.0 Table of ContentsAbstractCopyrightMotivationSpecificationTest VectorsBackwards CompatibilityRationaleReference ImplementationAcknowledgements Abstract This document specifies how BIP 32 extended public keys can be constructed from a BIP 327 MuSig2 aggregate public key and how such keys should be used for key derivation. Copyright This BIP is licensed under the Creative Commons CC0 1.0 Universal license. Motivation Multiple signers can create a single aggregate public key with MuSig2 that is indistinguishable from a random public key. The cosigners need a method for generating additional aggregate pubkeys to follow the best practice of using a new address for every payment. The obvious met...
