67 - Deterministic Pay-to-script-hash multi-signature addresses through public key sorting

<pre> BIP: 67 Layer: Applications Title: Deterministic Pay-to-script-hash multi-signature addresses through public key sorting Author: Thomas Kerin <me@thomaskerin.io> Jean-Pierre Rupp <root@haskoin.com> Ruben de Vries <ruben@rubensayshi.com> Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0067 Status: Proposed Type: Standards Track Created: 2015-02-08 License: PD </pre> ==Abstract== This BIP describes a method to deterministically generate multi-signature pay-to-script-hash transaction scripts. It focuses on defining how the public keys must be encoded and sorted so that the redeem script and corresponding P2SH address are always the same for a given set of keys and number of required signatures. ==Motivation== Pay-to-script-hash (BIP-0011<ref>[https://github.com/bitcoin/bips/blob/master/bip-0011.mediawiki BIP-0011]</ref>) is a transaction type that allows funding of arbitrary scripts, wher...

<pre> BIP: 123 Title: BIP Classification Author: Eric Lombrozo <elombrozo@gmail.com> Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0123 Status: Active Type: Process Created: 2015-08-26 License: CC0-1.0 GNU-All-Permissive </pre> ==Abstract== This document describes a classification scheme for BIPs. BIPs are classified by system layers with lower numbered layers involving more intricate interoperability requirements. The specification defines the layers and sets forth specific criteria for deciding to which layer a particular standards BIP belongs. ==Copyright== This BIP is dual-licensed under the Creative Commons CC0 1.0 Universal and GNU All-Permissive licenses. ==Motivation== Bitcoin is a system involving a number of different standards. Some standards are absolute requirements for interoperability while others can be considered optional, giving implementors a choice of whether to support them. ...
