39 - Mnemonic code for generating deterministic keys

BIP: 39 source Layer: Applications Title: Mnemonic code for generating deterministic keys Author: Marek Palatinus Pavol Rusnak Aaron Voisine Sean Bowe Comments-Summary: Unanimously Discourage for implementation Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0039 Status: Proposed Type: Standards Track Created: 2013-09-10 Table of ContentsAbstractMotivationGenerating the mnemonicWordlistFrom mnemonic to seedWordlistsTest vectorsReference ImplementationOther Implementations Abstract This BIP describes the implementation of a mnemonic code or mnemonic sentence -- a group of easy to remember words -- for the generation of deterministic wallets. It consists of two parts: generating the mnemonic and converting it into a binary seed. This seed can be later used to generate deterministic wallets using BIP-0032 or similar methods. Motivation A mnemonic code or sentence is superior for human interaction compared to the handling o...

123 - BIP Classification

BIP: 123 source Title: BIP Classification Author: Eric Lombrozo 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 Table of ContentsAbstractCopyrightMotivationSpecification1. Consensus LayerSoft ForksHard Forks2. Peer Services Layer3. API/RPC Layer4. Applications LayerClassification of existing BIPs 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.
