<pre> BIP: 49 Layer: Applications Title: Derivation scheme for P2WPKH-nested-in-P2SH based accounts Author: Daniel Weigl <DanielWeigl@gmx.at> Comments-Summary: No comments yet. Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0049 Status: Final Type: Informational Created: 2016-05-19 License: PD </pre> ==Abstract== This BIP defines the derivation scheme for HD wallets using the P2WPKH-nested-in-P2SH ([[bip-0141.mediawiki|BIP 141]]) serialization format for segregated witness transactions. ==Motivation== With the usage of P2WPKH-nested-in-P2SH ([[bip-0141.mediawiki#p2wpkh-nested-in-bip16-p2sh|BIP 141]]) transactions it is necessary to have a common derivation scheme. It allows the user to use different HD wallets with the same masterseed and/or a single account seamlessly. Thus the user needs to create dedicated segregated witness accounts, which ensures that only wallets compatible with this BIP will detect the accounts and handle them appropriat...

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. ...
