178 - Version Extended WIF
BIP: 178 source Layer: Applications Title: Version Extended WIF Author: Karl-Johan Alm Comments-Summary: Discouraged for implementation (one person) Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0178 Status: Draft Type: Standards Track Created: 2018-04-04 License: CC0-1.0 Table of ContentsAbstractMotivationSpecificationCompatibilityAcknowledgementsReference implementationReferencesCopyright Abstract An extension to the Wallet Import Format (WIF) to specify what kind of bitcoin address the private key corresponds to. Motivation There are several types of bitcoin addresses which can all be associated with a given private key: P2PKH (legacy 1... format), P2SH-P2WPKH (SegWit public key inside P2SH), P2WPKH (bech32), etc. While private keys have a 1-byte suffix indicating whether the corresponding public key is compressed (0x01) or not (through suffix absence), there is no way of knowing what kind of bitcoin address were associated with the private key....

Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0325 Status: Proposed Type: Standards Track Created: 2019-03-20 License: CC0-1.0 Table of ContentsAbstractMotivationSpecificationGenesis Block and Message StartGenesis BlockMessage StartCompatibilityReference implementationReferencesCopyright Abstract A new type of test network where signatures are used in addition to proof of work for block progress, enabling much better coordination and robustness (be reliably unreliable), for persistent, longer-term testing scenarios involving multiple independent parties. Motivation Testnet is a great place to try out new things without risking real money, but it is notoriously unreliable. Huge block reorgs, long gaps in between blocks being mined or sudden bursts of blocks in rapid succession mean that realistic testing of software, ...

Motivation The current message signing standard only works for P2PKH (1...) invoice addresses. We propose to extend and generalize the standard by using a Bitcoin Script based approach. This ensures tha...
