Reusable taproot addresses

Abstract

This document proposes a new scheme to avoid address reuse while retaining some of the convenience of address reuse, keeping recoverability purely from Bitcoin time chain and avoiding visible fingerprint. The scheme has negligible average overhead.

Motivation

The `bitcoin-core/guix.sigs` Repository Workflow

Common environment variables

export SIGNER="hebasto"
export GUIX_SIGS_REPO="/home/hebasto/guix.sigs"
export DETACHED_SIGS_REPO="/home/hebasto/bitcoin-detached-sigs"

Debugging Bitcoin Core

This guide is designed to give beginners of C++ development and/or people new to the bitcoin core code base an overview of the tools available for debugging issues as well as giving hints where issues may trip you up.

Network partition resistance

For the Bitcoin network to remain in consensus, the network of nodes must not be partitioned. So for an individual node to remain in consensus with the network, it must have at least one connection to that network of peers that share its consensus rules. This document describes how we attempt to achieve this.

We can't rely on inbound peers to be honest, because they are initiated by others. It's impossible for us to know, for example, whether all our inbound peers are controlled by the same adversary.

Navigating while typing

Let’s start by what you can do while typing. These keystrokes change only what happens on the input line (the line where you type stuff).

arrow left/right: move one character left or right.

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."
