w2ui is a really nice frontend library for creating grids, forms, and all sorts of simple but high quality html frontend interfaces.

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

Using debuggers with Bitcoin Core

Please also refer to Fabian Jahr's excellent documentation and video. In this document, I'll cover only some of what his document does in slightly greater detail, while trying not to duplicate too much, and focused on gdb and Linux.

Video version of (most of) this document: https://vimeo.com/576956296/df0b66fbfc NOTE if you watch the video: Near the end, I had problems attaching to
