A response to @nothingmuch

This is an unathorized and not solicited response to the short, but rather strong, tweets from @nothingmuch about the very-soon-comming Wasabi Wallet 2.0 release.

I feel the need to write here because @nothingmuch is the father of WabiSabi, the cryptographic protocol that makes Wasabi Wallet 2.0 new unequal-value outputs transactions possible, as well as the mind behind some critical components needed by the coinjoin implementation, and because, even though it could result in redundant to say, he's talented and a real expert in the field. Also, and this is the most important reason, i think, it's that even when it is evident he is not on good terms with the team, he is being honest in his concerns and then i cannot simply ignore what he says.

First, in my opinion tweets are good for saying what you want to say but are not very good for explaining

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.

First and foremost the manual mentions it explicitly:

[Use] the standalone home-manager tool. For platforms other than NixOS (...), this is the only available choice. (...) See Section 1.1, “Standalone installation” for instructions (...)

The purpose of this document is keep track of my learning process while I learn F#.

Introduction

My first programming language was Basic, Sinclair BASIC first and GW-BASIC a few months later, then DBase III+, then Clipper Summer 87, then Clipper 5, Pascal 4.5, FoxPro, Microsoft Macro Assembler, C, C++, Delphi, Builder C++, Visual Basic, and many more until C#.

Nowadays there are thousands and thousands of programming languages but only a few concentrate the huge majority of programmers. However, something is clear: programming languages don't last forever or are not cool forever. Whoever

Architecture

• Use Onion architecture

  • Dependencies go inwards. That is, the Core domain doesn't know about outside layers

• Use pipeline model to implement workflows/use-cases/stories

  • Business logic makes decisions
  • IO does storage with minimal logic
  • Keep Business logic and IO separate

• Keep IO at edges

Useful tips and tricks

lontivero

1) COPY SSH KEYS TO USER@HOST TO ENABLE PASSWORD-LESS SSH LOGINS. (NOT ON MAC)

ssh-copy-id user@host

To generate the keys use the command ssh-keygen

2) START A TUNNEL FROM SOME MACHINE’S PORT 80 TO YOUR LOCAL POST 2001

ssh -N -L2001:localhost:80 somemachine
