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.

module Effect =

    /// Create value with no dependency requirements.
    let inline value (x: 'out): Effect<'env,'out> = Effect (fun _ -> async.Return x)
    /// Create value which uses depenendency.

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

Prerequisites

We'll use NixOps to deploy, so we need to install it

nix-env -i nixops

And to deploy on DigitalOcean we need to have an account and create an API access token for it.

Making Toys with F# - A Small Elm-like DSL in F#

I've been working on a talk about the virtues of building toy examples for the purpose of communicating ideas with simple interactive examples.

The toys I talk about in my presentation are based my interest in tools that allow programmers to quickly build web applications that allow them to explore their architecture. So to kickstart this series off, I want to introduce a simple
