Updating old paths (witnesses) for a balanced merkle forest accumulator

Introduction

It would be spiffy to use the balanced merkle forest idea for ethereum tokens or to store unspent transaction outputs.

Tadge Dryja has been working on 'utreexo' (presentation) for storing unspent transaction outputs in log(n) space; this gist is inspired by, and is very similar to, that work.

So my previous gist describes really simple algorithms for adding and removing items from a balanced merkle forest. This gist extends those operations to create

Bitcoin Transactions & Privacy (part 1)
This document is an attempt to define metrics quantifying the degree of privacy provided by a bitcoin transaction.
Objectives
Definition of metrics measuring the resistance of a transaction to a set of attacks against users privacy.
Attacks considered in the scope of these metrics are:
- Merged Inputs Heuristic: methods identifying the inputs controlled by a same entity
- Coinjoin Sudoku: methods identifying the links existing between the inputs and outputs of a transaction
