BitSniffer: A tool for linkability analysis

Team Members: Ryan Anderson, Luke Gessler, and Sam Prestwood

This is the code repository for our final project for CS 4501: Crypto Currency Cabal.

Overview:

BitSniffer is a tool for quantifying the linkability of Bitcoin addresses. The tool can perform two types of operations:

  1. When one address sends BTC to a second address via a mixing service, the tool searches the blockchain for a transaction path between the addresses and calculates the size of the anonymity set for the output address.

  2. For two arbitrary addresses, the tool calculates a set of metrics for estimating the linkability between the two addresses.

Dependencies:

How to run:

Clone this repository, then, in the root code directory, run:

python3 webapp.py

This will launch a web interface that can be accessed in your browser at http://localhost:8080
