The traditional financial system has the ability to facilitate forensic investigations into crimes relating to financial fraud. The same cannot be said about the blockchain-based financial system that has come to exist over the past few years. This financial system does not tolerate third parties impeding transactions and so presents the problem of not being able to facilitate investigations. The concept of a blacklist is considered as a potential solution to this issue, specifically, a blockchain-centric blacklist. This paper describes the implementation and evaluation of such a blacklist as a potential solution for facilitating investigations involving blockchain-based financial systems.
