Proof of Innocence allows users to demonstrate anonymously that their funds did not originate from a blacklisted set of transactions.
By leveraging zero-knowledge cryptography, users can construct statements about private information that can be verified by third parties. In this case, we want to prove that users' funds are not part of a specified set of unlawful transactions, without revealing the specific transaction in which the user was involved. In an increasingly scrutinized and compliant financial landscape, such a mechanism will facilitate safer participation for users who wish to uphold their privacy rights.
This technical report shows the research done before implementing a Proof of Innocence (PoI) protocol in Cardano. It first describes the problem of PoI along with some use cases. Secondly, it shows existent implementations in other blockchains. Finally, it proposes a solution in Cardano and describes the technical challenges that need to be addressed.
