Zero-Knowledge Proofs applied to finance

A Zero Knowledge Proof (ZKP) is a cryptographic tool that allows a party to prove knowledge of a secret to another party without revealing said secret. ZKPs have been around since the mid-80s. But with the dawn of Distributed Ledger Technology (DLT) the development of new zero-knowledge proof protocols has opened the door for new possible applications. Applying ZKPs to cases in finance where there is a trade-off between confidentiality and transparency could provide a way to add more transparency in these activities without compromising the confidentiality.
