## Privacy Preserving Finance

Privacy preserving finance, or PriFi, focuses on developing financial systems that offer the benefits of decentralization while protecting user transaction data. In traditional finance, privacy is maintained by banks and intermediaries, but in crypto, everything is typically public.

PriFi aims to bridge this gap by using technologies like Zero-Knowledge proofs and homomorphic encryption to allow for private, compliant, and efficient financial interactions. This is particularly important for institutional players who do not want their trading strategies exposed to the public market.

By ensuring confidentiality, PriFi encourages more participation from entities that prioritize privacy for competitive or regulatory reasons. It is a critical frontier for the next phase of decentralized finance development.
