## Description

Join Guy Itzhaki, CEO of Fhenix, at Pragma San Francisco 2024 as he explores the transformative potential of Fully Homomorphic Encryption (FHE) in blockchain technology. Discover how FHE rollups and co-processors enhance blockchain privacy and scalability by enabling confidential smart contracts and encrypted computation.

Learn about the advantages of FHE compared to traditional privacy technologies like ZK proofs, MPC, and TEEs, and explore real-world applications including confidential 
transactions, sealed-bid auctions, decentralized identity, credit scoring, and confidential AI.
