FHE is structurally quantum resistant, schemes are based on lattice-based problems. These hardness assumptions are similar to those that underpin the post-quantum standards established by NIST. - This is critical for the infrastructure being built today data and computational states encrypted using classical schemes could be harvested now and decrypted later. Once cryptographically relevant quantum computers emerge. - On public blockchains, as well as in cloud or DeFi systems with long lifespans, this risk is permanent historical records cannot be retroactively secured through a future upgrade. - Meanwhile, the underlying encryption remains post-quantum secure, regardless of when large-scale quantum hardware arrives. - For any system designed to protect privacy whether through confidential smart contracts, private transaction logic, or encrypted AI inference adopting FHE today effectively removes the quantum clock from the system @fhenix
