FHE is quantum-resistant by nature not by retrofit. Practical schemes are built on lattice problems (LWE and variants). These resist the quantum algorithms that break today’s elliptic-curve and RSA systems. The security is structural, not an add-on. That matters for infrastructure being built now. Sensitive data and private computation layers written today will still exist when quantum computers mature. Systems that rely on classical crypto will need to be replaced; lattice-based FHE won’t. @fhenix is building this foundation for Ethereum confidential computation that stays encrypted through execution and is post-quantum from day one.
