FHE crossed the chasm—let’s move real data, not just toy integers
Last year fully homomorphic encryption (FHE) felt like a moon-shot; this year it’s a power tool. ISO has a draft standard on the street, Zama’s Rust stack screams on GPUs, and bootstraps run an order of magnitude faster than they did in 2023. That’s enough lift for production pilots in banking, healthcare, and AdTech. Lucenor’s take: when the math finally bends to operational reality, you ship—secure-by-design, zero-trust baked in. Below is the state-of-play and a hands-on demo that manipulates encrypted ASCII strings instead of the usual “8 + 5” cliche. But first..
Beyond Blockchains: Zero-Knowledge Proofs for Everyday IT
Web3 may have made zero-knowledge proofs headline-worthy, but the math was never chained to blockchains. In 2025, regulatory pressure for privacy-by-design, relentless credential breaches, and the march toward zero-trust all push mainstream IT to adopt ZKP as a native control—long before most enterprises even mint a token. This post walks through the cryptographic intuition (with approachable numbers), showcases five Web2-centric use-cases that are shipping today, and explains how Lucenor’s applied-cryptography engineers translate elegant theory into hardened systems.
