Hi friends!
Today let’s break down what Fully Homomorphic Encryption (FHE) is and how @zama uses this technology to make blockchains more private and secure. Whether you’re a developer, crypto enthusiast, or just curious about Web3 — this post is for you!

State-of-the-art open-source cryptography to protect privacy with Fully Homomorphic Encryption (FHE). Read the litepaper: https://links.zama.ai/litepaper

Who is @zama?
Zama is a company developing open-source tools to bring FHE to blockchain and beyond. Their libraries — like TFHE-rs (a Rust FHE library), Concrete ML (for machine learning on encrypted data), and fhEVM (for private smart contracts on Ethereum) — make this technology accessible to developers. All projects are available on Zama’s GitHub 👉

How does it work?
FHE uses lattice-based cryptography so that encrypted data can participate in computations. For example, with TFHE-rs, you encrypt a number — say, a wallet balance — send it to a smart contract, and it performs arithmetic (like adding interest), returning an encrypted result. Only the key holder can decrypt the outcome. Zama has optimized FHE to make it faster and cheaper — critical for blockchain applications.

What is FHE?
Fully Homomorphic Encryption is advanced cryptography that lets you perform computations on encrypted data without decrypting it. Imagine sending encrypted data to a smart contract — it performs operations (like addition or multiplication), and the result stays encrypted. No one — not nodes, not validators — can see the original data. This solves the problem of public blockchains where all transactions are visible to everyone.
