I noticed that many technical terms were used in posts shared about @zama So I wanted to explain these terms in a short, simple way 👇 🔒 FHE (Fully Homomorphic Encryption) This is the technology at the heart of Zama. Data remains encrypted, but operations can still be performed on it. This means that no one can see the data, but they can still "work" with it. Privacy = protection + data processing 🟨 TFHE (Torus FHE) The type of FHE used by Zama. Thanks to its 'torus' structure, this system is much faster and more efficient. In Zama's open-source libraries, TFHE performs incredibly precise calculations at the bit level. 🟨 HPU (Homomorphic Processing Unit) Zama's specialized processor. This hardware can process encrypted data without decrypting it! This is the biggest step in making FHE practical. So we can call it the 'first processor that works with encrypted data'. 🔐 fhEVM Zama's magic on the blockchain side! You can think of it as the privacy layer of the Ethereum Virtual Machine. Now even smart contracts can work with encrypted data. Zama uses TFHE and HPU as the engine of this structure. 🟨Programmable Bootstrapping As you perform operations in FHE, 'noise' accumulates. Zama solves this problem with a "programmable cleaning" method. In other words, it refreshes the data after each operation and resets errors. 🔑 Key Switching It is necessary to switch between data encrypted with different keys. Zama does this without compromising security. This enables encrypted data sharing between different smart contracts. 🟨 Ciphertexts The data format Zama works on. Each piece of information is a "ciphertext," i.e., an encrypted data block. HPU processes these blocks directly without opening them. This means the data is always encrypted but still functional. ⚡ LUT (Lookup Table) Zama uses predefined table data to speed up certain calculations. This eliminates the need to repeatedly calculate the same operation. Smart speed optimization! 🟨 IOp & DOp Two layers of Zama's processing model: IOp = user operation (at the integer level) DOp = hardware-level operation performed by the HPU In other words, write in human language, let the machine execute in its own language. 🤝 🛡️ KMS (Key Management System) Zama's key management system. Keys are securely stored, renewed, and shared. It comes into play especially in situations requiring multi-factor authentication. 🟨 Threshold Decryption Decrypting a piece of data requires approval from multiple parties. This means no one can access the data alone. A perfect example of decentralization! 🟨 This is Zama's entire vision: Data privacy + computability. fhEVM and HPU are the practical tools for this vision. 🟨 GDPR-Compliant Zama's systems are designed to comply with European data protection laws. Because data is never processed in plain text. 🟨 Zama brings all these concepts together under one roof: 🔹 Fast encrypted computation with TFHE 🔹 Hardware power with HPU 🔹 Blockchain integration with fhEVM 🔹 Security with KMS & Threshold In short, a truly privacy-focused, scalable blockchain infrastructure. #ZamaCreatorProgram
