DAY 1 ZAMA, Fully Homomorphic Encryption on Ethereum @zama Imagine if smart contracts could process your data without ever seeing it.A world where DeFi apps could run credit checks, DAOs could vote, and wallets could transact all without revealing a single private detail. That’s the future Zama is building, and it begins with Fully Homomorphic Encryption (FHE) on Ethereum. Privacy remains one of the hardest unsolved challenges in blockchain technology. While Ethereum provides transparency, that transparency comes at the cost of confidentiality. every transaction, balance, and contract variable is visible to everyone. Solutions like Zero-Knowledge Proofs (ZKPs) and MPC (Multi-Party Computation) offer partial relief but fall short of enabling general purpose private computation directly on-chain. In essence, Ethereum’s greatest strength transparency, has become its biggest limitation for privacy-centric use cases. Zama’s mission is to make privacy programmable by introducing a framework that lets developers write smart contracts operating directly on encrypted data. Instead of relying on off-chain computation or custom privacy layers, Zama brings Fully Homomorphic Encryption to the EVM, creating the FHEVM, a confidential execution layer compatible with Solidity. Fully Homomorphic Encryption (FHE) is a form of encryption that allows computation on ciphertexts, meaning data remains encrypted even while being processed. This enables a smart contract to perform mathematical operations, comparisons, and logic flows on encrypted inputs and outputs, without ever decrypting them. Zama’s FHEVM integrates this capability into Ethereum compatible environments, allowing developers to: use encrypted data types, perform encrypted arithmetic and logic via the FHE library, deploy confidential contracts that maintain state privately, request controlled decryption through secure oracles Zama achieves this through several core innovations like FHEVM Architecture, Encrypted Data Types, Encryption Proofs & Decryption Requests , Homomorphic Complexity Units (HCUs) and Compatibility Layers By embedding FHE into the EVM, Zama has demonstrated End-to-end encrypted computation, Confidential Voting, Private Transfers, and Encrypted Counters, OpenZeppelin Confidential Contracts (ERC7984), Developer SDKs and Hardhat Plugins. Zama’s solution is the FHEVM that transforms Ethereum into a privacy preserving computational platform without compromising its decentralized principles. Developers can now build dApps that protect user data natively, conduct encrypted operations in DeFi, gaming, identity, and healthcare, ensure compliance by controlling when and what gets decrypted. It redefines the smart contract paradigm, not just “trustless,” but also “private by default.” Conclusion Zama doesn’t just introduce another privacy tool it fundamentally shifts how Ethereum thinks about computation. By making data confidentiality a programmable feature, it opens doors for regulated DeFi, encrypted identity systems, and real-world financial interoperability, all on public blockchains. #ZamaCreatorProgram @randhindi @farcaster
