Fhish is a Fully Homomorphic Encryption (FHE) Rollup Stack built to bring true on-chain privacy to the Initia ecosystem. In today’s blockchains, everything is transparent — which limits real-world use cases like private voting, confidential DeFi, and secure identity systems. Fhish solves this by enabling computation on encrypted data. Your data stays private not just in storage — but even during execution. 🚀 What this demo shows Spinning up a private rollup using Fhish CLI Deploying relayer and gateway infrastructure Connecting a custom RPC to Initia explorer Running a private voting app Executing encrypted smart contract calls Viewing transactions where both method and data remain hidden 🧠 How it works (simple) Data is encrypted in the browser using WASM Encrypted payloads are sent to the smart contract Contracts compute on encrypted values using FHE Gateway stores ciphertext off-chain (gas efficient) Relayer securely processes and returns results ⚡ Key Features Fully private computation on-chain 100% self-hosted (no external decryption services) Gas-efficient via off-chain ciphertext storage Built for Initia’s Interwoven Rollup architecture Developer-friendly CLI + Solidity interfaces 🛠️ Tech Stack Rust (tfhe-rs), WebAssembly Initia SDK, MiniEVM Hardhat, Ethers.js Docker-based infrastructure 🔗 Links Main Repo: https://github.com/fhish-tech/fhish CLI: https://github.com/fhish-tech/fhish-cli Gateway: https://github.com/fhish-tech/fhish-gateway Demo: https://github.com/fhish-tech/fhish-demo WASM: https://github.com/fhish-tech/packages/fhish-wasm
