Privasea

Privasea is a decentralized privacy computing infrastructure focused on Fully Homomorphic Encryption (FHE). Its core business includes the DeepSea AI Network, a decentralized computing network that enables AI models to train and infer directly on encrypted data, and FheID, a biometric identity verification solution that uses FHE to match facial features without exposing raw data. The key narrative is "data usable but invisible" — solving the dilemma where AI development demands massive data while privacy regulations restrict data sharing. The market pain point is that traditional AI requires plaintext data, creating privacy leaks and compliance risks, especially in finance, healthcare, and identity verification. Privasea's solution allows data owners to retain full control while contributing to AI computation.

In the past six months (2026-02-28 to 2026-08-29), Privasea launched its mainnet in February 2026, enabling public access to the DeepSea network. The PRAI token was listed on major exchanges including Gate.com, improving liquidity. The team also released an upgraded FheID SDK for mobile devices, enabling privacy-preserving face authentication for Web3 wallets and traditional fintech apps. Ecosystem partnerships expanded to include several DePIN projects and AI data marketplaces. However, the PRAI token price experienced significant volatility, dropping over 90% from its May 2025 peak, reflecting broader crypto market corrections and early-stage project risks. Despite this, developer activity on GitHub remained steady, with regular protocol updates focused on reducing FHE computational overhead.
