Nillion

Nillion is a secure computation network designed to decentralize trust around confidential data through privacy technologies. It supports AI model training and inference without exposing the underlying data, including private inference for large language models and retrieval-augmented generation.

Within Web3, Nillion provides infrastructure for private AI applications, DePIN systems, and decentralized services coordinated through a blockchain layer.

Its AI foundation is technically substantial: the network uses multiparty computation and other privacy-enhancing technologies to protect computation cryptographically. GitHub repositories and research on private large language models support its focus on secure AI.
