Nillion describes itself as 'humanity's first blind computer,' a decentralized network that lets multiple parties compute on sensitive data without any node ever seeing the underlying information. Using cryptographic techniques such as multi-party computation and information-theoretic security, Nillion masks data into encrypted 'particles' distributed across nodes, allowing private inference, secure storage, and collaborative computation. The network targets use cases like personalized and private AI, encrypted trading, healthcare analytics, and secure messaging, where data confidentiality is paramount. Nillion's architecture separates a processing layer (compute clusters), a coordination layer (blockchain for payments and orchestration), and a connectivity layer. Its native NIL token, launched alongside mainnet in 2025, powers payments and network coordination. Nillion sits at the intersection of privacy-preserving cryptography and decentralized AI infrastructure.
