The privacy blockchain project Nillion raised 25 million USD in a funding round led by Hack VC, with participation from Arbitrum, Worldcoin, and Sei. Nillion is trying to attract projects at the intersection of blockchain and artificial intelligence (AI) that require secure sharing and storage of large amounts of data. The blockchain aims to integrate with AI by attempting to decentralize ownership and utilize the data needed for AI engines, thereby preventing dominance by a few centralized entities.
