Privacy blockchain project Nillion has raised $25 million in a funding round led by Hack VC, with Arbitrum, Worldcoin and Sei also participating. Nillion is trying to attract projects at the intersection of blockchain and artificial intelligence (AI) that need to securely share and store large amounts of data. Blockchain converges with AI by attempting to decentralize ownership and leverage the data required by AI engines, preventing it from being dominated by a few centralized entities.
