Freenet and Hyphanet aren't blockchain, although the original Freenet did pioneer the cryptographic contract back in 2000 (we called them "signed subspace keys"), which a few years later would form the basis for Bitcoin.

Freenet is designed to be a general-purpose platform for building and distributing decentralized systems like group chat[1], social networks, search, really anything that people use the Internet for today. Some people think of blockchain this way but blockchain is much more specialized (eg. group chat on blockchain wouldn't scale).
