basically like bittorrent but the entire network is just one swarm and blocks are deduplicated and everyone keeps the stuff they accessed for a while so peers near to them can fetch it from them
it also has a dht, a pubsub like system for fast message propagation and changeable content and is built to be future proof on the protocol level (everything is modular and self describing and can be swapped out)
oh and also everything can link to everything by its CID (content identifier)
