Libp2p

libp2p is a modular networking framework bundled together as a full stack of protocols for peer-to-peer systems. It is the product of a long and arduous quest into the internet's network stack and all of the plentiful peer-to-peer protocols of the past. Building large-scale peer-to-peer systems has been complex and challenging in the last twenty years and libp2p is a way to fix that. It is a "network stack"—a protocol suite—that cleanly separates concerns and enables sophisticated applications to use only the protocols they need without giving up interoperability and upgradeability. libp2p grew out of IPFS into an independent project designed to give any project state-of-the-art peer-to-peer capabilities.
