" summary

Survey of protocols focuses on practical choices: libp2p demo shows three nodes using a TCP transport, SECIO encryption, mDNS discovery and a pubsub channel called "yelling", implemented in a few hundred lines and successfully exchanging messages. Examples include IPFS (nodes immediately see ~100 peers), scuttlebutt (offline-first, pub/seed model), dat/Beaker and Ethereum; an experimental IPFS node transferred about 5 GB in 8 hours, highlighting bandwidth and privacy trade-offs.
