Plain-language guides, no hype
Peer-to-peer, explained from the connection up

What P2P Vine covers
P2P Vine covers peer-to-peer technology in practice: file sharing and sync, WebRTC calls, decentralised storage and the privacy trade-offs that come with connecting directly to strangers.
How peers find each other
Trackers, distributed hash tables, NAT traversal and why a direct connection is harder than it sounds.
P2P you already use
Video calls, OS updates, file sync and more quietly run peer-to-peer. We show where and how.
Privacy in a swarm
In most P2P systems your IP address is visible to the peers you connect to. What that means and how to reduce it.
Decentralised storage
Content addressing, IPFS and blockchains: what changes when data is found by its hash instead of its location.
FAQ
Questions parents ask first
Is peer-to-peer file sharing illegal?
No. The technology is legal and widely used for software updates, backups and open-source distribution. Sharing copyrighted material without permission is what infringes.
Can other peers see my IP address?
Usually yes. A direct connection needs an address to reach, so peers in the same swarm or call can typically see the public IP you connect from.
