P2P Community Hub 🇮🇳

A vendor-neutral home at @EFDevcon for the people who build and maintain Ethereum's networking layer, and for anyone curious about it.

Our logo shows the ideal: everyone connected, nobody in charge. How real networks get close to it is the interesting part.

What would you like to understand better?

We’ll explain more in person at the P2P Community Hub, @EFDevcon 8, Mumbai, Nov 3-6.

In a network of 6 where everyone is connected, one new person doesn’t add 1 connection. They add 6.

Our logo is a tiny example: 6 peers, 15 lines. Here’s how that works

So real P2P networks don’t connect everyone to everyone. Each peer keeps a handful of connections, and messages hop from neighbour to neighbour until they arrive.

That’s the green line in our logo: one message finding its way across.

Now back to the opening. A 7th peer joins. They need a line to each of the 6 already there, so we go from 15 to 21. That’s 6 new connections, not 1.

3 peers: 3 links
6 peers: 15
12 peers: 66
100 peers: 4,950

Links grow much faster than peers.

Each dot is a peer, meaning a computer or person on a network. Each line is a direct connection between two peers.

Every peer is connected to every other, and nobody sits in the middle.

If you’ve ever wondered how that works, or why people care, our Community Hub at Devcon 8 (@EFDevcon) in Mumbai, Nov 3-6, is a good place to learn and ask.

Over the next two weeks we’ll share the agenda and a few basics.

Follow along.

Ever wondered how a network can work with nobody in charge? That’s P2P

P2P means peer-to-peer: networks where computers talk to each other directly instead of going through a central server
