Bootstrapping the Cluster

This section explains how to start a Cluster for the first time depending on the consensus choice (crdt or raft) made during initialization. The first start of the Cluster is the most critical step during the lifetime. We must ensure that peers are able to contact each other (connectivity) and

Download and Installation IPFS Cluster

In order to run an IPFS Cluster peer and perform actions on the Cluster, you will need to obtain the ipfs-cluster-service and ipfs-cluster-ctl binaries. The former runs the Cluster peer. The latter allows to interact with it: * Visit the download page for instructions on the different ways to obtain ipfs-cluster-service

IPFS Cluster Architecture

Before jumping in to install and run IPFS Cluster, it is important to clarify some basic concepts. The IPFS Cluster software consists of two binary files: * ipfs-cluster-service runs a Cluster peer (similar to ipfs daemon) using a configuration file and by storing some information on disk. * ipfs-cluster-ctl is used to

Stream Multiplexing

Stream Multiplexing (often abbreviated as “stream muxing”) allows multiple independent logical streams to all share a common underlying transport medium. Libp2p applications often open many independent streams of communication between peers and may have several concurrent streams open at the same time with a given remote peer. Stream multiplexing allows

Publish/Subscribe

Publish/Subscribe is a system where peers congregate around topics they are interested in. Peers interested in a topic are said to be subscribed to that topic: Peers can send messages to topics. Each message gets delivered to all peers subscribed to the topic: Example uses of pub/sub: * Chat

Addressing

Flexible networks need flexible addressing systems. Since libp2p is designed to work across a wide variety of networks, we need a way to work with a lot of different addressing schemes in a consistent way. A multiaddress (often abbreviated multiaddr), is a convention for encoding multiple layers of addressing information

Peer Identity

A Peer Identity (often written PeerId) is a unique reference to a specific peer within the overall peer-to-peer network. As well as serving as a unique identifier for each peer, a PeerId is a verifiable link between a peer and its public cryptographic key. What is a PeerId Each libp2p

Protocols

There are protocols everywhere you look when you’re writing network applications, and libp2p is especially thick with them. The kind of protocols this article is concerned with are the ones built with libp2p itself, using the core libp2p abstractions like transport, peer identity, addressing, and so on. Throughout this

Circuit Relay

Circuit relay is a transport protocol that routes traffic between two peers over a third-party “relay” peer. In many cases, peers will be unable to traverse their NAT in a way that makes them publicly accessible. Or they may not share common transport protocols that would allow them to communicate

Nat Traversal

The internet is composed of countless networks, bound together into shared address spaces by foundational transport protocols. As traffic moves between network boundaries, it’s very common for a process called Network Address Translation to occur. Network Address Translation (NAT) maps an address from one address space to another. NAT
