Full Title

The InterPlanetary File System (IPFS) is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a Global Namespace connecting all computing devices.^[1]

Context

• IPFS was first deployed in 2015 and grew by word-of-mouth as a replacement to HTTP for static content.
• It allows users to host content as well as to search for it.
• If users do not wish to host content, they can access IPFS by a public gateway.

Installing

For Windows using chocolatey.

> choco install go-ipfs
> ipfs init
> ipfs daemon

By default the client looks for a daemon at http://localhost:5001. This can be overridden by either setting the environment variable IpfsHttpUrl or initializing the client with an URL.

// js-ipfs likes this address
static readonly IpfsClient ipfs = new IpfsClient("http://127.0.0.1:5002");

Test to see if the daemon is running by typing this in your browser.

http://localhost:5001/ipfs/bafybeianwe4vy7sprht5sm3hshvxjeqhwcmvbzq73u55sdhqngmohkjgs4/#/

Solutions

• the [Sidetree] protocol uses IPFS to insure that Identifiers are unique.
