The Interplanetary File System (IPFS) is a decentralized file system for building the next generation of the internet. IPFS is a distributed system for storing and accessing files, websites, applications, and data. In this talk, we’ll dive into how decentralised storage with IPFS works under the hood as it builds on top of many long-known, well established techniques and yet is more than just the sum of its parts.

We’ll cover basic working principles like content-addressing and content-routing, followed by the results of an extensive measurement campaign. Answering questions like: How does content-addressing work? Who stores my data if I upload something to IPFS? How do you retrieve content if you only know the hash of it? How fast is that process?
