IPFS: How the Interplanetary File System Works & Why We Need It

Have you ever wondered what would happen if the servers for YouTube or Wikipedia suddenly went offline? Today’s internet relies on centralized server farms, making it vulnerable to censorship and outages. In this video, we explore a potential solution: IPFS (Interplanetary File System), a project aiming to make the web completely distributed using a peer-to-peer network. What you will learn in this video: We break down the technical differences between how we currently access the web versus the IPFS approach: • Location vs. Content Addressing: Learn why the current web asks where a file is (IP address), while IPFS asks what the file is using unique hashes. • Security & Efficiency: Discover how using hashes ensures files haven't been tampered with and allows for data deduplication. • How Files are Stored: A look at IPFS objects, how large files are split into 256kb chunks, and how versioning ("Commit objects") works similarly to a blockchain. • The "Interplanetary" Connection: Why is it called "Interplanetary"? We explain the difficulty of browsing the web from Mars due to signal latency (4 to 24 minutes) and how IPFS caching could make an interplanetary internet possible. The Challenge of Availability: While IPFS is powerful, files can become unavailable if nodes go offline. We also discuss Filecoin, a blockchain built on top of IPFS that incentivizes users to rent out their hard drive space to keep files online and replicated. Real-World Examples: See how IPFS has already been used to fight censorship, such as restoring access to Wikipedia in Turkey, and powering decentralized video platforms like DTube. Question of the day: Do you think a decentralized web can truly replace the tech giants we use today? Leave a comment below!
