Overview of InterPlanetary File System - IPFS with (Examples with Command line & Brave Browser)
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. Intro 0:00 Why IPFS? 2:00 Explain the original web model and the limitation * Content addressing instead of location addressing * decentralized content distributed among peers Content 3:30 * Content is hashed as CID * Content is immutable each update generates new CID * Content addressing Routing 4:30 * Distributed Hash Table (DHTs) maps CID / Peer IP address * DHT server hosts content and DHT Publishing Content 6:30 * New Content that you want to share on ipfs * hash the content creating new CID * Update your local DHT CID / your ip address * DHT will be updated to all the content peer (NOT the CONTENT) * People searching for your CID will be connected to you and only you. Consuming Content 8:48 * ipfs client (dht client) want to consume Ipfs://cid/ * ipfs client consults its local DHT table to see where this CID is located, gets back a collection of IP addresses * client connects to some or all the peers found hosting that CID * client downloads chunks of the content from each peer so it speeds up * Once the client has the content it is now also updating its local DHT table that it now also hosts that CID (if it supports being a DHT server) * New updated DHT is propogated across peer IPFS Overview (Digrams) 11:30 Demo 13:45 More Information 18:30 Immutable Content * if Content gets updated changes URI how do I inform the user? * hash the public key of the user instead and share that Brand new Client/server * I know nothing about the network (Bootstraping) * you will be bootstrapped with a collection of ip addresses to start you up. More * IPFS gateway * IP Name server * Solve content * Deleting Content( once other node hosts it no way to delete it from their network) NAT traversal Resources https://datatracker.ietf.org/meeting/interim-2020-dinrg-01/materials/slides-interim-2020-dinrg-01-sessa-an-overview-of-the-interplanetary-file-system-ipfs.pdf https://www.youtube.com/watch?v=K4Usud4g4iY&feature=youtu.be&t=1008 https://twitter.com/hnasr/status/1353548949945163776?s=21 https://docs.ipfs.io/conce 🎙️Listen to the Backend Engineering Podcast https://husseinnasser.com/podcast 🏭 Backend Engineering Videos https://backend.husseinnasser.com 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC 🏛️ Software Archtiecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9 📩 Messaging Systems https://www.youtube.com/playlist?list=PLQnljOFTspQVcumYRWE2w9kVxxIXy_AMo Become a Member https://www.youtube.com/channel/UC_ML5xP23TOWKUcc-oAE_Eg/join Support me on PayPal https://bit.ly/33ENps4 Join our Thriving Backend Community on Discord https://discord.com/invite/CsFbFce Stay Awesome, Hussein
