The IPFS Protocol Explained with Examples - Welcome to the Decentralized Web

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.

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 i
