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.

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
