In order to understand how the internet actually works you must let go of the idea that the internet is a single thing or a single network. Networks within networks & networks layered over networks
Key Example of an overlay network: Voice over IP, which developed at a time when most IP traffic was being sent over the old voice network. ... voice signal (audio) encoded as digital information, which was then encoded as audio signals, which were then sent over copper wires through physical infrastructure designed for voice traffic. Eventually (with the rise of optical fiber networks and wireless networks), which are designed for digital content, the networks became flipped -- phones now run over VoIP.
You need:
- "The Cables" Physical-layer Connectivity
- "The Receivers" Application-layer Connectivity: Networking Stack
- "The Rumor Mill; The Signaling Network" DHTs, Data Interchange (bitswap) & Routing
- (Mavens and Connectors)
- "The Languages" - data structures
- "The Pubs and Libraries" -
- Net Neutrality
- Municipal Networks ... crushed by telecoms spending billions of dollars to discredit the idea in the court of public opinion. Meanwhile, comcast resells its customers' wifi bandwidth.
- "Mesh" Networks
- Reference: Master Switch... independent radio, independent telephone operators, etc.
- libp2p
- Wire-level encryption
- IPFS Address Scheme vs. bittorrent address scheme
Capabilities-based Encryption
- Tahoe-LAFS
- keybase
Data Privacy, HIPAA, etc
- Why isn't Social Data reusable? ... SoLID
- when I sign up for a new social media platform, why can't I import all my existing posts from other platforms? Email works that way (I can migrate my emails), why doesn't social media work that way?
"The Signaling Network; The Rumor Mill" -- passing the data around with DHTs, Data Interchange (bitswap) & Routing
Example: when I visit facebook, I'm dynamically loading information from their giant database. The contents of that giant database are constantly changing as people add new information. If we use a content-addressed approach, that means each address points to something immutable -- it can't change. Does that prevent us from having data that changes? ANSWER: immutable data structures are actually the ideal way to handle data that changes rapidly...
- pubsub
- blockchain
- IPNS
- fall back on centralized (or semi-centralized) systems -- DNS, databases, etc.
- real-time feeds of data
-- in an immutable context, how do I update a file and tell people which version is the current version? -- example: IPFS livestream -- example: github -- example: patchwork pubs -- example: SLEEP versioning -- example: Holochain
