IPLD Data Structure

• Nodes in the Noosphere graph are called memos.
• A Memo is an open-ended data structure, containing 3 things.
  • Body Content
    • It can be any freeform content.
  • Inline Headers
    • Metadata about the content.
  • Parent Pointer
    • References the previous version of the memo.
• A sphere is a collection of notes/memos.
  • Every sphere has an associated public key.

Name System

• First prototype was a smart contract-based system, but it was too expensive.
• Now: DHT via libp2p’s kademila
• Main Challenge
  • Peer Quality / Availability
• IPNS isn’t being used. Never tried because they assumed it would be slow for this application.
