Nostr usage

to get app user's pubkey

• read app user's pubkey by browser extension of NIP-07
• https://github.com/nostr-protocol/nips/blob/master/07.md

to get follow list

• fetch relay list:
  • from bootstrap relays
  • by rx-nostr backword strategy
  • by the filter kinds:[10002,3], limit:2, authors[pubkey you need]
  • with 5sec eose timeout
  • retry with adding the new rules:
    • with 30 sec eose timeout
    • go to the next step after getting the first kind:10002 event
  • basically use only kind:10002 relay list.
    • if there is no kind:10002 event, use kind:3 relay list for fall back.
    • if there is no relay list event, use fallback relays.
  • use a relay list with the newest created_at timestamp
  • remove relays only with "read" tag

to read app user's name, display_name and profile icon

• after reading NIP-07:
  • read kind:0, limit:1, authors:[pubkey]
  • use the event with the newest created_at

    • name:content.name
    • display_name:content.display_name

• fetch follow list:
  • from relay list + bootstrap relays
  • by rx-nostr backword strategy
  • by the filter kinds:[3], limit:1, authors:[pubkey]
  • with 5 sec eose timeout
  • retry with adding the new rules:
    • with 30 sec eose timeout
    • go to the next step after getting the first kind:10002 event
• use a follow list with the newest created_at timestamp

to fetch kind:1 notes with forward strategy

• subscribe kind:1 notes:
  • from relay list
