Blossom is a spec for a set of HTTP endpoints that allow users to store blobs of data on publicly accessible servers

Blobs are packs of binary data addressed by their sha256 hash

Blossom Servers expose four endpoints for managing blobs

• GET /<sha256> (optional file .ext)
• HEAD /<sha256> (optional file .ext)
• PUT /upload
  • Authentication: Signed nostr event
  • Return a blob descriptor
• GET /list/<pubkey>
  • Returns an array of blob descriptors
  • Authentication (optional): Signed nostr event
• DELETE /<sha256>
  • Authentication: Signed nostr event

BUDs stand for Blossom Upgrade Documents.

See the BUDs folder and specifically BUD-01 for a detailed explanation of the endpoints
