   • Where this pubkey generally writes, and where it generally reads mentions
   • Supported NIP numbers for one relay
   • A direct message archive
   • Payment for relay storage
   Answer 1

   Where this pubkey generally writes, and where it generally reads mentions

   NIP-65 is a replaceable kind:10002 event with an empty content field. r tags mark write relays and read relays.

2. Where should a client look for notes someone authored?

   • That user's read relays
   • A single main relay shared by everyone
   • That user's write relays — their outbox
   • Only relays listed in your own kind 0
   Answer 2

   That user's write relays — their outbox

   When downloading what someone authored, clients SHOULD use that user's write relays. Mentions are the other direction: their read relays.

3. Why does the NIP tell clients to keep relay lists small?

   • Small lists are easier to sell
   • Relays reject lists over one URL
   • Kind 10002 cannot store more than one tag
   • About 2–4 relays of each category. Huge lists recreate connecting to everything
   Answer 3

   About 2–4 relays of each category. Huge lists recreate connecting to everything

   Clients SHOULD guide users toward about 2–4 relays of each category. A huge list brings back the flood the outbox model was meant to leave.
