`draft` `optional` `author:staab`
Relays may support the `COUNT` verb, which provides a mechanism for obtaining event counts.
Relays may support the verb `COUNT`, which provides a mechanism for obtaining event counts.
## Motivation
Some queries a client may want to execute against connected relays are prohibitively expensive, for example, in order to retrieve follower counts for a given pubkey, a client must query all kind-3 events referring to a given pubkey and count them. The result may be cached, either by a client or by a separate indexing server as an alternative, but both options erode the decentralization of the network by creating a second-layer protocol on top of Nostr.
