Imagine if vertex search by nostr:nprofile1qqs0dqlgwq6l0t20gnstnr8mm9fhu9j9t2fv6wxwl3xtx8dh24l4auspz4mhxue69uhkzat5dqhxummnw3erztnrdaksz9nhwden5te0d4kx26m49eex2ctv0yhxcmmv9uq3gamnwvaz7tmjv4kxz7fwv3sk6atn9e5k7dj6rpa would accept ecash. A user could go to following.space which could load their NIP-60 wallet containing nuts. Without registration or even doxing your pubkey, the user could search for usernames and pay the search DVM like 1 sat worth of ecash in each search request.

The user happy, the pip happy, the nostr happy, everybody happy.
