Ability to display held inscriptions publicly

[casey]

From @haribosan's comment in #784:

Collectors that want to make their collections public are going to need their own identifier too, something that links to all their inscriptions. Not sure if there are more elegant ways to achieve this but a static bitcoin address could easily do the trick: collectors can re-use the same address each time they add a new inscription to their collection, thus making all their art publicly fall under the same ID / owner. In this context, address reuse is clearly a non issue. What could be an issue is the ability for anyone to spam known collectors by sending them bogus inscriptions. But I believe having a prime ordinal equivalent for collectors is a very important feature to have.

Showing off collections of owned NFTs is something that users like to do.

There are a few ways we could do this:

• Make the wallet reuse addresses, so you can trivially see which inscriptions are owned by the same person.
• Allow the user to publish their extended public key to the server, so the server can see all addresses that a given wallet has, and thus all the inscriptions it owns.
• Allow the user to do something like #1156, where they use an inscription in a transaction with their prime inscription.

I echo the importance of allowing users to have a public wallet/collection.

A potential solution to the spam issue is a "HIDE" feature in the UX of ordinals.com (or other sites), which allows the owner of a wallet to hide inscriptions.

Or perhaps you could mark them as spam at a higher level, by signing, such that all sites could recognize them as spam and opt to hide them.

Edit: one cool thing about getting spammed with inscribed sats is that you can spend them!
