So, is anyone working on a #marketplace features for nostr?

What features would be useful?

What principles should it use?

A marketplace note should probably have a tag like #marketplace or #auction or #nostrbay or ...

A tag for #buy #sell #trade

Then we need tags for values. Like #price:[number][sats] or for some time maybe even [usd] [eur]. Other similar tags would be #pieces:[number] or #weight:[number]

Active tags for bids in auctions. Should bids come with zap collateral being sent to the auction so that there is some weight to bids?

With this in place and corresponding search/filter tools in the nostr clients this would be a great decentralized place to trade anything.

Of course the tags would be displayed as icons or small widgets.
