Selling numbered rocks, you get whatever's next in sequence (opens in new tab)

Feral (judging by the one in the photo).

I'm starting a rock sitting business. Our highly trained staff can look after your rocks while you are out.

Thanks for asking, we're using AWS Bedrock to handle all that

That's actually kinda hard, no?

Say the server has a counter. When you load the page, it's at 57, so it displays that you would be ordering #57. While you're looking at this, someone else loads the page - what number do you show them? If you show 57, then whoever orders first gets it and the other person gets a message "Sorry, not available. Want 58 instead?" but the same thing could then happen to them with #58, too – "Sorry, not available. Want 59 instead?"

So maybe instead you show the 2nd person counter+1, i.e. 58. And you show the 3rd person counter+2, i.e. 59. But what if #59 purchases but 57 and 58 don't? What do you show the NEXT person, 57 or 60?

I'm not saying it's intractable but it merits thought.

Heads up: I purchased the first seven already.

Physical version, no blockchain needed.

I was going to make a joke about NFTs but it seems like reality beat me to it.

Rocks are not physically modified. Sequential numbering exists in our documentation system only - reflected on the Certificate of Authenticity and archive database. The rocks themselves remain in their natural state.

What are you, some kind of quarry robber?

All rocks sourced from private property and licensed commercial operations. No collection from public or protected lands.

Good point.

“All park resources are protected so that all visitors may enjoy them. It is against the law to remove any of the natural (petrified wood, other rocks, plants, animals) or cultural resources (pottery pieces, arrowheads, Route 66 debris), including picking flowers.”

It's funny you ask, I had this exact idea back during the NFT craze. I have an unlimited supply of rocks thanks to the creek in my back yard. Well not unlimited, but there are more rocks back there than people willing to buy them as a joke.

Same kind as the Pet Rock, but worse because it's 2025.

$49.99

I agree - even adjusting for inflation the original Pet Rock [1] wouldn't have cost more than about $25. /s

One order == one rock

Updated. Semantic structure now follows proper heading hierarchy. Appreciate the technical review.

Can you convince someone to buy your rock for $50?

Rock assignment follows purchase order - no reservations possible. Each order is limited to one rock. If you want multiple rocks, place separate orders, but other customers may complete purchases between yours, interrupting sequential numbering. Assignment remains systematic and cannot be influenced by preference.
