Raretoshi is a platform for NFTs on Liquid sidechain of Bitcoin thats been in operation for a few years.

Liquid also has support for general asset token issuance.

And if for some reason an org wants to spin up thair own side chain, they can host their own instance of Elements which is the foundation of Liquid.

What isnt clear to me is just how much permanence people want and need. Bitcoin may offer the most permanent, permissionless, censorship resistant protocol but its not an efficient use of blockspace. If anything, ordinals reveals that scarce blockspace may be underpriced or underutilized at times.

I think the likes of ordinals naturally get priced out over time as people and orcs opt to pay market rates for onchain transactions. Just as miners are an adaptive buyer of last resort for stranded energy, ordinals will fill the space of unused blockspace. Will this influence base prices? Absolutely. Energy generation can be built, but blockspace cant. And given that Bitcoin onchain transactions in part compete with FEDWIRE, we still have a ways to go on cost equilibrium.
