Nostr

That's a great idea! A lightning channel is sort of like an escrow account; funds committed in a 2-of-2 multisig. Sats could be streamed as things are purchased to build the house. A property record could also be transferred between owners using RGB; it'd be like a receipt or title.

The property title is sort of independent of the building process.

What would be really cool is if we could come up with a way to do nostr based smart contracts. I wrote an algo for a Constuction escrow contract for the Cardano chain a while back.

Customer submits plans => contractor accepts plans and give bid=> customer funds contract=>contractor builds=>customer accepts work=>Contractor gets paid instantly.

Unless: Customer does not accept=>customer funds arbitration contract=>Arbiter makes decision=>arbiter instantly gets paid and customer and contractor get paid what arbiter decides.

At every point, if one party refuses to act, the contract will time out and the money will go the the other party.

Another function was to be added to the contractor side so =>employees get paid instantly.

I thought I saved it to GitHub but now I can't find it. I can't find it on my computer either. If you can find it on GitHub, it's under the name" Project Green Bear". I would forever be grateful!

I never deployed it to Cardanochain because I don't really want to do business in ADA. I was saving to do deploy in Taproot or more preferably, as a Bitcoin L2 to pair with an app.

Fedimints are sort of like it, too, sort of. But neither of them do what I'm looking to do. Not really. I think this is going to be necessary in a world where judges can't order banks to take Bob's money and give it to Jane.

You might be interested in RGB. They have a language called Contractum. It's still very early on, so we don't have good examples of swaps, which is what might be needed for such a thing. There are a lot of tools that might make sense to mix together, like MuSig2 (Taproot multisig), Lightning, miniscript HTLCs, etc. Ideally we'd have something like Sapio or OP_VAULT for what you want to do, but it's unclear if either of those will ever move forward, which require a soft fork. To get around that, things like RGB tokens that are redeemable for Bitcoin might be needed to build more complex contracts.
