GM.
I am being woken up, by tiny creatures from my own bloodline, who else?
But with the file I could do an offline payment?
Or rather one were I transact offline and then receive payment on Lightning or did I misunderstand the concept?
I've implemented a BitStream proof of concept by Robin Linus in Cashu for atomic swaps between files and Lightning payments.
Atomicity is achieved via a "Nutbond" Ecash contract which can be challenged if the downloaded file doesn't decrypt right.
An explainer and demo video is linked below.
How it works:
- Clients requests download
- Server sends encrypted file, Lightning invoice & Nutbond
- Client verifies bond and pays LN invoice
- Client decrypts file with LN preimage
- If decrypt fails, client challenges Nutbond & gets refund
Some notable differences to the original proposal:
- Nutbonds are issued for each user, not per file
- Bond doesn't burn but acts as a refund to user
- No Merkle trees yet. Next logical step. Vibes well with BitTorrent.
- Bond is Ecash. Payment is on LN, could also be Ecash.
This took me a few hours to implement showing how easy it is to experiment with new contracting primitives in Cashu.
Bitcoiners are coming up with beautiful solutions for practical problems. Special thanks to Robin for sharing his cool ideas with us. Love the energy!

My head is trying to wrap itself around fully around what you just said⊠so you mean we could essentially make fully offline Lightning payments?
Oh no⊠but thanks to nostr:npub1wxl6njlcgygduct7jkgzrvyvd9fylj4pqvll6p32h59wyetm5fxqjchcan at least zapping on nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 is working again.
Wird #Bitcoin uns vor der Demografischen Bombe retten?

im Park gesessen um genau dieses Thema zu besprechen.
Schaut gerne mal rein.
Liebe Freunde,
es ist so weit. Bitcoin Nation ist nun auch auf Deutsch bestellbar.

If anybody wants to know more about my book Bitcoin Nation and how bitcoin and demographics will reshape states, please reach out.
I am open to come on podcasts and conferences. 
I donât want one. I would grudgingly accept one if I consider it necessary.
If we need a fork (which Iâm not fully convinced of), then OP_VAULT should be it.

Does #Bitcoin fix everything?
How will states change on a #Bitcoin standard?

To celebrate 15th anniversary of the #Bitcoin Whitepaper, my new book Bitcoin Nation is released today.
If you want to know how Bitcoin fixes states, you can get it on Amazon:
Launching a bioweapon and then convincing people (sometimes by force) that an even stronger bioweapon protects them is a next level psyop. You have to grant the Malthusian elites that much. nostr:note1v3g6tpsh8jy8m5nuvff5qvzlafag5j4gfksr3r8pak7mmcx50hsql0kcqt
