Thank you for raising awareness of this!

Trezor is transparent with these discoveries: https://trezor.io/learn/a/past-security-issues

I've updated the proposal. See: https://github.com/hynek-jina/Hynek/blob/main/blog/Last%20mile%20transactions.md

I didn't want to go into technical details yet.. but imagine that the defense transaction looks similar to commitment transaction in lightning.

In our example there will be two outputs:

Alice can create another transaction where Bob has nothing.. She will loose slightly more, but Bob will be punished.

I don't know what would be the best use case.. I had in my mind option to offer cheap self-custody to newcomers.

Nice, but the seconds are actually nonsense 🙂

Difference in price could be caused by transaction costs. Imagine being able to transfer for free via Wallet of Satoshi or costly permissionless…

I would probably cash out small portion of the stack. If it isn’t feasible then rather keep everything in real bitcoin.

Lightning doesn’t scale in terms of user count. It’s necessary for regular payments, but as of now there can’t be more than 20mil self-custody users. (Assuming 1 transaction per month)

I'm trying to research this as well. These concepts are hard to understand.. but here is my current list:

That X shit doesn't allow me to message you..

How will bitcoin scale?

I believe that Lotes could serve your use case... #307757

But I still don't like liquid. Mainly because you cannot simply switch it into real bitcoin.. It's not for end users...

Juraj Bednar has published interesting article about this topic months ago: https://juraj.bednar.io/en/blog-en/2023/05/07/expanding-the-lightning-network-to-serve-billions-a-quick-win-strategy/

I have translated for this purpose this leaflet into my native language: https://bitcoinforlocalbusiness.com/

Cool idea 🚀



I would like to share similar experience. There is a club in Czechia (Bitclub) where you can pay with bitcoin of course. But when you pay in fiat the club owner writes this amount on a blackboard and next customer can withdraw that in bitcoin (1 CZK ~ 120 sats). If he rejects the amount is still increasing with every new fiat purchase until some nocoiner collects it.

Here is similar solution with NFC cards: #307757

Would you like to cooperate? 🙂
