Thanks for elaborating. So if I understand correctly, the trust component is that the lightning server could rug you? What’s the key pair for?
Boltcards are connected to the lightning server as well. What’s the technical difference to the boltcard, as one wouldn’t use the bolt card as a physical way to exchange sats?
Or am I overthinking and it’s just meant to be used like a boltcard but the form factor is different?
yes the formfactor is much better,
you would better think of it as a wallet
which you can give completely to another user !
with a card i never thought of this feature, but now it looks different.
the use of key pairs is better then using eCash in an offline way
because eCash you can just copy !
but with keys you can sign any event on the LN server and you cant easily copy the chip
thats the point... i could use a ntag 213 and just put ecash on the chip
but we know the trade offs right ?
Actually I don’t even know what ntag 213 is. I have not dabbled in physical transfers in Bitcoin yet. Only heard of opendime. So in my head I’m comparing the tradeoffs to that.
Why would I want to sign with the keys on the chip. The chip has its own key pair which is not related to the server right?
the chip can sign an LN server event and send or receive funds,
Hmm I’m not really sure what this means. An explainer video is probably helpful. I feel like I’m missing some information to properly understand what this product would exactly do and why I would prefer it and also why somebody would be willing to take it (so “Sender” and “receiver” tradeoffs)
the goal is offline cash backed by sats !
but yes i will make a video
its just a little work 😅
A video is not a hard thing I’d need, just said that because you mentioned it before. Technically I’m just interested in why would someone want to receive the physical coin. Let’s say I’m a merchant or for that matter anybody who I’m not affiliated with in anyway.
Does having the coin somehow guarantee that I can claw the fund from the LN server? Or is it just a gimmick and I’m overthinking?
the security part is the interesting one
and i guess it could be achieved
right now i would only use as a gimmick
to showcase sats to
normal people
but yes if you give someone the chip, he can withdraw the funds later...
trustmodel should be considered
so it would only work with friends and family
but development on the security of the chip
could boost it to real world cash backed by cyberspace sats !
its just key pairs like in the open dime, only with keys for the lightning network
or just show the balance
everyone wants the chip, trust me
you just need to show people how to use it
i know open dime, but it does onchain payments which dont scale
so i would prefer 2 layer sats: ecash or LN and ecash isnt good enough
