Lightning has in my opinion a better user experience then on chain payments. In most cases the fee is lower and the payments are almost instant settled. One of the downsides of lightning, a specially compered to on chain, is the security.
Do you think the security of lightning will increase to a level where it will become more common to also use lightning for storage? Or even to use lightning to make some profit form stored bitcoin (stored in channels) in a safe way?
Are you working on security products for lightning?
We are currently working on a concept that will bring a "send-only" LN channels to Trezor. That way, you can have a LN channel fully protected by a hardware wallet but at the same time completely secure while being offline.
reply
Will this be a channel that you can have next to other LN channels? So that you can also have a ‘hot’ LN channel to receive payments and make small transactions.
Are this ‘send-only’ channels meant to be build in to existing LN clients or will this require a special app?
reply
This will be implemented in Trezor and Trezor Suite first.
But since our implementation will be open-source as always, any LN client could integrate this if they want and other HW wallets might pick-up the idea as well.
reply
whoa, need to learn more about this concept.
can you elaborate or share any blog posts that explain how send-only LN channels work?
will users still need to operate a lightning node for send-only LN channels to work?
reply
There is nothing to share yet, because this is still a work in progress. But essentially Trezor acts like a LN node which never receives a payment. I promise to share more once we have more details.

can’t wait to see the product launch announcement on stacker news when it’s ready!

So the idea is that if you never receive on a channel then you don't need a watchtower, right?
Could this be used without internet access but having network connection to the recipient (assuming the recipient is the other end of the channel of course)?
reply
Yeah, right, you don't need a watchtower while being offline.
could this be used without internet access but having network connection to the recipient
That's the general idea, but we need to examine this further, whether there are some issues with that.
