Good shit 😅

Can I read somewhere more about this project?

The biggest retail in Czech Republic accept bitcoin.

Thanks @Khunsa, I appreciate your interest — but at the moment I don’t have the bandwidth to dive into it.

I just have a few quick notes:

• At first glance, it’s not clear to me what problem the service is solving. I think the most effective next step would be to get your first paying customer (or use it primarily for yourself) and serve them well. It’s not necessarily important to have a perfectly clear website if it serves the target audience effectively.
• I wasn’t able to register — after entering my email, I got an “Invalid credentials” error.
• If this is a Bitcoin-related service, it would be nice to have Lightning login support.

Wishing you lots of success!

There are still unofficial but working solution with Trezor (top hardware wallet)

Prediction markets are not the same as random gambling

Not yet. But I’ll do it 👍

Top quality and third cheapest.. Visit the Prague 🍻

Valid concerns.. I will still keep an eye on it.

Are you really familiar with the Ark design? You are not sending bitcoin elsewhere and you are always able to withdraw the funds without permission.

I'm not commenting the marketing thou.. it's a bit suspicious.

Ark is bitcoin just like Lightning..
Liquid, statechains, drivechains, etc. are not bitcoin

You can use the only HWW with native coinjoin:

Yes

Yes, but you are talking about fee rate. Fee is not in fractions of sats

• By fee I mean sum_of_outputs-sum_of_inputs
• By fee rate I mean fee/tx_vsize

They just ignore it

Exactly. And this could even help with the security budget because on-chain might become even more accessible. It's kind of free money for miners actually.

True

Good joke :-)

But the idea doesn't introduce fractional sats. It's very delicate change than any node runner can do.

This doesn't help with scaling. But it could bring more granularity to fee market and keep it public.

I don't see the problem with the fraction. You still send whole amounts of sats. Fee rate is only a tool to compare the absolute fees.
So in the example above, you could relay simple transaction (141 vB) for 2 sat →  0,014 sat/vB
