Merchants lose 20-30% of profits to 3% card network fees
βSo when a seller uses fiat accepts fiat payments, there's a 3% fee taken by the networks. And on the consumer side, you typically see that, you know, maybe on a receipt, you are, like, upset about the fee that you got charged or maybe you see a sign at a merchant, you know, tacking on a fee. But the thing I like to bring this back to is that for a business that maybe on a great day makes 15% margin, and maybe on a medium day is a 10 margin and maybe has some bad days, 3%, we just talked about 20 to 30% of their profits. That 3% is computed on the ticket size, not their profits.β
Bitkey buyers often purchase multiples to gift to family
βWe've been doing the key giveaways for, I think, over a year now, TFTC, and that is the number one use case the winner uses it for. They say, hey. I've got one already. I'm gonna give it to my my dad or uncle who hasn't moved it off the exchange yet. We saw people buying five, ten plus big keys and gifting them to others and and saying to that person that they've been, you know, talking about getting off the exchange with, there's finally something that you could use to do this.β
Recovery edge cases are the invisible complexity of self-custody
βThe the thing I'd highlight here is that the set of things that can happen to people when they're self custodying their coins is unbelievably large. Like, maybe you lose your phone, you lose and you lose your hardware. But then they start to get to things like, what if I lose both? And we have a recovery contact solution for that. They get to questions like, what happens if Blocko's out of business, and is it making Viki anymore? And we have our emergency exit kit for that. The team has spent so much time looking closely at making all of those flows rebut really robust.β
Wrench attacks are accelerating globally and remain unsolved
βAnd I think we see that with both the the attacks that we've seen in France and also lots of the attacks we started to see in The United States. It feels like there's an acceleration. I think pretty clear there is one and, Jameson Lopes, you know, chronicling of all of these, of course, can help help put some of the numbers behind that. We think that, you know, even if you're holding a lot of Bitcoin, most people there's a lot more important things in life that are sudden if they're suddenly threatened, like, it doesn't matter what kind of practicing you did with lying about your balance or, you know, hoping an attacker hadn't done their research beforehand.β
Bitkey's new hardware wallet adds a screen for on-device verification
βWell, I think this was the biggest point of feedback at the old BitK that I always got. There's no screen. Like, I need to be able to verify the receive address or the seven address. And I think you guys did an incredible job, answering that question of, like, when when screen, and if so, how? I mean, it takes up the the full bottom of the wallet.β
Time-locked vaults could neutralize physical coercion attacks
βWhat we really want is to set up a situation where the Bitcoin just can't actually move right away. We think that velocity is one of the best possible tools that we can give people. Meaning that in some of the attacks and and in in almost all of the attacks, I think that that Jameson is is crying. They're less than twenty four hours. Their attacker showed up, and, you know, they weren't putting themselves at risk trying to hold people hostage for a week or a month. And so a lot of our focus is on how can we provide a really safe and easy to use time lock capability that would allow people to set some parameters around how fast their Bitcoin can move.β
Seed phrases are a vulnerability during physical attacks
βYeah. And actually on that topic, one thing we realized while we were looking at this is that Viki might be uniquely suited to design for it. And the reason for that is actually one that I think is a little bit controversial, which is that Vicky doesn't use seed phrases. And the re the reason it's uniquely suited to rent or tax is because in that setting, seed phrases are a vulnerability. They're too they're too instant. They're too portable. Like, somebody can take and leave with this, and it's very hard to protect it.β
Chaincode delegation removes privacy trade-offs in collaborative custody
βAnd with Chaincode delegation, we wanted to take a huge step, really for Vicky, but also for the industry in terms of the that type of trade off. We wanted to be possible to get the benefits of leaning on somebody to hold a third key for you, all the recovery and safety benefits while not having the same privacy downsides. And so Chaincode delegation, uses some relatively deep cryptographic magic. Basically, to, to to to make it so that, Viki servers aren't sitting there with that output or with that descriptor of the wallet, knowing the balance, knowing the history.β
