Huh, I recognize the headline is using the same terminology as the post:

Casa Inheritance is available worldwide and accessible for every investor.

Strange to overload that term (Casa the company has its own investors) instead of saying the feature is available to all paid members/clients/users. Despite the needlessly confusing language, it’s cool they’re offering inheritance more widely now.

So Casa have 2/3 keys?

Of course not, that would make it custodial.

The mobile keys are only held by the client and their designated recipient.

For the ultra paranoid, we offer the option to use a second hardware key in lieu of a mobile key.

What happens if you sign for the the paid plan to use the multi-sig inheritance, but then stop paying one year. How do you export or recover the custody?

will Casa post more on this platform?

Does the inheritance product involve a closed source Casa mobile phone wallet?

This is a very good point.

Mr @lopp, as a potential customer (I like the product), is it really necessary for me to sign up to draconian Google or Apple T&Cs / accounts to download your app?

Why no repo, or at least an APK download?

Yes, it is one of the biggest weaknesses in Casa's design: too much trust is required for the Casa app, particularly the mobile key generated by the Casa app.

What's ironic is that they've somehow turned this weakness into a feature: leveraging the mobile key for an "easy-to-use" inheritance protocol. An aspect that used to require trust, now would require even more trust. What Casa should have done, is to address the weakness of the mobile key head-on, instead of building more features on top of it.

IMO the design is not safe for long-term savings.

There are other inheritance solutions from people who don't embrace Efereum for the fiat profits.

*with a $250/year plan, so only paid investors.

Casa's inheritance protocol has many similarities with Nunchuk's, with some key differences.

I wrote a review / comparison here, for anyone who's interested: https://nunchuk.io/blog/casa

I think the fundamental use case, and who the users of this type of product would be, is largely missed in this discussion thread, so far.

These third-party, collaborative, multi-sig solutions, that feature Inheritance plans (like Casa, Nunchuk, Unchained, etc), are primarily for less technically-savvy Bitcoin HODLers (unlike those on Stacker News who largely understand Bitcoin).

While the primary HODLer themselves may be able to intelligently protect and access their Bitcoin, their heirs may be clueless. So instead of risking loss, these third-parties offer a way to pass on the Bitcoin via solutions that are very easy to execute by the less tech-savvy heirs.

And, they are 2-of-3 so the custody partner never relinquishes control to the third party.

While nothing is perfect, it seems these companies understand their customers want to mitigate counter-party risk, while also giving their heirs an easy way to access their Bitcoin upon their demise.

These announcements always have to explain what happens when the company goes out of business imho.

In general, I'm excited to see more inheritance options. The problem comes up a lot on here.

The idea is good but I won't do it for security issues. You can affirm, reaffirm but sharing private keys through a third party app isn't trustworthy. Supposing I die and have done Casa already, my inheritance would be delivered to my heir through CaSa is the medium. Fine what would you be asking them to bring? The death certificate? Suppose someone forges it before I die, you wouldn't grant access.

I have a diary and and everything's written in it. If I die my dear ones will have what I have.

It sounds like you haven't read about how it works. The system doesn't require the heir to verify their identity - you have already shared an encrypted form of your key with them, they just have to trigger the unlock timer to access the key they already have along with a signature from Casa's recovery key. It's basically just a timeout system that unlocks access to the key material that has already been distributed.

I have read. My concern is 'why third party?'

I have a simpler solution. Write up everything in a diary, keep it up in a safe place, write your will and enjoy.

My brain finished your sentence before I finished reading it. It had replaced enjoy with die. Not sure what this says about me~~

There's a six-month stay on the heir getting access to the key according to the article and over the course of six months they try to contact you in case you aren't dead. And - both you and the heir provide ID to set this up.

So the attacker would need to fake your heir's id, have your mobile key, a fake death certificate, wait six months, and you would have to be unreachable for six months.

(I'm not defending the solution ... not my place ... I just thought I would clarify based on the article.)

both you and the heir provide ID to set this up.

This is only for "Casa Private Clients." My bad. Otherwise I think I got it right.

Tiers! Or, may be I just didn't get it. I'm not a native English, so sometimes I may misinterpret. Sorry, if I did.

Thanks for clarifying. I still have doubts. There's no clarity over the methods, they would contact me. Suppose for some reasons, I lose contact, may be I'm hospitalized with comma, or may be I am in the jail. Will they verify physically? Or else, Will they verify the tomb, if a person dies?

And if someone really fakes up everything and they allow that person to take the inheritance keys, he becomes the owner. Noe the person that was faked returns, will they compensate in such a theft case?

You've given the key to the heir. Casa doesn't have access to it. Your heir receives it through scanning a QR code from your phone.

All of this needs to be viewed in context of the alternative. If you're in a comma, have a single sig wallet, and your heir has access to it, you're worse off than this solution afaict.

Correct, I just don't like 'third party' entering in the whole narrative of passing Bitcoin wealth to the next generation. I think everyone should be aware that death is something that can come anyday. You just have to make sure that what you have must not go to waste. Yes, you're right that's an alternative, personally I don't view it as a good and reliable option.

Depending on your situation, having a non-unilateral acting third party, who will likely make a disjoint set of mistakes from the mistakes you would make handling key material, is a feature.

Okay sir, let me give it another try. May be I am missing out on a few points. If Casa is safe and sound and remains that way for a period of time, I and I think most other conservatives like me would definitely establish faith in the solution. Thank you for your valuable inputs.
