Basically required if you run Windows.

But I've been Linux only for 20+ years and done just fine without antivirus software.

OS X, you're probably fine without it as long as you're not visiting shadier parts of the internet.

Because people have security needs beyond Bitcoin.

Over the long run we expect cryptographic keys to become important in a variety of aspects of our lives, not just finance / assets.

Casa is designed so that we're not a single point of failure. The first thing that happens after you initialize a vault is you receive your instructions for how to recover funds without use of Casa software or infrastructure. https://blog.casa.io/how-casas-sovereign-recovery-works/

Of all the dynamic block sizes algorithms I've looked at, I like Monero's the best. I think some of its ideas could be worth incorporating. In particular, the economic aspect that larger blocks also requires higher transaction fees - any block size proposal should take long term thermodynamic sustainability into account.

First I've heard of el-tor, will definitely have to investigate.

My initial concerns would that high bandwidth" makes me worry that it may be more centralized or susceptible to timing attacks.

Given that it's such a new project, will want to see a lot of eyes on it before anyone considers it secure.

At a high level I do like the idea of incentivizing people financially to help improve privacy. Hopefully the characteristics of the network aren't limited by the level of Lightning adoption.

With a password manager? Nothing fancy. I have a ton of different phone numbers, email addresses, physical mailboxes, etc. Each identity has its own encrypted note with all of the relevant contact details.

I think it will mostly come down to the team and level of service. Any software we write can be copied; for example we were the first to build key rotation functionality and created the concept of health checks. Several others have since followed suit.

That's tough. I've had the privilege of working with so many incredibly smart people.

I also run the Mensa Bitcoin Interest group which technically has a lot of smart people, though in my experience high IQ tends to come with trade-offs like low EQ.

Pieter Wuille and Olaoluwa Osuntokun are near the top of the list.

We make it very easy to put yourself into a highly robust security model that eliminates single points of failure.

The best way to dig into the details is to read through our threat model at https://docs.casa.io/wealth-security-protocol

20 years ago I let a friend hold one of my handguns and I had removed the magazine but failed to clear the chambered round. He immediately aimed it at a wall and pulled the trigger, resulting in a negligent discharge. I was deathly afraid for a few minutes that he might have shot someone on the other side of the wall. Thankfully no one was hurt!

We recognize that some people disagree with this perspective and are willing to cede that market segment to Bitcoin-only competitors.

I suspect a lot of folks aren't aware of my BitGo history where I went through the same process of transitioning the company from Bitcoin only to multi-asset. I wrote about some of my issues doing so at length, and I still stand by my position that Bitcoin is better designed. https://blog.lopp.net/the-challenges-of-building-ethereum-infrastructure/

But at the end of the day we're running a business, not a church.

The Sovereign Individual for sure

No KYC at Casa, so that's a big distinction between us and Unchained & Swan.

Biggest differences between Casa and Nunchuk & Keeper is that we A) support other assets and B) have higher levels of consultation that expand beyond just the key management / asset security.

I almost always order my steak rare.

Restaurants almost always overcook it.

Personally I'm a big fan of reverse searing cowboy steaks so that I can get them the perfect temperature all the way through. Extra points for dry brining a few days beforehand.

Yeah it's a pretty simple trade-off: with ecash you get really strong privacy at the expense of rug pull risk. Fediment seeks to reduce that rug pull risk by distributing it, but it will always come down to the reputation of the federation members.

I'd go with CTV in order to get covenants. I wrote about covenants several years ago:

Well all the more reason to use a dedicated key management hardware - they are safe to use even if your laptop is compromised.

To keep your devices clean:

yep, sufficiently large numbers are very difficult to grasp.

Perhaps all civilizations fail to advance past the point at which they're capable of destroying themselves... without destroying themselves.

I think block size / weight shouldn't be "pick a number" political games every so often, but rather should be thought of similar to the difficulty target adjustment, but with economic factors. I'm hopeful that an algorithm can be developed that takes everyone's concerns and incentives into account.

To be clear we did open source the code and I think Umbrel used some of the dashboards in their first version. https://blog.casa.io/open-sourcing-the-casa-node/

With inheritance you're trying to balance very different sets of security. On one hand you probably want to be the only one controlling funds while you're alive, but if you die you want a switch to magically flip so that some other set of people can access the funds.

This is where multisig really shines in my opinion. You can distribute keys in such a way that executors don't have control of your funds, but can collaborate to recover funds in the event of your passing. We developed a pretty nifty user friendly inheritance solution at Casa that only takes a few minutes to onboard executors. The neat thing is that it doesn't rely upon the legal system. https://casa.io/inheritance

With UTXOs the main thing I caution against is withdrawing to self custody too frequently. Probably shouldn't do that more than monthly or you'll regret it many years down the road.
