Will our elite top 1% be managing, repairing, upgrading, etc. the spyware and killer robots? Won't the other 99% also be able to acquire their own counter-spyware and protection bots?
I'm just saying if bitcoin prevents most people's wealth from being covertly siphoned off, as in our current system, it will be much harder for a small minority to control them.

Re 8: how will the socialist/communist/authoritarian govs pay the enforcers of their policies if over half of capital/wealth is difficult or impossible to confiscate? If it's the rich elites footing the bill will they really be able to sustain their position in a new hard money (bitcoin) world?
My understanding of the most recent hard money era is it tended to empower the productive but also improve the standard of living and thus autonomy of even the relatively unproductive due to monetary deflation, improved capital allocation and tech innovation.

Whenever I read about this bill I think "Faustian bargain". The stable coin folks get full access to the US market and all the money and power that comes with, but lose any pretense of privacy or censorship resistance. They think they can somehow cheat the Devil, but he always gets his due (in this case complete government/bank industry capture).

What ever the number is it needs to be more.
According to this article there are around 52 million "every day" millionaires in the US worth between $1-5M. It should be trivially easy for these people to own and self custody one bitcoin (except of course the obvious 21M BTC reason).
We need more easy to use self custody wallets like Unchained, Casa, AnchorWatch, Proton, Bitkey, Liana, Sparrow, etc. Bring on all the projects with what ever models/trade-offs work to somehow put the keys in users hands.

Phoenix is the mobile wallet, but there's also a "headless" API version of the software that can run on a desktop or server. But to use phoenixd you need other software like @nprofile…fy4z Hub (https://guides.getalby.com/user-guide/alby-account-and-browser-extension/alby-hub/introduction) if you want a UI on top of it.
One issue you'll have with the phoenix mobile app and bolt12 is your phone app needs to be running to receive payments, at least I just tried to send a little payment to you above bolt12 "offer" and it didn't work because I suspect your phoenix app isn't running. But if you use phoenixd on an always on machine this wouldn't be a problem.
And, yes you can tell you have a bolt12 "offer" because it starts with `lno`.

It looks like Ocean is recommending CLN (https://ocean.xyz/docs/lightning) but as long as they use standard bolt12 I don't see why it wouldn't work with phoenix wallet or phoenixd. Looks like you just need to create the config for your bolt12 offer and sign it with an on-chain address key. But it's not clear to me which on-chain key you need to sign with.

Proton's design is to only store your keys encrypted (by your browser or app) on their servers. The same privacy model you have with ProtonMail. The BDK based wallet code also runs locally in your browser (wasm) or phone app.
The code is open source so you're welcome to see exactly how it works. Certainly a trade off of user experience vs security, but better than the closed, fully custodial systems out there.

@nprofile…e28s accusing Proton of being a honey pot is a pretty serious accusation. Do you have anything to back this up? All I've seen about the Proton team has been that they are pro-privacy, and very much opposed to explicitly anti-privacy companies like Google. https://moneyinc.com/andy-yen/
Their code is open source, if a privacy leak exists in their code and/or their published binaries and open source code don't match someone should be able expose it.

For those (like me) who don't want to sit through a long video here's the PDF:
https://web.eecs.umich.edu/~imarkov/10rules.pdf
@nprofile…pgn3 to answer your question, simple coding rules like this do sound like a good idea. Ideally the rules should be enforceable via clippy and checked automatically in CI.
For BDK's CI we already check default clippy and fmt rules, unit test coverage, rustsec audit, and building with different features combinations including no-std and using our MSRV.
If anyone knows of a version of these rules adapted for Rust let me know, I'd love to take a look. For a broader description of Rust best practices I like this book: https://www.lurklurk.org/effective-rust/
