encryption – How are passwords stored in the database of a decentralized peer to peer system?

I want to use username and password instead of public key cryptography for a decentralized peer-to-peer application, but since the passwords are stored on users’ computers, there is a possibility of being stolen. How do I store the passwords securely?

And how do I give permission safely? How can I prevent someone else from gaining permission unfairly?

decentralization – What exactly stops there from being a “Bitcoin interest” platform that’s decentralized?

I know about centralized services like “BlockFI”, which demands that you do the KYL/AML crap to get any money. But what if they paid you in Bitcoin or something instead? And it was entirely decentralized? What’s stopping this:

  1. I download some sort of trusted desktop application which is open source and lots of smart people recommend.
  2. Inside, I send in 0.1 BTC into this thing, which is then “smart-contracted” in some complex manner so that it will be returned to me after a year or a month or whatever time period specified.
  3. As long as my coin is locked up in the system, I get like $1,000 USD in Bitcoin sent to me as interest per month.

No registration. No KYC/AML. No proving anything. No fiat involved. Just a pure interest.

The idea being, of course, that somebody is using that coin somehow, again according to the “smart contract” rules, in such a manner that it is safe for this system to pay me. I’m foggy on the details of how exactly this would work, but since I already use Bisq and not one single person has tried to scam me so far, after using it for years, it seems like it could very well work. That it should already exist, in fact.

So why doesn’t it?

PS: Please don’t tell me that it exists, because it doesn’t. I’ve spent countless hours going through long lists of alleged “defi” websites, and they are just link mazes/gibberish without anything concrete.

decentralization – Why is every so-called “defi” platform not decentralized at all?

Top Bitcoin and Crypto Lending Platforms, Rated and Reviewed

I’ve looked through every single one of those alleged “defi” services. 100% of them have a “register account” link which asks for usernames, e-mail addresses, personal information, etc. That is the opposite of decentralization.

None of them actually allow me to use them. I’m baffled as to who exactly is using these things and how they can be seen as “decentralized” in any manner.

Do words no longer have any kind of meaning?

email – Is there some decentralized message system in actual use which I can offer as an alternative to entering an e-mail address?

I’m trying to be nice to my customers. I want them to be able to use my service without having to enter an e-mail address. However, I’ve been hunting myself for ages for any kind of “e-mail replacement” yet never found one. So I have no idea what I could reasonably let them enter as an alternative to having to enter an e-mail address, which I can then reliably use to send them notifications, such as:

Your submission has been approved!

Or:

Your ticket has a new reply: blablabla…

It should be something which doesn’t require me to have registered an account somewhere. I’m imagining that they open up some kind of application similar to Bitcoin Core, but instead of “Generate new receive address”, they “Generate new communication address” and then enter that unique string into my form instead of an e-mail address, so that I can reach them (for as long as they want to keep the address) without using e-mail.

I tried to understand how to implement the “browser notifications” thing a few years ago, several times, but found it to be incomprehensible and centralized. Did anything ever come from that? I just remember it as very annoying when sites kept asking for permission to send those things.

Is there such a thing yet? Which is worth supporting at all? I kind of gave up on “Bitmessage” long ago…

decentralization – Is there such a thing as a decentralized stock market desktop application, in concept similar to Bisq?

Please note that I’ve already visited thousands upon thousands of slick websites with fuzzy claims about being “the future of money” and I consider them all to be vaporware at best, and usually downright scams. I have no use for yet another such URL where all I get is the same nonsensical word salad but nothing that can actually be downloaded and used today, right now.

Is there such a thing as a currently launched, in-use, decentralized trading desktop application? That is, not a centralized website with “Register” and “Log in” on it, not “Open in App Store”, not “Available for your Android phone”, but an actual program that is downloaded, installed, run, and which then functions like Bisq, but instead, you can trade on stocks with zero KYC/AML BS, zero registration of any accounts, zero any BS except that you have to back up a file on your computer. Like I already do with Bitcoin Core and Bisq. But for trading stocks and perhaps other financial instruments, in a tokenized digital form which has nothing to do with the “traditional” stock market.

My guess/hunch is that this “is being worked on”, but is not actually available yet.

Just like in Bisq, I would expect it to require me to initially send in some satoshis to my “wallet” inside of the application, which is then locked while used as some kind of internal tokens until I withdraw the BTC back to my own wallet. (If I have any left after making actual trades.)

As you might have guessed, I’ve extensively searched for this myself before asking here, and only found the kind of “word salad” fake websites which offer nothing but empty claims of being “the future”.

decentralized exchanges – What exactly is the relation between Bisq and Bitcoin Core?

What exactly is the relation between between Bisq and Bitcoin Core? It seems like Bisq can function perfectly well without Bitcoin Core, but if you do run Bitcoin Core at the same time, it appears to have issues (sometimes) with syncing the Bitcoin network. (Whatever that means in terms of Bisq, since it’s clearly not a fullnode Bitcoin wallet.)

I’ve tried to figure, read and ask my away to the answer to this question for a long time now, but I’ve just been ignored.

In what technical/concrete ways does Bisq use/depend on Bitcoin Core, other than allowing you to easily click a button inside of Bisq to open up Bitcoin Core with the fields pre-filled in?

If it works without Bitcoin Core installed, is there some benefit in allowing Bisq to “utilize” Bitcoin Core?
