I reported a double-spending bug in Cashu, and they asked me not to disclose it for one year.
Floppy found a DoS vector, received a grant for it, and gave them how much time? Two weeks? Not happy with that, they threatened to attack the mints. What attracts these kind of psycos to the FOSS circles?

By the way, the document that explained how you would own nothing and rent everything from the owners of everything has disappeared.
Does anyone have it?

Two weeks ago I attended the presentation of SatoshiLab's latest hardware wallet, the Trezor Safe 7, and I will be sharing random thoughts. Here the first one:
SLIP39 (Shamir Secret Sharing or multishare backup).
In 2013, Trezor founders pushed the first draft for what became known as BIP39, a way to encode binary data in a human-readable format as a simple list of words. For context, at that time HD wallets didn't exist yet—or at least I don't recall any—and backing up your Bitcoin wallet meant simply making copies of your wallet files. While BIP39 is just an encoding mechanism that could theoretically encode any binary data, in practice it's used to encode the master seed for hierarchical deterministic wallets.
The first hardware wallets had only two buttons and very limited displays, so they needed a user-friendly mechanism to allow users to back up their seeds. BIP39 was perfect for this, and I believe—though I could be wrong—that this was the main goal of the BIP. Regardless, BIP39 was massively adopted, and currently every wallet I know of uses it, whether software or hardware.
As a wallet developer, I know that backing up wallets is perhaps the first and most important thing to implement, and also one of the most difficult, because there's no standard for saving metadata. The only thing that really works and is interoperable is BIP39.
Now SatoshiLabs has decided to make SLIP39 the default backup mechanism for the Trezor Safe 7, which surprised me. While I believe this is the right decision and SLIP39 is more flexible and generally superior, moving away from the most widely-used backup technology in the entire crypto space requires a level of courage that's somewhat unusual.
Disclaimer: I implemented SLIP39 in Wasabi Wallet with financial assistance from SatoshiLabs via a grant. While I would have implemented it regardless because it's been on my wish list for years, the grant certainly made it easier. I'll be making Wasabi use SLIP39 by default soon as well.

The IA-generated Michael Saylor conference talks are taking scams to a new high level.
Saint Thomas Aquinas, 800 years ago:

f "any" peace is better than any war, why does nobody accept being invaded, robbed, or humiliated when the alternative—war—could be worse? Why do humans consistently opt for the worse option then? It seems that everybody knows that war is the worst thing ever and peace is the best thing ever, and yet peace is always interrupted by war. But why? Because the premise is not true. Many wars are preferable to many forms of peace, because some peace arrangements are unacceptable and some wars are simply too tempting.

How perverse must the ideas of CBDCs and digital IDs be that not even the ideologues behind Agenda 2030 have dared to include them among their list of objectives that the devil wants to accomplish for this decade.

Pretending to be a good person is easier, and much cheaper than doing good; you just need to criticize those doing real good for not doing it well enough.
Here we go again, that's why Wasabi tries to minimize the number of dependencies to three: NBitcoin, Avalonia, and NNostr (from a reputable dev, but I will remove it anyway).
However, every time someone requests a feature, the conversation goes like this: "Why don't you use LDK, NDK, _DK? There are already bindings for .NET!" Look, you shouldn't even trust your own team, much less a team of unknown people. And yes, it sounds crazy and makes all features to come late but safesty is THE feature for a Bitcoin Wallet.

Imagine you want to know the distance of each of your coins from the nearest coinjoin transaction.


Wasabi coordinators will be published as onion services automatically by default in the next version. Wasabi coordinators' operators won't need to even install Tor.
Additionally, Wasabi coordinators will be able to run not only with heavily pruned nodes but also with nodes running in BlocksOnly mode, which uses less bandwidth and CPU at the expense of not having fee estimations.

This works better than what you would expect, but not always.
Two good friends of mine asked for my advice about how to bring their salary into the country without having to go through the forced selling imposed by the central bank, and I convinced them to ask their employers to pay them in bitcoins. Both complained that by doing that they would be seen as problematic or unreasonable, but I insisted and told them that if their employers do not want to pay them in what they want to be paid, then they were not valued by their employers. They have been paid in bitcoin since then.
A few months after that, an old employer of mine requested me to help them with a very serious problem they had with their biggest customer, and I accepted only if they would pay me in bitcoin. They accepted the condition and I solved their problem that same day, but then they refused to pay me in bitcoin, arguing that it was difficult and that their accountant was not happy and so on. I also refused to accept pesos and that was all. Now they cannot call me never again, what is okay.
Very interesting. @nopara73 had an account in Coinbase which he hadn't used in more than ten years. Then, suddenly he received an email saying that he had been deplatformed because his account had engaged in prohibited uses.

As you should all already know, exchanges spy on you not only before depositing but also, and even more importantly, after you withdraw from them. That means that if you did something that they don't like, like coinjoining a UTXO that they know was yours, they will close your account.


When I was a kid, even many years after the Argentinian civil war, it was still pretty common to assume that your phone calls could be intercepted. That sentiment changed during the nineties, and I forgot the old days, but it wasn't until during a talk with a prominent local laywer I mentioned something that made him hang up the call immediately. Then I undertood, we don't undertand how important privacy really is, but people in power do.
In Argentina, it was prohibited to buy, sell, or exchange foreign currency. Whenever the "blue dollar" (the free/black market exchange rate) surged significantly, the government dispatched police to apprehend currency exchangers and intimidate potential participants.
I struggle to see how this same pattern won't eventually replicate on a global scale. We may soon witness the emergence of a "bitcoin blue" rate that substantially diverges from the prices listed on regulated exchanges.
As I have observed in my country, the incentive to arbitrage are an overwhelmingly powerful. Purchasing restricted, undervalued bitcoins and reselling them in unregulated markets at repetition is something that no government intervention can stop.
