"#Bitcoin is opt out technology. So you don't have to persuade people. You can just unilaterally use better money, hard money."

Why the SEC pivot?

Because banks get crushed being forced to buy negative real yielding bonds. Selling #Bitcoin  and now “Crypto” ETFs help them to monetize insane debt levels and inflation.

Banks call the shots, not government.

In the end, there is #Bitcoin  and everything else

New police technology able to detect phones, pet trackers, and library books inside a moving car

I'm not going to rewrite this my own words. Hear it from Globe Echo quoted, because sometimes the truth is scarier in a more neutral tone:

Quote:

"American police are testing a new technology developed by Leonardo, an Italian surveillance and defense company, that can scan moving vehicles for signals emitted by devices such as phones, smartwatches, pet chips, library books, and more. The technology, called Elsag EOC Plus, can identify specific models of devices and create a unique “fingerprint” linked to a car’s license plate number. This data can be used to track individuals as they move through areas with license plate scanners, raising concerns about potential privacy violations.

According to Leonardo, the new technology can be useful not only for police departments on public roads but also in off-road areas such as rail stations and shopping centers. The company claims to have over 4,000 customers for its Elsag license plate readers in the U.S. and is actively trying to sell the new product worldwide. However, some experts, such as Matthew Guariglia from the Electronic Frontier Foundation, question the necessity and potential misuse of the technology, especially in terms of tracking and seizing electronic devices from individuals without proper authorization."

I wrote a very basic overview of watermarking, fingerprinting, timing analysis and supernodes for Bitcoin Magazine's last print issue, which is pretty much an unsolicited advertisement for why I think we need a second mempool (and also mixnets, but thats a longer story). Since no one cares about stuff like this on Twitter anyway, I'll explain here.

Bitcoin has a privacy issue on baselayer. I know this. You know this. Everybody knows this. The problem is that there's a lot of stuff we can't do to solve this issue without completely fucking up how Bitcoin works, like, say, anonymous amounts. But there is some stuff we *can* do to increase privacy on the Bitcoin baselayer. One of those things is incorporating a second mempool to integrate Dandelion++, the routing protocol used in Monero. Hear me out.

One of the ways blockchain surveillance firms identify who what transactions belong to on the Bitcoin blockchain is by operating so-called supernodes. A supernode sets up as many connections to other nodes as it can, and by doing so can establish where a transaction was first seen in the peer-to-peer network, ergo ascribe whom a transaction belongs to.

Here's where Dandelion++ comes in. Instead of propagating transactions to *all* connected peers, Dandelion++ propagates transactions like, well, a Dandelion.

In Dandelion++ propagation, Bitcoin nodes send transactions to *one* peer, instead of to all of them. This peer sends it to another peer, they send it to another peer, and so on and so forth. This is called the "stem phase".

When we've established enough plausible deniability, Dandelion++ reaches the "fluff phase". At this point, a node that did not *create* the transaction, but is simply relaying it, propagates it to all nodes in the network it is connected to, including supernodes, and the next node does the same, and so on and so forth – business as usual.

Incorporating Dandelion++ (or any other anonymizing propagation protocol, like Dandelion, Dandelion Lite, or Clover) would arguably seriously fuck up the blockchain surveillance stick as we are taking away the most obvious attack vector for blockchain surveillance firms. It's also not a trivial task, see ajtowns' overview of stempools (and no one wants to maintain another mempool on bitcoin, if we're honest). But it's a really interesting proposal to think about to increase privacy on Bitcoin that, yes, would be a lot of work to implement and maintain, but also does not get talked about enough imo for everyone yapping about Bitcoin baselayer privacy.
