We are now mapping the ongoing Coldcard attack with a live dashboard - link below
I am deploying tripwire UTXOs that have varying levels of added entropy on top of the broken default seeds. We have different levels for 5, 10, 15, ... dice rolls, and 1, 2, 3, ... passphrase words.
This is so we can approximate the frontier of the confiscations that are actively happening.
The control UTXO with no added entropy was swept in an hour.
I took real measurements on an MK3 to calibrate a "good bad entropy" emulator in software. The control confiscation has proven it to work.
I am going to continue to deploy tripwire UTXOs along the bit curve.
Huge thanks to @Rob1Ham @otaliptus @PortlandHODL and other redteamers for the help.
I make this jab not because I'm some shithot carpenter - I'm not - but because you need to keep in mind that for engineers, the physical world is the ultimate benchmark.
You are a second-class citizen in the world of doing things until you have reckoned with building something in the physical world. It is ground truth. The software wants us to forget that, and spend our lives staring at flashing lights.

I know I'll catch heat for this, but since when do I care.
These are White boys. They'd be at home in any town in Oklahoma if they could speak the language.
They aren't our enemy. Killing them would be as stupid and self-destructive as killing Germans was in 1943.
The world needs White men and women.
Or there is no bright future.

🚨 TRIPWIRE SWEPT — 5 dice rolls of added entropy
A deliberately-weak Coldcard researcher honeypot has been emptied. The rung that fell is a live measurement of how far the operator's key grinding reaches. (See cktripwire.com @jamesob)
Added entropy: 12.9 bits (track dice, rung 5, id )
Amount: 0.00044567 BTC

When all is said and done, what did you sacrifice to live virtuously?
The only concrete proof of your realized virtue will be what you gave up, what comfort you deferred.
It's easy to be virtuous when virtue is costless. In my own case, I haven't sacrificed very much so far.
Becoming a software engineer and eventually working on Bitcoin Core was an easy path. To begin with, being a programmer in the 2010s paid well, was comfortable, interesting. The barriers to working on bitcoin were very low. At no point did I really have to *give anything up*, aside from stomaching a little bit of uncertainty.
Working on bitcoin is fundamentally an easy, financially rewarding path. I have to laugh a little bit anytime I hear people being glazed for "how much they gave up" to work on bitcoin. "Thank you for your service." Thank you for what, getting paid well to listen to techno in a climate controlled room while typing?
You know what requires sacrifice? The social costs associated with refusing to ignore overwhelming evidence and calling out organized Jewish power in America, which is ripping the country to shreds. The ethno-supremacist power that underlies entities like Soros, neoconservatives, Epstein, AIPAC, and Hart-Cellar.
Sacrifice: for example, the social costs associated with openly acknowledging that different races have different average characteristics, actually. That diversity in most instances is a weakness, and not a strength. That maybe a population with 12x the murder rate of the native population shouldn't be propped up with feel-good DEI policies and a welfare state that subsidizes the creation of fatherless children at the expense of white family formation.
You know what requires sacrifice? Prioritizing the confrontation of these problems in a humane, Christian way over the simple pursuit of making more money in an ethically bankrupt system.
May God help both you and me pursue sacrifice for the sake of loving virtue.

Have said it before and I'll say it again: supply chain attacks are going to be a theme of the 2020s

Rust people, genuine question: you're not worried about supply-chain attacks via the npm-style proliferation of small packages because... <comments below?>
There aren't stdlibs for doing decent CLI parsing, cryptographic hashing, JSON parsing, ...
If Lloyd got got, any of us could get got
Rust blows: npm with lipstick. Don't use it, or VM it if you have to.
My laptop was compromised through the rust supply chain attack thing (blake3 dependency). I'm revoking everything. Github tokens and crates.io is done and nothing malicious has been released.
