OpenSats betreffend ist die Sache denke ich mit dem Rücktritt von NVK aus dem Board geklärt — dort gibt es ggf. auf das generellere Verhalten von NVK bezogen Learnings zu ziehen, jedoch weniger was die ColdCard-Sache betrifft.
Matt & Marty sind denke ich eher ihrem Gewissen verpflichtet als (vom Ten31-Investment abgesehen) konkret direkt involviert — ich denke dort ist es vor allem die Scham darüber, sich dermaßen getäuscht zu haben bzw. geblendet worden zu sein. Klar, ein Restzweifel bleibt mit den offenen Fragen (siehe meine andere Antwort) immer, dennoch nehme ich ihnen ihr Statement in der RHR Emergency Folge dazu ab und kann mir vorstellen, wie übel und schamvoll das vor allem für Matt ist.
Ich fand die ColdCard als Produkt auch super und habe sie empfohlen, obwohl ich NVK menschlich für sehr fragwürdig gehalten habe — im Nachhinein machen diese Red Flags alle Sinn, daraus gilt es imho aber eher persönlich zu lernen, als anderen Leuten im Space Vorwürfe zu machen.

Was die ganzen Geschehnisse um den CoinKite CTO angeht (siehe Ref ganz unten) gebe ich dir recht, dass es erst einmal wahrscheinlicher scheint, dass es ein Inside Job gewesen sein könnte. Ob es tatsächlich so war oder nicht wird sicher vor Gericht erörtert und versucht geklärt zu werden. Auch wenn es augenscheinlich gut so abgelaufen seien könnte, wie man es sich ausmalt, kann ich es mir dennoch auch mit etwas mehr Abstand immer noch nicht ganz vorstellen und für mich ergeben vor allem die hier genannten Kontrapunkte da keinen Sinn ...

Yes. My main goal was getting him excited about the possibilities and sparking the interest and creativity to create stuff, instead of sitting in front of YouTube or the PlayStation.

I collected 200g of egg shell, which is around 40 eggs I'd say. You can do as many as you like, the ratio is ~1:10 with vinegar in terms of weight. So in my case I used roughly 2 liters of vinegar. Let it sit for 7 days, strain and bottle it afterwards. These two liters will last forever as it should get highly deluted at about 1:1000.

I'd understand the disappointment and anger on his side, yet I think simply leaving without at least clarifying some more things wouldn't be good. I don't have a problem with them recommending or even shilling the Coldcard, but with the investment relationship and unanswered questions like the potential knowledge about vulnerabilities, I think the case deserves further explanation on Matt's and Marty's end.

Appreciate the honest words and reflections on this. This is a total desaster and the arrogance and negligance that led up to it are unrivaled. The space has a lot to learn from this. Onwards.

2026-08-04 13:04:02 CEST

Crazy indeed, but tbh the circulating theory of an inside job doesn't really make sense to me and seems overblown. I dunno, but...
They'd have accepted the risk for this to come up via external review and vulnerability reports before they could harvest a substantial amount. This would have destroyed the companies reputation similar to what we see now. There's also a the risk for an attacker to grab the funds before they get to collect them. Both scenarios seem way more likely then CoinKite or an employee sitting and waiting for five years — especially as there where multiple reports of individual incidents over these years, each asking for further investigation.
I totally get why people are upset and wouldn't rule this out entirely, yet it seems far more unlikely to me. The more likely scenario imho is that they were too arrogant to look into the reports, giving the attacker the time to proceed slow and steady. Then, last week the attacker might have lost exclusivity on the insight and someone else joined the drain, forcing one of the hackers to go full blown.

Dringende Info für die ColdCard-Nutzer unter euch: Alle Seeds die mit den Firmwares ab Anfang 2021 generiert wurden, nutzen nicht genügend Entropie und können recht einfach geknackt werden. Sofern ihr eine Passphrase nutzt ist das kurzfristig gut, aber auch hier ist dringend das Migrieren auf einen neuen Seed (im Idealfall mit eigener Entropie per Würfeln) geraten.
So wie es aussieht, sind Seeds die mit vorherigen Versionen der ColdCard generiert wurden sicher. Dennoch solltet ihr euch generell auch da Gedanken bzgl. Nutzung von Passphrases oder MultiSig Gedanken machen — ich gehe davon aus, dass das nicht der letzte solcher Fälle bleiben wird.
https://blog.coinkite.com/coldcard-mk3-seed-generation-warning/

2026-07-31 15:46:27 CEST

One should also note, that only seeds generated after their license change (end 2020) seem to be affected. The first version after the code changes causing this shipped March 1st 2021 — so seeds generated prior should be safe for now, at least in theory.
Nevertheless, moving to a new, more secure setup with self-rolled dive entropy and passphrase seem to be a no-brainer now. Evaluate multi-vendor multisig as an option as well.

Super, das scheint auch ein richtig guter Spot zu sein: überdacht, sonnig, warm.

Closing in on my monthly OpenCode Go limits I started using cheaper models to see what they are good for: As longs as used with a narrow scope (e.g. per feature or improving test coverage) cost-efficient models like DeepSeek v4 Flash get the job done, though they might require one or two additional iteration steps.
At least for the stuff I'm building I'd say one doesn't have to spent lots of money for inference to get good results. Also I noticed how prompting efficiently forced me to become a better product steward, thinking through features in terms of goals rather than implementation details.
