The Coldcard hack proves reputation is not a security model

Reputation became the evidence

How did a community whose founding slogan is “don’t trust, verify” end up here? Psychology has names for it. The illusory truth effect makes repeated claims feel independently confirmed even when they trace to a single source. The halo effect converts status, confidence, and popular products into presumed technical authority. Year after year, the same assertions traveled through the same podcasts and feeds: critics were shills, researchers were terrorists, competitors were clones. Repetition did the work evidence should have done, and confidence became a substitute for proof.

The result is best described as epistemic capture: a community gradually outsourcing its judgment to a trusted authority until the authority itself becomes the evidence. BTC Sessions host Ben Perrin described the mechanism with unusual honesty in a recent livestream, admitting he gave the behavior a pass because he assumed the hubris came packaged with a superior ability to create and secure. Much of the industry made the same calculation. The crisis of confidence now rippling through self-custody is the bill coming due.

Verify everyone

The first priority for the entire industry in the aftermath of the exploit is users: circulate the migration guidance and make clear that updating firmware cannot repair a seed generated on vulnerable versions. Then the industry has behind-the-scenes work to do. Old recommendation pages, show notes, and product guides carry years of claims that were repeated rather than checked, and they deserve corrections with primary sources attached. The builders and researchers who were attacked deserve the airtime to explain their work. Bitcoin media needs to become adversarial again, applying the same scrutiny to friends, sponsors, and advertisers that it applies to strangers.
