24 words don’t guarantee 256-bit security.

That statement sounded impossible... until today.

The real question isn’t:

“Do I have 24 words?”

The real question is:

“Where did those 24 words come from?”

In our latest article, we explain what happened, why it matters, and how verifiable physical entropy fundamentally changes the trust model.
