From the limited information, it&#x27;s rather impossible to tell for sure. But considering you need 9 different admins in different countries, I&#x27;m presuming they are basically using a kind of DHT with a bit of extra brains controlling where the various bits and pieces are hashed. So, that said, I would presume it&#x27;s at least somewhat fault tolerant.<p>However, it&#x27;s Chaum we&#x27;re talking about, so we likely won&#x27;t know until the patent is filed.
