Does mirroring deal with this? Somebody downloads the database and hosts it somewhere else, a bit like TPB or Sci-hub. I suggested this in my original post. Which host gets "elevated" to be the official source of truth is decided by community concensus.

Then you run into the problem of deciding who is running the authoritative mirror when the existing one goes down. If there's no single authoritative mirror then you could potentially double-spend your money by spending it in different places on different mirrors.

Mirroring doesn't deal with this because there's always a single target, elimination of which disrupts the whole system, since some time will pass until yet another person puts a target on his back, and there is the problem of finding out which one is legitimate in case if there are few successors.
