>The probability of creating a block should not rely on any work unit data. Even if the magnitude of a user is compromised, or tampered in some way, it should not influence any transactions happening in the chain, nor should he be able to attack the block chain itself with this.

Happy to hear someone say this loud and clear. I was a little worried seeing the results of the poll. While I think it's fine to keep the idea of a PoR blockchain lodged far in the back of our heads, I don't see any possibility for its implementation in the foreseeable future, absent full decentralization of the BOINC side of things.

EDIT: I realize some people who voted "Yes" if the poll may have simply meant that we should at least explore the idea. Of course I'm fine with this. Let's be very very cautious regarding actual implementation though.
