This thing is about trust, and personally I'd prefer signing the 
derivation->output hash pairs and having some web-of-trust-like 
solution. (Although some build redundancy is certainly good, for 
multiple reasons.)

The problem with seti at home -like solutions is that verifying correctness 
is generally no cheaper than full rebuild. Therefore, the untrusted 
computers bring very little added value. (They can distribute the 
content signed by trusted people, but distribution isn't much of a 
problem in our case, IMHO.)

I'm not sure about such schemes either. It isn't very economical to 
build everything 1000-times. I do see the bitcoin-like inspiration (I 
guess), but I wouldn't apply it here, at least not in this way.
(Do we want to give most decision power to those who make most claims on 
the build results? Even if we extend them with some additional
