We could even treat it as a deposit, refunded when you provide the corresponding proof. That (the up-front payment) would entirely prevent this whole category of attacks, as long as...

See **EDIT** above. Although my train of thought here was wrong, it is still true that choice of sector id allows grinding on the PoRep as a whole — so...

FWIW, replicaID currently includes the sectorID.

@whyrusleeping I actually agree with you and concluded the same in my edit. This doesn't apply to the risks of grinding to generate a fake Seal proof. Although this doesn't...

General lock is for use of the GPU. Priority lock is to kick lower-priority processes off the GPU. Why do we lock when no GPU being used? Great question. How...

Here are my thoughts. First, I agree with the sentiment: economical retrieval is important. Second, the specific proposal raises some alarms because it seems to undo the benefits of replication....
