Enjoyed the PoR video, but just wondering if anyone can point me in the direction of any more detailed (but preferably reasonably accessible!) info on how it works.
As a related point, what level of security does PoR provide? Is it testing something absolute, or does it always depend on consensus?
At the risk of deviating too far for one thread, how do PoR, consensus by PARSEC and any other security mechanisms such as sharding combine to protect against attack?
To explain at least partly why I ask these questions, I’ve been following a couple of recent threads mostly focusing on the maths behind an attack on consensus, and although in isolation this maths maybe looks a little gloomy, it seems clear that other mechanisms are providing the primary protection from a purposeful attack such as stealing/printing Safecoin, or stealing data.
I may be on completely the wrong track but the attack that haunts me is a long term Sybil one by a large company, government or terrorist organisation that is willing to pay the price purely in order to destroy the network, by controlling a large number of vaults and then at a given moment simultaneously starting to lose data, or return scrambled data (on their own terms of consensus, in the random sections they happen to control at that moment.) Given what we are all hoping is at stake, the loss of even one piece of data in this way could surely be fatal for the network.
