PoSt

Proof-of-Spacetime (PoSt) State reliable Theory Audit wip Edit this section section-algorithms.pos.post From this point onwards, miners have to prove that they continuously store the data they pledged to store. Proof-of-Spacetime (PoSt) is a procedure during which miners are given cryptographic challenges that can only be correctly answered if the miner is actually storing a copy of the sealed data. There are two types of challenges (and their corresponding mechanisms) that are realised as part of the PoSt process, namely, WinningPoSt and WindowPoSt, each of which serve a different purpose.
