Proof-of-Replication (PoRep) State reliable Theory Audit wip Edit this section section-algorithms.pos.porep In order to register a sector with the Filecoin network, the sector has to be sealed. Sealing is a computation-heavy process that produces a unique representation of the data in the form of a proof, called Proof-of-Replication or PoRep. The PoRep proof ties together: i) the data itself, ii) the miner actor that performs the sealing and iii) the time when the specific data has been sealed by the specific miner.
