Proof of Storage-time (PoSt) is a cryptographic primitive
that enables a server to demonstrate non-interactive continuous avail-
ability of outsourced data in a publicly verifiable way. This notion was
first introduced by Filecoin to secure their Blockchain-based decentral-
ized storage marketplace, using expensive SNARKs to compact proofs.
Recent work [2] employs the notion of trapdoor delay function to address
the problem of …
