Publicly Verifiable Proofs of Space
Markus Jakobsson
Abstract
Abstract—We introduce a simple and practical Proof of Space (PoS) with applicability to ledger-based payment schemes. It has a dramatically simpler structure than previous proposals, and with that, becomes very easy to analyze. A proof can be as short as a few hundred bits, and can be publicly verified using only two hash function computations.
