Signum White Papers
Signum White Paper, Incorporating the Best From Several Predecessors

With the fork from NxT, Signum removed proof-of-stake and replaced it with proof-of-capacity. A concept similar to proof-of-capacity is referred to as proof-of-space (no active coins). The proof of space white paper is referenced below. Based on this paper, a proof-of-space cryptocurrency called SpaceMint was proposed. It is included here as a loose reference as it specifically references Signum.
