Cryptocurrencies have become tremendously popular since the creation of Bitcoin. However, its central Proof-of-Work consensus mechanism is very power hungry. As an alternative, Proof-of-Space (PoS) was introduced that uses storage instead of computations to create a consensus. However, current PoS implementations are complex and sensitive to the Nothing-at-Stake problem, and use mitigations that affect their permissionless and decentralised nature.
