What Does Proof of Stake (PoS) Mean?
Proof of stake (PoS) is a method for cryptocurrency verification through distributed consensus. In a proof of stake system, stakeholders are chosen as creators of a block through analyzing criteria combined with randomization.
Techopedia Explains Proof of Stake (PoS)
The general idea of proof of stake is meant to provide an algorithm that equalizes probability for figuring out a selection process for block creators. Some additional elements include delegated proof of stake protocols that use various nodes, and randomized proof of stake which, again, uses the principle of randomization.
