The Proof-of-Staked-Authority (PoSA) consensus algorithm is a hybrid between the Proof-of-Staking and Proof-of-Authority consensus mechanism.
Nominated proof of stake, or NPoS, is similar to proof of stake (PoS) in allowing users to earn rewards for validating new blocks, but it differs in that only nominated nodes are allowed to participate in block validation.
Can someone please elaborate on the difference/s between PoSA(Proof of Stake Authority) and NPoS(Nominated Proof of Stake Authority)?
