Abstract
In conventional Proof of Stake (PoS), the nodes with higher stake would have a higher probability of being selected for the block rewards. Block rewards are constant regardless of the node reputation. In Secure Proof of Stake (SPoS), the nodes with higher reputation have a higher probability of being selected for the rewards. The main concept in Hybrid Secure Proof of Stake (HSPoS) is to separate the block consensus from the block rewards. HSPoS proposes that the rewards become a function in the reputation of the node. Thus, while the node probability of being selected is based on the fungible stake, the rewards for the block is adjusted by the non-fungible reputation multiplier which is a function of the node’s reputation. HSPoS enables a transitioning process in which traditional PoS consensus algorithms, can be used and maintained while being supplemented with SPoS characteristics and node reputation. This enables enhanced experimentation and allows a slow transitioning from PoS to SPoS
