# Hspos `kaal:entity:hspos` **Status.** derived This node is assembled mechanically from the 14 claims that carry the concept tag `hspos`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself. ## Every claim under this term 14 claims across 2 works, 2021 to 2025. **2021** - [3931933-002](https://wulfkaal.github.io/claims/3931933-002) [design/argued] -- The core proposal of Hybrid Secure Proof of Stake is to separate block consensus from block rewards, making the reward a function of the node's reputation rather than of stake alone. > 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. Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-003](https://wulfkaal.github.io/claims/3931933-003) [mechanism/argued] -- Under HSPoS a node's probability of being selected remains driven by its fungible stake, while the size of the block reward it receives is scaled by a non-fungible reputation multiplier derived from the node's reputation. > 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. Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-004](https://wulfkaal.github.io/claims/3931933-004) [mechanism/argued] -- Because HSPoS supplements rather than replaces the consensus layer, an existing PoS consensus algorithm can be kept in operation while reputation is introduced through the reward function, permitting a gradual rather than abrupt transition to SPoS. > 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. Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-005](https://wulfkaal.github.io/claims/3931933-005) [design/asserted] -- Moving a network from PoS to SPoS should proceed by evolving the rewards mechanism in two steps through HSPoS, rather than by switching the consensus mechanism directly. > In order to move PoS towards SPoS (Secure Proof of Stake),2 this paper suggests evolving the rewards mechanism in two steps via HSPoS (Hybride Secure Proof of Stake). Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-032](https://wulfkaal.github.io/claims/3931933-032) [mechanism/argued] -- Under HSPoS two nodes holding the same stake retain the same probability of being selected for rewards, but the node with the higher reputation receives the larger reward. > In HSPoS, two nodes with the same stake would have the same probability of being selected for the rewards. However, the node with the higher reputation would get higher rewards. Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-033](https://wulfkaal.github.io/claims/3931933-033) [mechanism/asserted] -- Nodes accumulate reputation in two ways: by being onboarded into the SDAO and performing well as node validators, and by participating regularly in SDAO governance votes. > 1. being onboarded into the SDAO and performing well as node validators, and 2. by participating regularly in the governance votes of SDAO.

Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-035](https://wulfkaal.github.io/claims/3931933-035) [mechanism/argued] -- By balancing validator stakes against reputation, HSPoS reaches an equilibrium of incentives in which validators are motivated both to succeed economically as validators and to participate actively in decentralized governance. > Through this balancing of validator SHAS stakes and reputation, HSPoS attains an equilibrium of incentives for validators to: a. attain economic success as validators, and Wulf A.

SSRN: https://ssrn.com/abstract=3931933 - [3931933-036](https://wulfkaal.github.io/claims/3931933-036) [mechanism/argued] -- HSPoS earns validator node reputation through a mechanism that is decoupled from the ordinary monetary system of incentive rewards. > HSPoS emphasizes validator node reputation, which is earned via a reputation-based mechanism that decouples the normal monetary system of incentive rewards. Wulf A. Kaal, Hybrid Secure Proof of Stake (2021). SSRN: https://ssrn.com/abstract=3931933 - [3931933-037](https://wulfkaal.github.io/claims/3931933-037) [definitional/asserted] -- Reputation in HSPoS is a form of social capital earned by participating in the network's ecosystem, independent of the participant's financial capacity. > Reputation represents a type of social capital that is earned by participating in the network's ecosystem regardless of the amount of financial capacity.
