# kaal:claim:3125827-004

**Claim.** Because all block creation fees are shared with the whole group as a reputation weighted salary, SPoS removes the direct monetary reward for forming mining pools or block production cartels, which the authors identify as a decentralization threat that raises the likelihood of 51% attacks.

**Type.** mechanism  **Support.** argued

**Holds when.**

- fees distributed as a reputation weighted salary rather than paid to the producer

**Source quote.**

> Therefore, unlike every other implemented platform, there is no direct monetary reward incentive for creating mining pools or block production cartels, which are a threat to decentralization which increases the likelihood of 51% attacks.
