The main participants in the Decred community include the stakeholders, PoW miners, and community contributors. Splitting the power of consensus validators (i.e., miners and stakers) into two groups is designed to mitigate the ability of small subsets of people to launch chain reorganizations, and also plays a critical role in governance and funding.
For example, block rewards are split between the miners, stakeholders, and Decred Treasury as follows:
PoW Miners: 60%
PoS Voters: 30%
Decred Treasury: 10%
The Decred Treasury funds the development of the Decred network through a community-driven voting mechanism called the Politeia voting and proposals system, which is part of the overarching governance structure.
