What Are the Key Differences between Decred’s Hybrid Model and the Original Proof-of-Activity Concept?

Decred's hybrid model is similar to Proof-of-Activity but with some key differences. In Decred, PoW miners create new blocks, but it is the PoS stakers who vote to approve them.

This gives the stakers more direct control over the governance of the network. In the original PoA concept, the role of the stakers is more limited to signing and validating the blocks that have already been mined.

Decred's model is often seen as a more advanced and decentralized form of PoA, as it gives the community more power to shape the future of the project.
