Proof of Participation (PoP)

The Proof of Participation consensus equally distributes decision power and rewards amongst every node in the federation that contributes to a blockchain’s operation. The protocol only lets new people into the federation slowly (and prioritizes those willing to stake the most). It measures the “participation” of nodes by whether they are rebroadcasting transactions and blocks, and kicks out the nodes that aren’t doing their job.
