Like Proof of Authority, Proof of Participation takes advantage of a federated consensus algorithm. However, unlike Proof of Authority, the process of joining the federation is fully decentralized, permissionless, and fair.
Proof of Participation takes the best part of proof of stake and takes a step further by reducing dependence on the token’s value for security as explained in this infographic.
ZooBC’s Proof of Participation consensus was designed to overcome problems in other consensus algorithms like Proof of Work. Check out some of their differences in this infographic.
