Proof-of-time

Proof-of-time (PoT) is a blockchain consensus mechanism based on selecting validators in proportion to their ranking scores and a fixed stake. The algorithm gives each validator a score based on its historical experience and other validators’ experience with the node.
Proof-of-time (PoT) is a consensus protocol that uses a “self-selection voting mechanism” based on a verifiable delay function (VDF) to choose validators and focuses on how long the validator has been accurate and active within the network. The PoT mechanism is performed in two stages, namely soft and hard voting.
