PoET brings low computation with justification, designed by intel via leveraging SGX, a trusted computing policy. In this algorithm, each node waits for the threshold period; here, the node which finishes the threshold time is allowed to generate a new block. The PoET consensus is required to guarantee two key features: First, the joining nodes legitimately decide on a time that is sure arbitrary plus not a shorter interval. Second, the frontrunner concluded the waiting time. However, the issue is SGX is not a reliable, trusted computing skill. Two features proposed to overcome this issue: varying the probability distribution and executing statistical analysis to refuse a few blocks engender by a specific portion of nodes.
