Query: An Uncertainty- and Collusion-Proof Voting Consensus Mechanism in
  Blockchain   Though voting-based consensus algorithms in Blockchain outperform proof-based
ones in energy- and transaction-efficiency, they are prone to incur wrong
elections and bribery elections. The former originates from the uncertainties
of candidates' capability and availability; and the latter comes from the
egoism of voters and candidates. Hence, in this paper, we propose an
uncertainty- and collusion-proof voting consensus mechanism, including the
selection pressure-based voting consensus algorithm and the trustworthiness
evaluation algorithm. The first algorithm can decrease the side effects of
candidates' uncertainties, lowering wrong elections while trading off the
balance between efficiency and fairness in electing miners. The second
algorithm adopts an incentive compatible scoring rule to evaluate the
trustworthiness of voting, motivating voters to report true beliefs on
candidates by making egoism in consistent with altruism so as to avoid bribery
elections. A salient feature of our work is theoretically analyzing the
proposed voting consensus mechanism by the large deviation theory. Our analysis
provides not only the voting failure rate of a candidate but also its decay
speed, based on which the concepts of {\it the effective selection valve} and
{\it the effective expectation of merit} are introduced to help the system
designer to determine the optimal voting standard and guide a candidate to
behave in an optimal way for lowering the voting failure rate.
