Summary:The invention relates to a block chain consensus mechanism based on contribution values and credibility. By dynamically adjusting the target difficulty value of the Hash calculation, the time and power for calculating the random number are reduced; secondly, introducing contribution values, creditworthiness and a reward and punishment mechanism, endowing each node with the contribution value and the creditworthiness, calculating nodes with random numbers within a specified time, obtaining contribution value rewards, and increasing or deducting the creditworthiness according to node behaviors; and finally, nodes are added to calculate random number time, weights are calculated according to the contribution value, the credibility and the calculation time to obtain a final value fValue, and the node with the maximum fValue obtains the packaging bookkeeping right. Experimental results show that the PoCaC can improve the block output speed, reduce the waste of computing power and balance the accounting right compe
