In step S12, the node 101 receives the first random number R1 and the first hash value H (R1);
in step S14, the node 101 receives the purchase information sent by the user 20 to purchase a vote, the node 101 freezes a certain encryption currency of 10000 coins of the user 20, and sends the first hash value H (R1) to the first blockchain 10, so that each node of the first blockchain 10 writes the first hash value H (R1) into the first hash list by consensus; wherein the vote is an ore digging voucher of the first block chain and is used for digging after 12 hours elapse;

Taking an example that a user sends a first random number M and a first hash value H (M) of the first random number to a first block chain, and after purchasing votes successfully (the purchased votes are T (M)), and when mining succeeds, the first random number M is disclosed on the first block chain, a node verifies the first random number M, removes the first hash value H (M) from a first hash list, and makes the votes T (M) useless; wherein the process of verifying the first random number is as follows: the node calculates a first hash value h (M) of the first random number M and queries in a first hash list whether h (M) exists:
if yes, the node removes the first hash value with the value H (M) from the first hash list and makes the vote T (M) invalid;
if not, the verification is unsuccessful, the node removes the first hash value with the value H (M) from the first hash list, and the vote T (M) is invalidated;
wherein, when the validation is unsuccessful, the votes T (M) are invalidated, the frozen benefits are thawed after a predetermined second period of time has elapsed.

In a preferred embodiment, the first hash list is used to verify the first random number when the mine excavation is successful, remove the corresponding first hash value from the first hash list, and invalidate the corresponding vote, and the method further includes: after a predetermined timeout period, several benefits are thawed. During the preset overtime period, the node does not accept the purchase information of the votes sent by the first user, and the first user does not need to own the mining voucher by default; after a predetermined timeout period, the node defrosts several benefits.
The invention provides an anti-cheating block chain system, wherein a first block chain system is the anti-cheating block chain system, and each node of the first block chain is provided with a second contract and a third contract;
