Sampling detection-oriented block chain system and implementation method thereof

The invention discloses a sampling detection-oriented block chain system and an implementation method thereof, and the method comprises the following steps: S1, deploying block chain sub-nodes in each level of sampling inspection unit according to sampling inspection links, and dividing the sub-nodes of the same link in each level of sampling inspection unit into the same fragment through a fragment technology; and S2, enabling each block chain sub-node to obtain spot check result data obtained based on the Internet-of-Things technology in the respective spot check link, only perform consensus in the corresponding fragment in the consensus stage, and independently upload the data to the block chain after performing consensus in the respective fragment. 本发明公开了一种面向抽样检测的区块链系统及其实现方法，所述方法包括如下步骤：步骤S1，按抽检环节分别在各层级抽检单位部署区块链子节点，并通过分片技术，将各层级抽检单位中相同环节的子节点划分进同一个分片中；步骤S2，各区块链子节点于各自抽检环节获取基于物联网技术得到的抽检结果数据，在共识阶段只在其对应的分片内进行共识，在各自的分片内进行共识后独自上传至区块链。
