其中，如图1所示，云签署电子凭证的上链存证过程包括以下步骤：Among them, as shown in Figure 1, the on-chain storage process of cloud-signed electronic certificates includes the following steps:
第一步：二级保全系统通过证据采集接口对完成云签署的电子凭证进行数据采集，并将采集到的源数据文件进行存储；Step 1: The secondary security system collects data from the cloud-signed electronic certificate through the evidence collection interface, and stores the collected source data files;
第二步：二级保全系统对采集到的源数据文件进行哈希计算得到哈希值；Step 2: The secondary security system performs hash calculation on the collected source data files to obtain the hash value;
