数字经济是以数据资源为关键要素，以数字科技为支撑的经济形态。数字产业化和产业数字化是数字经济中的重点内容，数字产业化主要是推动数字科技形成规模化产业，产业数字化主要是利用数字科技支撑和推动传统产业转型升级。在这个过程中可以基于区块链等数字科技推动信息技术服务加速数字产业化，依托元宇宙的新场景拉动信息消费促进产业数字化。
In the era of Web 3.0,sensors are involved in the detection and identification of planting,transportation,processing and sales.Based on the recognized premise that sensor detection data is true and reliable,artificial intelligence judgment is made through the data collected by sensors in each link(i.e.evidence data),and the performance is performed by smart contracts.
struct block_header{

struct wait_weight{
uint32_t wait_sec;
uint16_t weight;
EOSLIB_SERIALIZE(wait_weight,(wait_sec)(weight))
};需求及模式详细：MrsFu123
该结构体没有什么特别的，陌生的部分仍旧只有第一个参数wait_sec，但通过字面含义即可理解，就是等待的秒数。
struct authority{
uint32_t threshold=0;
std::vector<key_weight>keys;
std::vector<permission_level_weight>accounts;
std::vector<wait_weight>waits;
EOSLIB_SERIALIZE(authority,(threshold)(keys)(accounts)(waits))
};
