The invention relates to a seal using method, system and device based on a self-service application mechanism and a medium, and the method comprises the steps that a using request of a user for a target seal is acquired, and the using request comprises a seal identifier of the target seal; according to the seal identifier, obtaining an approval process of the target seal and performing approval; and after the approval is passed, generating an imprint code of the target seal, and providing the imprint code to the user, so that the user can use the target seal based on the imprint code. By means of the method, a traditional physical seal using mode is changed, self-service application and self-service seal using of a whole-process applicant of physical seal using are achieved, the problem of pain points in physical seal using and the difficulties of quantitative assessment and risk management and control after seal centralized management are solved, the working process is more automatic and intelligent, and the working efficiency is improved. And the management, the node circulation and the examination of the seal work are more transparent and scientific.

According to the distributed identity management system and method based on the block chain, the identity information of the user is stored on the distributed nodes by using the characteristics of the block chain, and the security of the information is protected by using an encryption algorithm. Each user has a unique identity label, and the identity label is written into a block of the block chain and is managed and verified through an intelligent contract. The user can control the access and management of the identity information of the user through the private key without depending on a centralized identity authentication mechanism. In addition, the VC template providing the VC service is subjected to uplink processing, and the consistency and compliance of the VC certificate are ensured from the source. According to the invention, the problem of verification information forgery of the distributed identity management system can be solved, and the security and credibility of identity verification are improved.

This invention discloses a composting method and intelligent composting system based on garden waste. The composting method based on garden waste provides a homogeneous and optimized material basis for efficient fermentation through intelligent pretreatment and dynamic formulation of raw materials. During fermentation, a three-dimensional sensor network is deployed and a synchronized digital twin model is constructed. The model is used to predict the future evolution of internal temperature, oxygen, and microbial activity within the compost pile. The degree of composting is intelligently determined by a multi-source information fusion model. The matured material undergoes multi-stage screening to produce a series of products, and a unique traceability code links the entire process to a digital archive, achieving quality traceability. This invention also provides an integrated system for implementing this method. This invention achieves predictive intelligent control and clean production in the composting process, significantly improving processing efficiency, product quality, and resource utilization, while effectively controlling operating costs and environmental pollution.
