Referring to fig. 1, fig. 1 is a flowchart illustrating a method for managing a job ticket based on a blockchain according to an embodiment of the present invention. The execution main body of the method described in the embodiment of the invention is an execution main body composed of software or/and hardware, and the execution main body can receive related information in a wired or/and wireless mode and can send a certain instruction. Of course, it may also have certain processing and storage functions. The execution body may control a plurality of devices, such as a remote physical server or cloud server and related software, or may be a local host or server and related software that performs related operations on a device that is located somewhere, etc. In some scenarios, multiple storage devices may also be controlled, which may be located in the same location or in different locations than the devices. As shown in fig. 1, the job ticket management method based on the blockchain includes the following steps:
s101: receiving application information of an application node submitting a job certificate;
s102: verifying the authenticity of the operation certificate application information, and if the verification is passed, storing the operation certificate application information into a block chain; the job ticket application information is job application information submitted by an application node based on job requirements;
the first two steps are mainly the contents of submitting the operation certificate information and verifying the operation certificate information by the application node, in the embodiment of the invention, the application node refers to the application party, and more preferably, the application party is a unit or a department in specific implementation, and the operation certificate application is carried out by the unit or the department, so that the application is more convenient to carry out the responsibility following by taking the department as a main body. The job ticket application information in the embodiment of the invention comprises an application unit, an operator and job contents; the operation license is mainly a special operation license in the field of safe production, such as a fire operation license, a limited space operation license, a temporary electricity operation license and the like; these special operations are dangerous and therefore need to be approved and confirmed by the relevant departments before they can be issued.
When the authenticity verification of the application information is carried out, verifying the authenticity of the application data by a verification service according to a preset rule, and storing the verified operation certificate application information on a blockchain; the authenticity detection is automatic detection, and can automatically detect whether the material submitting the operation certificate is true, such as identity card inspection, graduation detection, whether a health commitment book is signed, special operation certificate detection and the like, and whether the material submitting the operation certificate is true or not can be determined by detecting the certificates; when the method is implemented, the names of the identity card, the graduation card and the health commitment book can be detected uniformly to judge whether the actual operator is real or not; besides the above, the signature written by the health commitment can be intercepted, so that the follow-up information searching is facilitated.
S103: the operation certificate application information is sent to a certification node for state verification, the certification node is inquired about operation certificate state information related to the operation certificate application information, if a corresponding operation certificate exists, the operation certificate is returned to the application node for state verification, and if the corresponding operation certificate does not exist, the operation certificate is issued at the certification node and stored in a blockchain;
