The system includes a mobile communication device, a web-based interaction component, and a service control system. The system includes a service interface device to generate an electronic signal. The electronic signal includes a first SMS transmitted to the mobile communication device and a second SMS transmitted to the service control system. The electronic signal also includes a first secured hash link executable by the mobile communication device, wherein executing the link records a first electronic evidence of service delivery. The electronic signal includes a second secured hash link executable by the service control system, wherein executing the second link records a second electronic evidence of service delivery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Blockchain-enabled service delivery evidence system","description":"A system is provided for automated recording of evidence of delivery of a service in a service setting.
