Abstract: The present invention is a system and method for secure distributed package shipping logistics using automated sorting facilities and dynamic routing. In an embodiment, end-to-end security is provided by use of blockchain-based Smart Contracts. Cloud-based dynamic routing software pairs packages with available crowd shippers based upon criteria determined by the shipper. The dynamic routing software facilitates secure bailment and efficient transfer of packages with a minimum of interpersonal interaction. The system is suitable for individual or bulk package shipments, and can route for specific criteria such as “shortest travel distance,” “shortest travel time,” or “lowest cost.
