【Abstract】Supply chain management speeds up the delivery system and product flow towards customers. It is required to update the delivery system and fulfill the customers' needs. Still, Centralized delivery management approaches are very risky and unsatisfactory, so nowadays, decentralized models are more secure and customer friendly. However, delivering a particular customer in decentralized models is a rigorous task with anonymity or pseudonym. Therefore we propose a location-based decentralized delivery system that provides accurate delivery of products to customers. It is crucial for sellers, Buyers, and Transport service providers that the claimed location is trustworthy and publicly verifiable. The proof of location guarantees the correct geographic location, and the witnesses provide location confirmation to the prover. Further, We introduce an off-chain multiparty payment channel with a supply chain for quicker and more secure payment, and it is free from "flood and loot attacks" and intermediary insecurities. The proposed scheme is protected against malicious activities all involved entities attempt, and smart contracts solve the monopoly. The implementation result uses the ethereum network and shows the gas consumption of different smart contracts with execution costs. Finally, we proved that location verification, disputes solved and successful payment completion are much better than all existing models.
