Blockchain-Based Solution for Proof of Delivery of Physical Assets

摘要: To date, building a highly trustworthy, credible, and decentralized proof of delivery (POD) systems to trace track physical items is very challenging task. This paper presents blockchain based POD solution shipped that uses smart contracts Ethereum network, in which tracking, tracing activities, logs, events can be done manner, with high integrity, reliability, immutability. Our incentivizes each participating entity including the seller, transporter, buyer act honestly, it totally eliminates need for third party as escrow. proposed ensures accountability, punctuality, integrity auditability. Moreover, makes use Smart Contract Attestation Authority ensure code follows terms conditions signed by entities. It also allows cancellation transaction transporter on contract state. Furthermore, ask refund certain justifiable cases. The full code, implementation discussion sequence diagrams, testing verification details are all included part solution.
