Scrutinizing Trust and Transparency in Cash on Delivery Systems.

Most of the current decentralized blockchain approaches have disadvantages that need to be improved to have efficiency and completion. First, there is no motivation for any participants to take action honestly. Seller, buyer, and shipper do not trust each other completely. Second, the delivery depends on a trusted third party or arbitrator to act as a deposit and keep all the money from the start of the sales process until the end. Only a trusted third party who keeps money could be a focal point of failure and also costly. Moreover, there is no dispute settlement mechanism if it occurs. Therefore, there will be a loss for the seller, buyer, or both sides for any acts of dishonesty. In this article, we review technology deployment and develop distribution solutions using blockchain technology. We use Hyperledger Composer in our system to protect the rights of merchants and smart contracts to remove any third party or arbitrator.
