Delivery Service Collaboration Using Blockchain Architecture

Due to huge developments in the e-commerce sector, the delivery service market has been growing by double digits every year. This growth has invited several collaborations on every regional level. Several third parties also join the market, partnering with the delivery services and acting as brokers. Also, most of these services are centralized, which makes them subject to single points of failure and privacy disclosure by both internal and external attackers. Moreover, they are vulnerable to denial of service (DoS) and sybil attacks launched by malicious users. As these companies have full control of the service and there is no guarantee of timely delivery, there are no provisions for penalties for delays. In this paper, we propose a blockchain-based delivery service collaboration that does not require any third or central party to control the service. The whole delivery process is implemented as a phase-lock system with smart contracts so that neither the user nor the delivery service can act maliciously. If any party tries to, then it is appropriately penalized by the blockchain.
