The rapid rise of e-commerce has generated an increased need for efficient and safe solutions for last-mile delivery. This study presents a hybrid vehicle routing framework that combines companyowned vehicles with crowd-sourced drivers and uses a blockchain-based system to improve operational transparency and trust. The proposed framework is based on an optimization model that reduces overall delivery costs while meeting capacity and time window restrictions. In addition, smart contracts are used to construct a blockchain component that records route proposals, delivery transactions, and payment confirmations in an immutable manner. This integration not only optimizes the routing process but also offers decentralized verification of delivery events, which reduces the need for central authorities and helps to prevent fraud. A reliable and economic answer for current last-mile logistics is provided by the one-of-a-type integration of blockchain verification mechanisms with advanced optimization algorithms. The proposed framework has significant implications for improving delivery efficiency, enhancing service reliability, and reducing the environmental impact of urban transportation.
