Involving reliable, trustworthy and transparent features of the blockchain technology in payment systems are indispensable criteria for boosting businesses and increasing the efficacy of different processes. In this regard, our paper provides a non-trivial study in embedding the blockchain technology into the payment systems of initiating a small business as well as donating procedure in disaster based application. To do so, current standard instructions for both cases are firstly analyzed. Then, the drawbacks of current payment system in these applications are elaborated. Next, it is demonstrated how the proposed blockchain framework evolves the traditional payment systems and flourishes the previous business process of corresponding cases. Using graphical and pseudo code-based representation, the underlying mechanism of the smart contracts associated with the blockchain technology are also highlighted.
