The problem DaanVeer solves

During the crisis of COVID-19, many countries are trying to fight with this pestilence by putting all their resources. In this situation, even the help of penny means a lot for the country's government and its citizens. According to The India Giving Report:

A total of 84% of people donated money to an individual or an organization.
27% gave money to a charitable organization.
70% preferred to donate directly to beneficiaries.
52% of donors believe that a ‘lack of transparency hinders donations to NGOs.
From the above point, A total of 84% of people donated in which 27% of people donated to NGOs or charitable organizations. From the third and fourth points, it is clear that most of the people donated directly to beneficiaries so that they can see how their donation is being used. Lack of donations in NGOs is because they don't know how their donation is being used. DaanVeer is a Blockchain-based donation app running on a decentralized system in which donators can easily donate to the registered NGO's. All the transaction occurred on Ethereum platform uses Ether as a transaction digital currency. The app removes the control of the central authority. All the Transaction history is maintained in a blockchain network. Blockchain makes the app more secure, trustable, and fast. The use of it made donators know where their money is used which probably increases the percentage of donation in India.

Challenges I ran into

Could Blockchain revolutionize philanthropy?
This question stuck In my mind and I start searching about it. I found a lot of research papers based on philanthropy revolution but I am not getting an actual idea of how to store a transaction through the blockchain network. After searching a lot about smart contracts helps to solve a problem.
