Abstract:
At present, counterfeit drugs poses a serious threat, as it is difficult for people to know the true value of purchased medicines due to a significant lack of transparency in the current system. Our solution is a use of a powerful technology, which is emerging now a days vary rapidly because of crypto world known as Blockchain. It is an open, distributed ledger that can efficiently record transactions between two parties in a verifiable and permanent way. Since blockchains are decentralized, distributed, transparent, and immutable, they can easily solve counterfeit medicines. It shows loyalty and enables easy access to blockchain-based medical items. Each product within the chain can be transferred between authenticated entities of the chain using an event request-response mechanism. All transactions between entities are recorded into the blockchain using smart contracts with the help of which a product can be traced to its source. A DApp is developed using React Framework, to show the interaction between the user and the contracts. The smart contracts were deployed on a local blockchain provided by Ganache. Using Web3.js and Truffle framework, DApp is connected to the blockchain. Secondly, a scanner which is integrated into a react made web application which shows tracing, records of medicines, and enhancing blockchain-based credit evaluation. The experimental results show that our solution is feasible and comparatively more secure than any existing systems
