One more problem faced by the healthcare industry is about drug traceability. There are a lot of counterfeit drugs in the market and these counterfeit drugs lead to the loss of money as well as lives. To counteract such fake drugs, we can create a blockchain based solution for drug supply chain integrating. For this solution, every drug can be issued a unique ID based solution for its tracking. A separate blockchain ledger can be initiated for the government approved drug suppliers. This separate ledger will provide the source of truth to other parties making sure that the drugs are only available from the government approved drug suppliers.

Moreover, patients purchasing the drugs can also be recorded over the blockchain for verification of the drugs. available in the market. Finally, drug traceability can also be benefited by the use of smart contracts, which can be initiated between the suppliers and distributors. This will create a permanent storage and transparency of drugs, which is required in the market. It will also reduce the number of counterfeit drugs, as the distributors and other third parties can verify the drugs from the government approved drug ledger. The benefit of using such a solution is that it will provide visibility which is required for critical decisions.

Moreover, it will reduce the loss due to counterfeit drugs. As now the distributors third parties and patients can verify the government approved drug suppliers from the blockchain directly. It will also protect consumers and brands Through reduction of fake pharmaceutical companies, drug rights can also be maintained using the blockchain. Now let's go and visualize the use case with the help of a diagram. You can see in the diagram shown here we have a drug manufacturer. The drugs manufacturer has different type of data available with him, such as packet label, drug items created and the drug items being packed.

The manufacturer uses the blockchain API to generate a blockchain transaction. This transaction record shows the manufacturing details and also the timestamp for the creation of drugs. This transaction is uploaded over the blockchain as per the drug identity key. The distributor can verify the details about the drugs using the blockchain by either using a mobile Our web application. The distributor will then take the drugs packet authenticated from the ledger and supply to the hospitals, pharmacies, and online pharmacies. for carrying out such process distributor will also use the blockchain API to generate one more transaction with the same drug identification key.

This transaction will be holding the details about the distribution of the drugs and will be in continuation with the transaction created by the manufacturer. By using the drug identification key, we are building a complete sequence of records through which every drug could be traced back to its origin. hospitals, pharmacies, or the online pharmacies can again validate the data provided by the distributor through blockchain whenever the drugs are to be sold off to the users blockchain transaction is again created, depicting the user time for sale and cost. pharmacies and hospitals will also use a peer to generate blockchain transaction and store the permanent record over the blockchain. in continuation with the previous records, as per the drug identification ID, the patient or the user receiving the packet of drugs can see the transparency for the whole process through the blockchain. Patients will be able to see how the drugs are manufactured, how the distribution took place, and how the hospital or pharmacy managed the drugs.

They can also see the timestamps related to all the services, thus giving them the correct guidelines for expiry and repurchasing of the drugs. This process of providing transparency will help all the parties involved and reduce the counterfeit drug Inside the market
