Blockchain technology can improve traceability in the Indian pharmaceutical supply chain. The document proposes a blockchain-based protocol to track ownership of pharmaceutical goods across the supply chain. Key steps include manufacturers registering products on the blockchain, ownership transfers being recorded, and current ownership being verifiable. This would allow for authentication of goods and more transparency while protecting privacy. The conclusion discusses how blockchain could enhance security, transparency, and immutability in the Indian pharmaceutical supply chain.

1. Blockchain enablers in Indian
Pharmaceutical Supply Chain

2. Abstract

3. Introduction
• The healthcare supply chain is a complicated web of numerous independent businesses, including retailer
pharmacies, hospitals, manufacturers, stockiest, sub-stockist, distributors, and raw material suppliers. Due to a
number of issues, including a lack of information, centralized control, and rivalry among stakeholders,
tracking goods across this network is challenging.
• Drug traceability (track and trace) is becoming more and more important, and many nations throughout the
world are implementing new technologies.
• Blockchain technology gives supply chain participants more privacy protection, data transparency, and
tamper-proof systems (Min2019).

4. Methodology
• Proposed Pharmaceutical goods Traceability Protocol.
• Enrolment of a Device by the Manufacturer.
• A manufacturer (M) can register an item by sending the smart contract OC the transaction register goods. In the
transaction, the manufacturer may additionally provide any required related data, such as the goods’ identification
and verification information (PUF data)
• Procedure for Ownership Transfer
• The present owner and the new owner are referred to as the supply chain participants such as manufacturer and the
stockist, sub stockiest distributor respectively, in this work.
• Verification of the Ownership Data
• The stockist asks the smart contract's check Ownership() method to confirm the facts of current ownership. If the
response is True, the stockist can confirm the manufacturer's legitimacy at this time.
• Authentication of the goods
• A product's ownership cannot be established simply by checking. A dishonest stockist might swap out the genuine
product for a replica and market it to the sub-stockist or end consumer
• Money transfer
• Each supply chain participant for example stockist pays the manufacturer when the pharma goods has been certified
and the manufacturer’s ownership of the goods has been confirmed
• Implementing Transaction for Ownership Transfer
• The goods with (goods identifier) is transferred from the one supply chain actor to the supply chain participants
using this function.

8. Conclusion
• The very purpose of this study is to investigate and highlight the main characteristics of the Blockchain.
What are the enablers of the blockchain and their features to enhance the supply chain of the Indian
Pharmaceutical industry.
• By shedding light on the importance of traceability, transparency, security, decentralization and immutability
that can be achieved by the blockchain in the Indian pharma supply chain.
• Therefore this study provides the potential impacts of blockchain on the Indian Pharma supply chain. This
study shows the effect of blockchain through the framework.
