 Why supply chain need blockchain
 How blockchain can be used in
pharmaceutical supplychain

3. Transaction
Block
Blockchain
● Block = all transactions within a certain time period
● Blockchain = links all blocks together
Peer to Peer = No central authority
Distributed peer-to-peer network
ensures the data integrity

4. BLOCKCHAIN TECHNOLOGY
 Blockchain technology is a service provider that records information in a that makes it difficult to change,
hack or cheat.
 A blockchain is a digital ledger of transactions that is distributed across the several computers in the
network of computer systems. Each block contains a number of transactions and when the transactions are
complete the information is stored in all the computers in the network. This method of distribution and
storing is called Distributed Ledger Technology (DLT).
 In the digital ledger technology the information stored with an immutable cryptographic signature called as
hash.
 Blockchain was basically introduced for cryptocurrency, but eventually its growth is tremendous. It is
being used in many domains such as crowdfunding, voting, healthcare, E-commerce, private markets and
global payments etc.
 The main reason for its boom among the people is that blockchain stores the data in a decentralized and
secured way.
 A company instead of storing its clients information in a server of thousand computers connected under a
roof, blockchain can be used to store those information in all the nodes of the network creating fidelity of
data stored.

6. HEALTH RECORDS:
 Globally, Healthcare systems losing $300
billion each year in poor data integration.
 So, blockchain could offer Healthcare a
safe and secure system to share data more
efficiently.
 In blockchain, the data can be modified
only by certain users and the created data
can be store and retrieve data more
securely.
 In blockchain, the data is verified by a
peer-to-peer network thus eliminating
central authorities.

7.  Interoperability – blockchain can help in
improving the efficiency of interoperability
for healthcare providers.
 Blockchain can streamline healthcare, IBM’s
blockchain can streamline the network
between government, patient, healthcare
provider and health insurance provider.
 People generate more data about their own
health than ever before.
 Healthcare systems of the future will integrate
those data points to make care more personal
and collaborative information.
 Remote monitoring and blockchain will shape
where patients receive care and how providers
help keep those details private and secure.

8. SUPPLY CHAIN:

9. WHYBLOCKCHAINIS NEEDEDINSUPPLYCHAIN?
 The World Health Organization pegged global fake
drug sales at $75 billion in 2010, a 90% increase
over five years.
 Patients and retailers don’t know the origin and the
manufacturing of drugs.
 To maintain transparency in supply of
pharmaceutical drugs from the manufacturers to
the people.
 Transparency reduces the chances for counterfeit
in drugs.
 Strengthen corporate reputation through providing
transparency of materials used in products and
increase creditability and public trust in goods
shared.

10. BLOCKCHAININ SUPPLYCHAIN:
 At the time of manufacturing the manufacturer add a QR code to the product, which holds
the information like the ingredients, location of manufacturing, date of manufacturing and
expiry of the medicines.
 After manufacturing the medicines are transported to the different parts of the world.
During this transport it is necessary to maintain the medicines at specific temperature to
keep the safe. To do this the transport is made in an IOT powered vehicles in which the
temperature is maintained accordingly with the help of temperature sensors.
 Once the medicines reached the retailers/distributers, they will verify the origin and
manufacturing history of the drugs and thus add the information to the blockchain. And the
information like by whom the drugs are transported and vehicle in which they are
transported are added to the blockchain.
 After the process the drugs are distributed to the pharmacists/doctors and the patients can
trace the details of medicines by scanning the QR code with their mobile phone.
