How Blockchain is Shaping the Healthcare Industry

Defining Blockchain

A Blockchain refers to a timestamped series of immutable data records that are managed by a cluster of computers that are not owned by any single entity. Each of the blocks of data is secured and are bound to each other by the use of cryptographic principles, known as chains.

The Blockchain network holds a no-central authority. It is shared, and an immutable ledger and the information being stored is open for everyone to see. Any data built on the Blockchain is very transparent, and hence, everyone is accountable for their course of action.

Costs Involved in Blockchain

A blockchain has no transaction costs involved. There is an infrastructure cost, but no transaction costs exist. It is a simple and ingenious method of passing on information from a source to a destination in a fully automated and safer way. One of the parties involved needs to initiate the transaction by creating blocks. The designed block is verified by a vast number of computers present around the net. The verified block is then added to a chain and stored across the net by creating not only a unique record but also a unique record that has a unique history. When a single record is falsified, the entire chain having millions of instances is even falsified, and it becomes virtually impossible. Bitcoin has now and then using this model for carrying out the monetary transactions, and it can be deployed in various other ways as well.

The Blockchain can not only transfer and store money, but it can also replace the processes and business models that are dependent on a small fee for carrying out transactions or any other type of transaction between both parties.

Industry Adoption of Blockchain in India (for 2019)


 Working of Blockchain

The information that is held on a blockchain exists as a shared and a continuous-reconciled database. This method of using the network which holds several apparent benefits. The database of the Blockchain isn’t located or stored in a single location, i.e. the records are kept public and easily verifiable. There is no centralized version of this information that exists for any hacker to corrupt. The information is hosted by millions of computers present in the network, and the data is accessible to anyone present on the Internet.

Reasons for Blockchain Being Successful

Following are some of the reasons why blockchain has become successful-

  1. Not owned by a single entity and hence there are no issues of centralization
  2. Data is stored in a cryptographic method
  3. Blockchain is immutable, thus no one can tamper or alter the data inside the blockchain
  4. The blockchain is fully transparent, so it is easy to track the data by the user according to their needs

Properties of Blockchain Technology

  1. Increased Capacity
    One of the most remarkable features of Blockchain is that it can increase the capacity of the entire network. As there many computers working together, combined offer a high power than a few devices where the things are centralized
  2. Better Security
    Blockchain Technology holds better security because there is no chance of shutting down the systems. Several computers known as nodes secure the blockchain network, and these nodes are responsible for confirming the transactions on the network
  3. Immutability
    The creation of immutable ledgers is one of the significant values which drives Blockchain. Any centralized database is prone to get hacked, and hence, these require trust in the third parties for keeping the database secured
  4. Decentralized System
    Decentralized technology gives users to store their assets inside a network which is further accessed using the Internet. The asset could be either a contract, a document, etc. By this, the owner holds direct control over his account giving the owner that power to transfer the assets to anyone he wishes

New Applications of Blockchain

The newer business applications that will rise from Blockchain includes the following-

  1. Smart Contracts
    The distributed ledgers allow the coding of simple contracts that are going to get executed when a set of specific conditions are met. At this stage of technological development, smart contracts can be programmed for performing simple functions
  2. Shared Economy
    By enabling peer-to-peer payments, the Blockchain has opened ways for directing interactions between the parties, which is a genuinely decentralized result of economy sharing
  3. Governance
    Making the results fully transparent and accessible to the public, the distributed database technology can bring full transparency in elections or any other processes which involve poll taking
  4. Auditing of Supply Chains
    The distributed ledgers can provide an easy way for certifying the genuineness of the products being purchased. Transparency is achieved by a Blockchain based time timestamping of a date and location which can correspond to a product number
  5. File Storage
    The decentralized file storage brings in a lot of benefits. Distribution of data throughout the network can protect the files from getting hacked or lost
  6. Prediction Markets
    The crowdsourcing of predictions on an event is proven to have a higher degree of accuracy. Averaging opinions can cancel out the unexamined biases which could distort the judgment
  7. Identity Management
    There has been an increased need for better identity management on the Internet. The ability to verify an individual’s identity has remained the anchor for all the financial transactions happening online. The distributed ledgers have offered enhanced methods for proving an individual’s identity along with the possibility for the digitization of personal documents
  8. Anti-Money Laundering and KYC Practices
    The practices of anti-money laundering and KYC practices are becoming a strong potential that needs to be adopted by the blockchain technology. The financial institutions need to perform a lab labor-intensively-step procedure for `every new customer. The KYC costs can be reduced by cross-institutional client verification and also increasing the monitoring and analysis effective at the same time

Capital Investment in Blockchain

How Blockchain Benefits the Healthcare Industry

The healthcare industry should look to invest in Blockchain technology to gain the following benefits-

  1. Easy Exchange of Health Data

The exchange of health data is one of the essential features of Blockchain in the healthcare industry. The healthcare startups can use the blockchain-enabled IT systems for delivering technological solutions for many challenges, which include health data security and interoperability.

The blockchain technology gives healthcare data exchange systems a seamless action to the real-time patient data by eliminating the cost and burden of data reconciliation

  1. Building Smarter Contracts for Flexibility

The blockchain technology makes it possible to develop smart contracts. The smart contracts allow the doctors to carry out the information exchange with more flexibility and freedom, inline with the health-related decisions which are made, be it a patient willing to choose to disclose his health records or even a doctor sharing information with his fellow doctors

  1. Resolving Challenges of Cybersecurity

The healthcare industry is known for its strict policies and regulations, ensuring the security and privacy of the data.  With the increase in the number of cybersecurity threats, new problems are created for emerging digital workflows.

As it is not possible to hack or modify the data saved on the Blockchain, this technology can help in resolving the cybersecurity challenges faced in the industry

  1. Reducing Costs and Gaining Efficiency

The healthcare-related organizations and firms can use the Blockchain for record management as well as bridging the traditional data silos, thereby increasing the efficiency and keeping the medical data safe. This technology would also streamline the entire process for patients to access their medical records and securely share data. By using the blockchain technology, the transfer of medical records between two institutions is likely to decrease, thereby making the process of auditing much more manageable.
