The use of blockchain applications is more than cryptocurrency. Although the success of cryptocurrencies made it relevant.

In this post, we’ll discuss the use cases of blockchain. Also some of its challenges. But before diving into its use cases; let’s do a quick background check.

And, if you don’t know already, let’s get to know what blockchain is.

What is Blockchain?

Long story short, blockchain is a secure and transparent database system. It stores the data in blocks that are chained to one another. Allowing secure and transparent transactions.

It’s decentralized, which means there is no central controlling authority. Computers & called nodes do the heavy lifting. They confirm these transactions and add them to the digital ledger.

Blockchain is most useful in industries that need secure, and transparent record-keeping.

The History: How Blockchain Came Into Existence?

Research scientists Stuart Haber and W. Scott Stornetta first introduced blockchain in 1991. They introduced a way to mark documents with timestamps. It became difficult to change or backdate the information.

Moving forward, computer scientist, Hal Finney developed digital cash. It’s called Reusable Proof Of Work(RPoW). Early steps of creating cryptocurrency. RPoW allowed users to exchange proof-of-work tokens. It was like a ticket that proved a person has done some computational work. This made it difficult to fake these tokens.

Later on, Satoshi Nakamoto conceptualized and improved distributed blockchain. He created a unique method to add blocks. It doesn’t need signatures from trusted parties. The improvement was beneficial enough to become the backbone of all cryptocurrency. In the cryptocurrency space, it’s serving as a public ledger for all transactions.

Now that we have a brief idea of blockchain and its history. Let’s explore some of its challenges.

The Challenges Of Using Blockchain

Lack Of Adaptation

Blockchain isn’t broadly accepted. APCQ discovered 29% of organizations are experimenting with or using blockchain. Blockchain works best when used across a wide network. A blockchain ecosystem needs more than just users. It needs the suppliers to join the network too. And, without broad approval blockchain will remain ineffective.

Initial Cost

Blockchain is still in its early days. And, finding skillful developers is expensive. A mining rig consists of several servers and giant computers. This consumes a lot of electricity. That’s near unaffordable.

Energy Consumption

Blockchain networks need a lot of energy to function. Equal to an entire country. Efforts are there to make it energy efficient. Which still remains a great concern for long-term sustainability.


Blockchain architecture is distinct. Some are less secure than others. The decentralized ones are more vulnerable. It leaves all public blockchains at risk of 51% attack.

Public Perception

People don’t trust blockchain as a conventional solution. The majority think that it won’t last for long.

Integration With Legacy System

Organizations may have to rebuild from scratch. As it’s impossible to integrate blockchain with their legacy system.

Identifying A Good Use Case Of Blockchain

A good use case of blockchain should have the following:

1. A Business Problem That Blockchain Can Solve

Some notable blockchain features are

  • Decentralization
  • Immutability
  • Transparency
  • Security
  • Efficiency
  • Traceability, etc.

Solving business problems in various industries.

2. Identifiable Business Network

An identifiable business network offers increased security, efficiency, and transparency. All network transactions are visible to participants. Improving transparency and reducing the chance of fraud.

3. Trust Issues in Information Exchange

Transactions on the blockchain are secure and transparent. Reducing lack of confidence in information transmission.

Ways Blockchain Can Be & Is Being Used

Blockchain is a versatile technology that can be used in a variety of industries. Let’s jump into — how blockchain can be & is being used currently.

In Government Organization

The followings ways blockchain can be and in some is being used countries in

  • To store and manage digital identities
  • secure voting systems
  • Track and trace government assets, etc

In Healthcare Industry

The followings are some blockchain use cases in the healthcare industry:
  • Secure sharing of medical data
  • Improved interoperability
  • Medical Supply Chain Management
  • Transparent Clinical Trials
