A blockchain is a decentralized ledger that records all peer-to-peer transactions in a public network.
Participants can confirm transactions without the help of third parties like a bank.
Financial services, insurance claims, trade settlements are all possible applications of a blockchain.
Continue reading this blockchain technology review to know more about its benefits and other applications.

What Is A Blockchain?

What is Blockchain?

Blockchain is a distributed, unchangeable public ledger that makes recording transactions and monitoring assets in a corporate network easier.
It is secure since the edger can only be accessed or edited with the permission of that network user.
Orders, payments, accounts, production, and others are all tracked via a blockchain network. 

How Does Blockchain Works?

A blockchain’s core concept can be broken into four separate, continuous steps:

Documentation Of The Transactions

It creates a record of all the participants in the network.
The participant enters the transaction that requires the digital signature of each participant for the verification process.

Double-check The Transactions To Ensure Accuracy

At this stage, the nodes verify the computers connected to the network to ensure that the trade is authentic.
The completion of the transaction requires approval from all the participants.

The Blockchain Block Records The Transactions

The following process is to hash the block.
The hash figure is a fixed-length value.
It is a unique code that identifies the block and specifies its location within the blockchain.
The function of the hash is to confirm that no one has made any changes in the transaction.


Soon the block of the blockchain ends.
It brings the blockchain construction and certification process to a close.
Later, the process of building the next block starts within few seconds.

Pros Of Blockchain 

Here are some of the benefits of blockchain technology:

  • Due to real-time transactions, time effectiveness has increased.
  • Direct transactions cut out the middleman and save money.
  • It reduces cybercrime, fraud, and tampering threats.
  • More transparent processes, with sufficient record-keeping and tracking.
  • Cryptographic and decentralized Blockchain protocols provide a high level of security.

However, blockchains have several limitations, such as the limit on transactions per second.
Since it relies on a broader network to approve transactions, there’s a limit to how fast it can proceed.

Applications Of Blockchain

Let’s look at how blockchain is benefitting the world:

For Identification

Blockchain offers the potential to provide a uniform network of identification data that can be securely stored, accessed by a limited number of institutions, and certified in real-time. 

In Finance

The financial services provided by blockchain include onboarding, record-keeping, customer screening, privacy, data management, transaction, security, and trade processing.

Supply Chain 

When it comes to supply chain management, blockchain is quite beneficial.
Businesses can swiftly detect inefficiencies in their supply chains and find products in real-time by eliminating paper-based trials.
Furthermore, blockchain would enable companies and maybe even consumers to monitor how products performed in quality control as they moved from their point of origin to the store.

In Insurance

Customers and insurers can manage claims clearly and securely thanks to smart contracts by blockchain.
All the contracts and claims may be stored on the blockchain and authenticated by the network, which would reduce invalid claims by rejecting numerous claims for the same accident.

Final Thoughts 

The blockchain is beneficial in a variety of ways.
Business processes have risen to the next level with the advancement in blockchain technology.
Blockchain technology provides more transparency and efficiency than the existing business processes.
