Blockchain is a distributed, unchangeable ledger that makes recording transactions and monitoring assets in a corporate network easier. An asset can be tangible (a home, vehicle, land, or cash) or intangible (intellectual property, patents, copyrights, branding). On a blockchain network, virtually anything of value may be monitored and sold, lowering risk and cutting costs for all parties involved.

There is a certain amount of trust associated with blockchain technology. The improved security, more transparency, and rapid traceability of blockchain are the foundations of this trust. Beyond issues of trust, blockchains offer a slew of other economic advantages, such as cost-saving via greater speed, efficiency, and automation. Blockchain decreases overhead and transaction costs by drastically decreasing paperwork and mistakes. It also reduces or eliminates the need for third parties or middlemen to validate transactions.

What is Blockchain?

Blockchain is a method of storing data in such a manner that it is difficult or impossible to alter, hack, or defraud it.

A blockchain is a digital log of transactions that is copied and distributed throughout the blockchain’s network of computer systems. Each block on the chain comprises a number of transactions, and whenever a new transaction happens on the blockchain, a record of that transaction is added to the ledger of each participant. Distributed Ledger Technology (DLT) is a decentralized database that is controlled by numerous members.

According to CryptoNewsZ, A blockchain is a form of distributed ledger technology in which transactions are recorded using a hash, which is an immutable cryptographic signature.

This implies that if a single block in a chain is altered, it will be immediately evident that the chain has been tampered with. Hackers would have to modify every block in the chain, across all distributed copies of the chain, if they intended to damage a blockchain system.

Blockchains like Bitcoin and Ethereum are constantly expanding as new blocks are added to the chain, increasing the security of the ledger substantially.

How Does Blockchain Work?

Blockchain transactions work in a rather simple and straightforward manner. The process is not very complicated and even a layman will not find it very hard to comprehend. The setup of blockchain transactions is mentioned below.

  1. The first step of a blockchain transaction is someone requesting a transaction involving contracts, cryptocurrency, records, or some other information.
  2. With the help that nodes provide the transaction that has been requested is broadcasted through a network of P2P.
  3. The nodes’ network validates the status of the user and the transactions with the help of certain algorithms.
  4. Once that transaction has been completed, the newly created blockchain is then added to the previously existing one. In this way, it becomes unalterable and permanent.

Benefits of Blockchain:

There are a number of benefits that blockchain offers. Some of the benefits of blockchain technology are mentioned below.

  1. Blockchain offers a higher level of accuracy by eliminating human involvement in the process of verification. 
  2. Since blockchain technology does not require any involvement from third parties, the cost is also reduced. 
  3. The aspect of decentralization also makes it more secure and rather difficult to mess with.
  4. The transactions made are very safe and secure in nature.

Uses in Industries:

Although Bitcoin’s prominence helped to illustrate blockchain’s use in banking, entrepreneurs have come to feel the technology has the potential to change a wide range of sectors. The application of a transparent, verifiable register of transaction data is essentially limitless — especially since blockchains function on a decentralized platform with no need for central oversight, making them fraud-resistant.

According to blockchain news, Companies are raising awareness of blockchain technology in industries ranging from infrastructure to public policy as they utilize it to create more openness and authenticity across the digital information ecosystem.

Some of the industries that can be hugely benefited by blockchain technology are services related to finance, infrastructure, mobility and travel, healthcare, retail and CPG, public sector, entertainment, mining and agriculture, information service, education and communication, and various other industries. 

Advantages & Disadvantages:

Despite its intricacy, blockchain’s potential as a decentralized record-keeping system is nearly limitless. Blockchain technology may have uses beyond those listed above, ranging from increased user privacy and security to reduced processing fees and fewer mistakes. However, there are certain drawbacks.


  1. The transactions made on blockchain are extremely secure, efficient, and private.
  2. The chances of error are less in blockchain technology because of the elimination of human involvement. 
  3. For people of countries with insecure or undeveloped governments, blockchain provides a financial option and a method to safeguard personal information.
  4. The blockchain system is extremely transparent and the chances of hidden scams or fraud are almost zero. 


  1. The cost associated with blockchain technology is quite significant as it comes with mining bitcoins. 
  2. The rate of transactions per second is low on blockchain technology.
  3. The issue of regulation is a major one in this sector, which often contributes to the disadvantages of blockchain.
  4. Blockchain also has a proven history of being used in illegal activities and that is another downside of this technology. 


Keeping in mind all the hype that blockchain is getting, it can be safely said that blockchain technology deserves the hype. Given the number of advantages that it offers to its users, it is no wonder that more and more people are becoming interested in knowing and understanding blockchain technology.

A number of industries will be hugely benefited if blockchain technology is used on a larger scale. The chances of mistakes will be reduced and there will be less human involvement in the process of transitions and that would ensure a smoother process and experience for the users. 

However, a user should gain enough knowledge and understanding about how blockchains work before hopping into the blockchain train.
