What are the benefits of using a blockchain?

Some companies have already incorporated blockchain technology, including Walmart, Pfizer, AIG, Siemens, and Unilever. IBM has created its Food Trust blockchain to track the journey of food products from farm to table.

What are the benefits of this approach? Foodborne illnesses are common in the food industry, and hazardous materials have been accidentally introduced to food products on a number of occasions. Blockchain is being used to track food products so that outbreaks can be traced back to their source and the cause of sickness can be determined.If a food is found to be contaminated, the company can trace the food back to its origin and identify any other products it may have come in contact with. There are many different ways in which blockchain technology is being used in practice, and this is just one example.

Benefits of Blockchains

The benefits of using a blockchain include its accuracy and the many transactions that are carried out on it. This method of verification eliminates the need for human intervention, leading to fewer human errors and an accurate record of information. Even if a computer on the network makes a computational mistake, the error will only be made to one copy of the blockchain.For the error to propagate to the rest of the blockchain, it would need to be made by at least 51% of the network's computers. This is an extremely difficult task for a large and growing network like the blockchain.

Cost Reductions

Reducing the cost of transactions can save consumers money. Blockchain eliminates the need for third-party verification, which means that businesses no longer have to pay fees associated with processing payments using credit cards. Central authority is a trusted third party that offers low transaction fees.


Blockchain is decentralized, meaning that it does not store any of its information in a central location. Instead, the blockchain is copied and distributed throughout the computer's network. Whenever a new block is added to the blockchain, every computer on the network updates its copy of the blockchain. This makes it harder for someone to tamper with the blockchain. Only one copy of the information, not the entire network, will be compromised.

Secure Transactions

To ensure the security of a transaction, the blockchain network must verify its authenticity. Thousands of computers check the details of the purchase to confirm that they are correct. Once a computer has validated the transaction, it is added to the blockchain.Every block on the blockchain has a unique hash, as well as the unique hash of the block before it.When information on a block is edited, the block's hash code changes. However, the hash code on the block after it would not. The difference in block size makes it difficult to change information on the blockchain without notice.


Most blockchain platforms are open-source software, meaning that the code is available for anyone to see. Anyone can view the code for this project. This gives auditors the ability to review cryptocurrencies for security flaws. There is no one authoritative figure or group who controls the code for Bitcoin, and it can be edited at any time.Because the network can make changes and upgrades, anyone can suggest changes or upgrades to Bitcoin. If a majority of the network users agree that the new version of the code with the upgrade is sound and worthwhile, then Bitcoin can be updated.
