What Is Blockchain and How Does It Work?

Blockchain is a distributed ledger technology (DLT) that allows for secure, transparent, and tamper-proof transactions. It is best known as the underlying technology behind Bitcoin, but it has many other potential applications.

Blockchain works by storing data in blocks that are linked together in a chain. Each block contains a hash of the previous block, which makes it very difficult to tamper with the data without being detected.

To add a new transaction to the blockchain, it must be verified by a majority of the nodes on the network. Once a transaction is verified, it is added to the next block in the chain.

Advantages Of BlockChain Technology


Blockchain is very secure because it is difficult to tamper with the data without being detected.


 The blockchain is transparent because all transactions are publicly visible.


 The blockchain is tamper-proof because each block is linked to the previous block using a cryptographic hash.


 The blockchain is decentralized because it is not controlled by any single entity.



Blockchain can be used to create new financial products and services, such as decentralized exchanges and smart contracts.

Supply chain management: 

Blockchain can be used to track the movement of goods through a supply chain, ensuring transparency and traceability.


Blockchain can be used to store medical records and manage clinical trials.

Blockchain is still a relatively new technology, but it has the potential to have a major impact on many industries.
