Blockchain technology is referred to as distributed ledger which keeps track of all the data exchanges. Here, data exchange is also known as the transaction.

Blockchain technology verifies each transaction using the distributed system. Once a transaction is verified and added to the blockchain, it is immutable.


As the blockchain technology uses a distributed system, copies of the ledger are stored in different locations. Hence, it is difficult to destroy each copy present in each location. Blockchain uses peer to peer network topology.

Advantages of Blockchain Technology:

  • Users have control over all transactions and information
  • Data stored using blockchain technology is available, consistent, complete and accurate
  • As distributed system architecture is used for blockchain, it does have single point failure and information is reliable and safe from malicious attacks
  • As protocols used in blockchain removes the need of the third-party app for verification of the transaction, users can trust this
  • Changes made to blockchain are transparent and all the transactions added to the blockchain cannot be altered.
  • As single and distributed ledger is used in Blockchain, there is no complication of creating and managing multiple ledgers
  • Transactions time can be reduced using blockchain and are available 24/7
