Why Do We Use Blockchain?

Blockchain is a distributed digital ledger of transactions. It changes the whole concept of the transaction now we don’t have any need for centralized authorities to verify our transactions, blockchain makes it decentralized and secure. The security is maintained by cryptographic processes performed by p2p users, through the process called Data mining Here are some important features given below:

  • Secure
  • Transparent
  • Tamper-proof
  • Peer-to-peer transaction

What is Blockchain?

A Blockchain is a digital ledger of transactions that is secure, immutable, and decentralized. It consists of a chain of blocks and each block contains a secure group of transactions of money, bitcoins, contracts, property, etc. without any need for third-party middle-man such as central authorities, banks, government, etc. Transactions are verified by a network of computers. Once a block of information is created in the chain, it can’t be changed or deleted. This makes the blockchain very secure and trustworthy. It is a software protocol, it never runs without the internet....
