Basics of Blockchain

A Blockchain is a digital ledger in which transactions made are recorded chronologically and publicly and the transaction can be anything of value.


The blockchain concept explained in 6 steps in a simple way

  1. Someone requests a transaction
  2. The request is broadcasted to a P2P network consisting of nodes (computer/mobile devices)
  3. The network of nodes validate the transaction (validation can be for cryptocurrency, contracts, or any other information)
  4. The transaction creates a new block of data for the ledger
  5. The new block is added to the existing Blockchain and it is permanent and cannot be deleted
  6. The transaction is completed
