Blockchain is changing the way money moves. It offers a secure and transparent way to handle transactions. Unlike traditional banks, blockchain does not rely on a central authority. This makes financial transactions faster, cheaper, and safer.

This guide explains how blockchain works and how it is improving finance. It covers its benefits, challenges, and future impact on businesses and individuals.

What Is Blockchain?

Blockchain is a digital ledger that records transactions. It stores data in “blocks,” which are linked together. Once a block is added, it cannot be changed. This makes blockchain secure and reliable.

Key Features of Blockchain:

  • Decentralisation: No single authority controls it.
  • Transparency: Transactions are visible to everyone on the network.
  • Security: Data is encrypted and safe from hacking.
  • Immutability: Once recorded, transactions cannot be altered.

Types of Blockchain

Public Blockchains

  • Open to everyone.
  • Used by cryptocurrencies like Bitcoin and Ethereum.
  • Fully decentralised but slower.

Private Blockchains

  • Restricted to selected users.
  • Used by banks and businesses.
  • Faster and more private but less decentralised.

Consortium Blockchains

  • Controlled by multiple organisations.
  • Common in supply chain management and banking.
  • Offers both privacy and partial decentralisation.
