  • High Security: Transactions are encrypted and verified by multiple nodes.
  • Reduced Fraud: No central authority means no single point of failure.
  • Lower Costs: Eliminates middlemen, reducing fees.
  • Faster Processing: Transactions settle in minutes, not days.

3. Steps to Use Blockchain for Secure Transactions

A. Choose a Blockchain Network
  • Public Blockchains: Bitcoin, Ethereum (ideal for transparency and decentralization).
