   • Transparency: All transactions are recorded and visible to authorized participants, ensuring accountability and trust.
   • Immutability: Once recorded, transactions cannot be altered or deleted, providing a permanent and verifiable record.
   • Security: Cryptographic techniques and consensus mechanisms ensure the integrity and security of the data and transactions.
   • Scalability: Blockchains can handle high volumes of transactions through various consensus mechanisms and off-chain solutions.

3. Applications:

   Blockchain technology has a wide range of applications, including:

   • Cryptocurrency: Bitcoin, Ethereum, and other cryptocurrencies use blockchain to create a secure and decentralized monetary system.
   • Supply Chain Management: Blockchain can track the origin, movement, and ownership of goods, reducing fraud and increasing transparency.
   • Healthcare: Medical records can be securely stored and shared on the blockchain, improving patient privacy and efficiency.
   • Voting Systems: Blockchain-based voting platforms can ensure secure and verifiable elections with reduced risk of fraud.
