Key Features of Blockchain:

1. Decentralization: No central authority controls the data. Instead, it is managed by a network of participants.


2. Immutability: Once a block is added to the chain, its data cannot be altered without altering all subsequent blocks, which requires consensus from the majority of the network.


3. Transparency: Transactions are recorded on a public ledger, which can be viewed by all participants, depending on the type of blockchain (public or private).


4. Security: Blockchain uses cryptographic techniques to ensure the security and authenticity of the data.

Blockchain technology revolutionizes data management with its key features: decentralization, immutability, transparency, and security. This innovative approach ensures trust, efficiency, and integrity in various industries, from finance to healthcare. Embracing blockchain can lead to enhanced security, streamlined processes, and increased transparency in transactions.
