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 truly revolutionizes data management by offering decentralization, immutability, transparency, and security. Its innovative features provide a trustworthy and efficient way to record transactions. This makes blockchain a promising solution for various industries seeking to enhance data integrity and security.
