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.

Impressive key features! Blockchain technology truly revolutionizes the way we handle data, ensuring security, transparency, and decentralization. Exciting to see how it's transforming various industries! 🌐🔒
