Decentralization: Blockchain technology relies on a distributed network of computers to store and process data, which means that there is no single point of failure or control. This eliminates the need for a central authority or middleman, making the system more secure and transparent.\n\n2. Immutability: Once a block is added to the blockchain, it cannot be altered or deleted. This is because each block contains a cryptographic hash of the previous block, which prevents any changes from being made without altering the entire chain. This feature ensures that the data stored on the blockchain is permanent and tamper-proof.\n\n3. Transparency: Thanks to the decentralized nature of blockchain, all transactions are publicly accessible. This means that anyone can view the contents of a blockchain and verify the authenticity of transactions. This promotes transparency and accountability in the system.\n\n4.
