Decentralization: Blockchain technology operates without a central authority or middlemen, which means that transactions are processed directly between participants without the need for intermediaries.↵↵2. Immutability: Once information is recorded on a blockchain, it cannot be altered or deleted. This is because each block in a blockchain contains a cryptographic hash of the previous block, creating a chain of blocks that are linked together. Therefore, changing a single block would require altering all the subsequent blocks in the chain, which is virtually impossible.↵↵3. Transparency: The contents of each block in a blockchain are publicly accessible, which means that anyone can view the details of a transaction. However, the identities of the parties involved in a transaction are usually kept anonymous, protecting their privacy.↵↵4. Security: Blockchain technology uses cryptography to secure the integrity of the network and protect against unauthorized access.
