Decentralization: Blockchain technology operates without a central authority or middlemen, which means that transactions are processed directly between participants without the need for intermediaries.\n\n2. Immutability: Once data is recorded on the blockchain, it cannot be altered or deleted. This ensures the integrity of the data and prevents fraud or tampering.\n\n3. Transparency: Blockchain operates on a public ledger, meaning that all transactions are visible to everyone involved in the network. This promotes transparency and accountability in financial transactions.\n\n4. Security: Blockchain uses cryptography to secure data and protect against unauthorized access. Each block contains a cryptographic hash of the previous block, creating a chain of blocks that is difficult to tamper with.\n\n5. Autonomy: Blockchain technology is autonomous, meaning that it operates independently of any government, institution, or individual. This allows for decentralized applications","a":"Transparency and traceability: The contents of each block are  publicly visible, allowing users to inspect the transaction history and verify the authenticity of the data."}]}],"pr":"5ed3e6ef1904ad99c4835e57c4f8f67545d9547ed2e9b519d6133346c73f0b49"}
