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 a block is added to the blockchain, its contents cannot be altered or deleted. This ensures that the history of transactions is permanent and tamper-proof.↵↵3. Transparency: The blockchain is a public ledger that records all transactions, making it easy to verify the authenticity and integrity of the data.↵↵4. Security: Blockchain technology uses cryptography to secure the network and protect sensitive information. Cryptographic algorithms encrypt the data, making it difficult for unauthorized parties to access or manipulate it.↵↵5. Peer-to-peer (P2P) networking: Blockchain networks rely on P2P technology to enable direct communication between participants without the need for a centralized server or","a":"Consensus mechanism: Participants (nodes) in the blockchain network need to reach consensus to validate and confirm transactions. The consensus mechanism ensures the  security and stability of the network and prevents unauthorized modifications to the blockchain."}]}],"pr":"0118476a932e330ef0239dd8e69e4dec60ed634a32e3ec47f3528cedfafb0f5d"}
