It is a unique identifier that ensures the security and integrity of the transaction. In the context of blockchain, Nonce is typically a random number generated by the sender of the transaction to prevent double-spending attacks. It is included in the transaction message and serves as an input for the blockchain network to process the transaction. The Nonce ensures that each transaction is unique and cannot be reversed or duplicated, thereby maintaining the overall security and credibility of the blockchain ecosystem.","a":"In blockchain technology, Nonce (Number used once) is a one-time digital number, which is a random number used to ensure the uniqueness and security of transactions in the blockchain network. The main role of Nonce is to prevent double-spending attacks and ensure the uniqueness of each transaction in the blockchain network. In blockchain systems such as Bitcoin, Nonce is usually used in the Proof of Work mechanism, where transactions are verified and new blocks are created by solving a complex mathematical problem. Each time a new block  is created, the Nonce changes, ensuring the order and linking between blocks."}]}],"pr":"a083ea169f54d46337f625daafd20b39afa87f263c9ea343c6ee32a3378decfb"}
