  The Bitcoin system reviews the authenticity of transactions through a process called mining. Miners use powerful computers to solve complex mathematical problems, which helps secure the network and validate transactions. Once a miner successfully solves a problem, they add a new block to the blockchain, which contains a record of all transactions. This block is then verified by other nodes in the network, ensuring that the transactions within it are valid and authentic.

  When a transaction is initiated in the Bitcoin system, it is broadcasted to all nodes in the network. These nodes then verify the transaction by checking if the sender has sufficient funds and if the transaction follows the rules of the Bitcoin protocol. If the transaction is deemed valid, it is included in a block and added to the blockchain. The decentralized nature of the Bitcoin system ensures that multiple nodes review and validate transactions, making it difficult for fraudulent transactions to be accepted.
