  Sure! Bitcoin prevents double spending through a decentralized network called blockchain. When a transaction is made, it is verified by multiple nodes in the network. These nodes compete to solve complex mathematical problems, and the first one to solve it adds the transaction to a block. Once the block is added to the blockchain, it becomes extremely difficult to alter or tamper with the transaction. This ensures that the same Bitcoin cannot be spent twice.

  Bitcoin uses a consensus mechanism called Proof of Work to prevent double spending. Miners use their computational power to solve mathematical puzzles, and the first one to solve it gets to add a new block to the blockchain. This process ensures that transactions are verified and recorded in a secure and transparent manner, making it nearly impossible to double spend Bitcoin.
