  The Bitcoin community has implemented a consensus mechanism called Proof of Work (PoW) to prevent double spending. Miners compete to solve complex mathematical puzzles, and the first one to find a solution gets to add a new block to the blockchain. This decentralized process ensures that transactions are verified and recorded in a secure and tamper-proof manner.

  To further enhance security, Bitcoin uses a decentralized network of nodes that validate and propagate transactions. Each node maintains a copy of the blockchain and verifies the authenticity of transactions. If a double spending attempt is detected, the nodes will reject the transaction, preventing it from being added to the blockchain.

  In addition to the measures mentioned above, the Bitcoin community has also introduced the concept of confirmations. When a transaction is included in a block, it is considered to have one confirmation. As more blocks are added to the blockchain, the number of confirmations increases, making it increasingly difficult to reverse or double spend a transaction. Typically, six confirmations are considered sufficient to ensure the transaction's finality.
