Could you please elaborate on what a Bitcoin double spend is in simple terms? I've heard the phrase but I'm not entirely clear on its implications. As I understand, it relates to the potential misuse of Bitcoin, but I'm curious to know how someone might attempt such a transaction and why it's considered problematic. Specifically, how does it violate the fundamental principles of Bitcoin's decentralized ledger system, and what measures are in place to prevent or detect such attempts? Thank you for clarifying this aspect of 
cryptocurrency transactions.

    This is achieved by sending a duplicate copy of a transaction, aiming to make the duplicate appear legitimate.

    At its core, a Bitcoin double spend is a malicious act where an individual attempts to defraud the system.

    Unlike physical currency, digital currencies like Bitcoin exist solely in the digital realm.

    This makes them susceptible to duplication, allowing for double spends to occur.

    While doing so, the perpetrator retains the original transaction, creating a conflict in the ledger.
