Can a bitcoin transaction be backtracked?
Could you elaborate on the possibility of reversing a Bitcoin transaction? Is there a mechanism in the blockchain system that allows for the retraction of funds once they've been sent? I've heard about the immutability of the blockchain, but does that mean a Bitcoin transaction is truly irreversible? Are there any exceptions to this rule, or is there a way for a user to potentially cancel a transaction in case of an error or fraud? Understanding the finality of Bitcoin transactions is crucial for investors and users alike, so I'd appreciate a detailed explanation of this matter.
