The Lost Block: A Crypto EnigmaEthan Carter had spent years analyzing the blockchain, searching for anomalies. As a data scientist, he had seen it all—abandoned wallets, forgotten fortunes, and clever exploits. But nothing compared to what he discovered one evening: a block that shouldn’t exist.The MysteryWhile running an audit on old transactions, Ethan found Block #739274—a block that wasn’t in any official blockchain record. It contained a single transaction: a transfer of 50 BTC from an address that didn’t exist.His heart pounded. If this was real, it meant someone had figured out how to alter blockchain history. That was supposed to be impossible.The HuntEthan reached out to Ava Moreno, a cryptographic expert he trusted.“This block isn’t real,” Ethan told her. “But it’s there. I can see it in my node.”Ava frowned. “If someone has figured out how to rewrite blockchain history, they hold the ultimate power.”They traced the anomaly to an underground forum. A hacker named ‘Sable’ had posted about an experiment—rewriting past transactions without breaking consensus.
