BeInCrypto
A 13-block reorganization on the Litecoin network, triggered by a zero-day exploit, has sparked concerns regarding blockchain immutability and transaction finality.Summary
The Litecoin network recently executed an emergency 13-block reorganization to reverse invalid transactions caused by a zero-day exploit in its MWEB privacy feature. The attack succeeded because many nodes were running unpatched software, allowing conflicting consensus rules to emerge. While developers have patched the vulnerability, the incident has reignited concerns about the reliability of blockchain finality and the security risks posed by uncoordinated network updates.
