September 14 Block Monero underwent a reorganization that changed 18 network blocks and invalidated 118 previously confirmed transactions.
The essence of a reorg is when a competing clan of validators with greater influence overtakes others by removing orphaned blocks and returning unique transactions to the queue.
The 51% attack was first noticed by community members, and analysts called it the largest reorganization in history. MoneroEighteen consecutive blocks with heights between 3,499,659 and 3,499,676 were replaced, and 118 transactions were cancelled and pending reprocessing.
The attack was immediately suspected of being carried out by a competing project, Qubic, whose computing power on the network Monero has been dominant since August. Previously, Qubic representatives presented their threats and antics as a warning about the vulnerability of the network.
Following the incident, users were urged to send hashrate into smaller pools to weaken the larger operators.
