anchored·FBZiXt…uMqFSummary
Qubic is a layer-1 blockchain project founded by IOTA co-founder Sergey Ivancheglo ('Come-from-Beyond'). On October 18, 2026, Qubic's validators (Computors) froze the network after an attacker exploited weakly generated wallet seeds to drain roughly $1.3-1.4 million in QU tokens from over 1,400 wallets; the chain remained halted as of the most recent reporting, pending a validator vote on restitution. The project was already a subject of controversy in 2025 over disputed claims that its mining pool had seized majority control of the Monero network's hashrate.
