Slow Mist Cosine: 51% Attack on Monero Succeeds, Qubic Mining Pool Can Rewrite Blockchain

On August 12, the founder of SlowMist, Cosine, said that the 51% attack against Monero appears to have been successful, and the Qubic mining pool can now theoretically rewrite the blockchain to achieve double payment and review any transactions. The attack is expensive, and it is uncertain what the economic benefits of the attacker will be. Relevant platforms are advised to be aware of possible threats and stay tuned.
Ledger CTO Charles Guillemet tweeted that Monero appears to be suffering a successful 51% attack. The Qubic mining pool has been accumulating computing power for months and now controls most of the network's computing power. A major chain reorganization was detected this morning. With its current computing power, Qubic can rewrite the blockchain, implement double payments, and review any transactions. The cost of sustaining this attack is estimated to be as high as $75 million per day.
