While you're celebrating $ETH's all-time high, the crypto world just witnessed a $6 billion network being dominated by a $300 million upstart. What happened: ➢ @_Qubic_ offered miners up to 3× @monero’s payouts. ➢ Massive miner shift → Qubic hit 52.72% hashrate (3 GH/s). ➢ Ran a “selfish mining” demo. ➢ Withdrew after showing it could dominate. ... Monero (XMR) ➠ privacy-first PoW coin mined mostly on CPUs. Qubic (QUBIC) ➠ AI + “useful proof-of-work” mining model. Qubic is a project focused on AI and "useful proof-of-work" (uPoW). Instead of just mining for rewards, Qubic uses mining power for AI tasks when it's not busy, and it mines other coins like Monero's $XMR to make money. They then sell the mined Monero to buy and "burn" (permanently remove) $QUBIC tokens, which can drive up QUBIC's price. Maybe more detailed on why Qubic attack affect Monero. Why did it happen? Higher payouts ⟶ Miners switch ⟶ Qubic > 51% ⟶ Selfish mining demo ⟶ Exposed decentralization risk Results: A 6-block reorg happened when Qubic mined 6 blocks in secret and dropped them all at once, replacing other miners’ blocks. No consensus takeover as it just part of experiment, but it showed how much power a single pool can have over the network. ... Now we can understand the implications of a 51% attack on the blockchain. It occurs through sophisticated strategies that lure miners, enabling attackers to dominate and control the hashrate. While Proof of Work (PoW) might be the most robust and secure economic model, its decentralization is only as strong as its miners. This situation illustrates how swiftly that balance can be disrupted through shift of incentives.
