最新报道:Qubic, led by former IOTA co-founder Sergey Ivancheglo, claims to have secured over 51% of Monero's global hashrate, potentially enabling block reorganization, transaction censorship, and double-spend attempts on the privacy-focused blockchain. Ivancheglo framed it as a stress test, but the announcement sparked debate among developers. Monero's XMR dropped 6.65% amid concerns, while experts like Ledger CTO Charles Guillemet warned of a possible 51% attack. Qubic's "useful proof-of-work" model converts XMR rewards into USDT to buy and burn QUBIC tokens, driving its hashrate share from under 2% to over 25% since mid-May.
