Qubic Controls 51% of Monero Hash Rate, Triggers Block Reorgs
TL;DR
During Epoch 173, Qubic reached peaks exceeding 51% of Monero’s hashrate, reorganizing six blocks and leaving 60 orphaned.
Mining generated approximately 750 XMR and 7 million XTM, converted into 62.2 billion QUBIC and distributed among Computors and miners.
Qubic ran three 24-hour marathons directing its full computing power at Monero, increasing profitability to nearly four times that of direct mining.
During Epoch 173, Qubic demonstrated temporary dominance over the Monero network, drawing attention from the crypto community.
Qubic Shows Its Strength Through Monero
At specific periods, the network surpassed 51% of Monero’s global hashrate, triggering the reorganization of six blocks and turning 60 blocks into orphans. In intervals of up to two hours, Qubic produced roughly 80% of the total network blocks, showcasing its processing power and growing influence within the XMR ecosystem.
In terms of profitability, the epoch highlighted a stark contrast between the two networks. Qubic mined about 750 XMR and 7 million XTM, generating a combined revenue estimated at $240,000. The mined tokens were converted into 62.2 billion QUBIC, fully distributed to Computors and miners with an approximate value of $200,000.
Additionally, 17.2 billion QUBIC, resulting from unsold XTM and Tari from the previous epoch, were burned at an average price of 3,200 QUBIC per billion, equivalent to around $55,000. The network reached a peak hashrate of 2.71 GH/s, representing 52% of Monero’s total hashrate, and mined 5,506 blocks during the epoch. Internal analysis shows Qubic was nearly four times more profitable than direct XMR mining.
Quantum Cryptography
The 51% experiment raised skepticism among experts, prompting the hiring of an independent specialist, Dr. Shai Wyborski, PhD in Quantum Cryptography, to verify the data. Preliminary findings indicate that while Qubic did not maintain absolute dominance throughout the epoch, there were one-hour intervals where it mined up to 80% of blocks, confirming the scale of its computing capacity.
The experiment was conducted through “marathons,” during which Qubic dedicated 100% of its mining power to Monero. Previously, the network split its time between mining and training its internal AI, AIGarth, a strategy that proved more profitable than direct mining.
During Epoch 173, three 24-hour marathons were completed, involving system adjustments and software reinforcements against DDoS attacks. The final marathon on August 12 coincided with periods when the hashrate exceeded the 51% threshold, currently under review to validate the experiment’s effectiveness and network impact.
This episode confirms that Qubic can direct its infrastructure toward strategic goals, providing not only returns for miners but also a functional laboratory to demonstrate advanced Useful Proof of Work applications on existing blockchains
