Aug 14, 2025 | The Proof of Work Space – Shai Wyborski Monero vs Qubic Audit | Quai Network X-Space AMA

In this highly anticipated community space, the Quai Network core founders, Dr. K and Jonathan, sit down with Shai Wyborski, a prominent core contributor to Kaspa, to dissect the ongoing security drama shaking the Proof-of-Work (PoW) ecosystem: Qubic’s uncooperative mining attack on Monero (XMR).The panel dives deep into the data behind the attack, discussing whether Qubic actually achieved a true 51% dominance or if they are leveraging selfish mining and network variance (around 37%-44% hash rate) to systematically orphan Monero blocks and compromise its transaction liveness with empty blocks.Shai Wyborski breaks down his preliminary findings and introduces his upcoming 3-part research series on the history of selfish mining, from Bitcoin's core vulnerabilities to the beautiful yet impractical design of FruitChains, and how it all connects to Quai's breakthrough consensus mechanisms.Key Highlights From This Episode:The Monero vs. Qubic Breakdown: An inside look at how Qubic is exploiting Monero's CPU-friendly, ASIC-resistant algorithm (RandomX) to execute deep 5-to-6 block reorgs using empty chains.The ASIC vs. CPU Decentralization Paradox: Shai argues why ASIC resistance can inherently become a long-term security threat due to the lack of hardware scarcity, leaving networks vulnerable to sudden hash rate shifts.Statistical Variance vs. Hard Truth: Dr. K and Jonathan explain why mining pool API stats can be misleading and how a 100-block sustained window is required to mathematically prove true 51% dominance.How WorkShares (PRS) Fixes This: A technical look at why Quai Network’s rapid intra-block hash rate sampling (sub-second sampling vs. Monero's 2-minute block time) reduces variance and makes sub-51% liveness attacks economically unviable.The Future of Sustainable PoW: Why relying on transaction velocity and throughput (low fees, high volume) is the only way to secure a fixed-supply blockchain once block subsidies decline.Exclusive Community Announcements:The Quai x Tangem Hardware Wallet Pre-order: The exclusive, limited-edition hardware wallet is officially live, and only 444 units remain!
