Aug 13, 2025 | Tech AMA with Dr. K - Monero 51% Attack | X Space AMA| Quai Network

In this week's Technical AMA, the Quai Network core team dives deep into one of the most critical events unfolding in the crypto space: the ongoing liveness Attack on the Monero (XMR) network by Qubic via merge-mining.With roughly 25% of the network hash rate, Qubic has been executing deep chain reorganizations (reorgs) using empty blocks, causing massive uncertainty for transaction finality.Dr. K and the team break down how traditional Proof-of-Work (PoW) architectures are inherently vulnerable to these sub-51% attacks due to slow hash rate sampling, and explain exactly why Quai Network’s WorkShares (PRS) technology completely eliminates this threat.Key Highlights From This Episode:The Monero Attack Breakdown: How Qubic is exploiting Monero's consensus by mining private chains of empty blocks to compromise network liveness.The Sub-51% Vulnerability: Why linear blockchains like Bitcoin and Monero struggle with high variance in hash rate sampling, allowing a 25% miner to "get lucky" and disrupt the chain.The Quai Solution (WorkShares): How Quai’s 5-second block times and rapid 8-sample work shares accurately measure the mining population, making sub-51% attacks mathematically infeasible.Quai vs. Kaspa: Addressing Shai’s challenge regarding Quai's verifiable advantages over Kaspa, specifically focusing on L1 smart contract programmability and superior structured DAG anti-chains.MiCA Compliance & Future Listings: What the European Union’s MiCA approval means for Quai's regulatory positioning and upcoming global listings like Kraken.For more technical updates, deep dives, and articles, check out Quai Magazine.And if you enjoyed this episode, make sure to follow the podcast and leave a 5-star review!===============================Stay connected with Quai Network:Website: https://qu.ai/Docs: https://docs.qu.ai/learn/introductionX (Twitter): https://x.com/QuaiNetworkDiscord: https://discord.gg/quai===============================Stay connected with Quai Magazine:X (Twitter): https://x.com/QuaiMagazineTelegram: https://t.me/QuaiMagazineMedium: https://medium.com/@quaimagazineHearthis: https://hearthis.at/quaimagazine/Gravatar: https://gravatar.com/quaimagazineInstagram: https://www.instagram.com/quaimagazine/
