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.
