Aug 15, 2025 | Quai Friday – All About Cold Storage with Tangem Wallet | Quai Network X-Space AMA

Fri, 29 May 2026 09:16:01 GMT

In this special "Quai Friday" episode, the Quai Network core team sits down with David from Tangem to celebrate the launch of the exclusive, limited-edition Quai-branded Tangem hardware wallets. David shares his insane personal journey of attempting to physically destroy Tangem cards (spoiler: 10-ton forklifters and blowtorches failed) and highlights the engineering marvel behind their 25-year warranty and battery-less design.

The conversation dives deep into optimal crypto security (OPSEC) and explains why removing traditional seed phrases eliminates the biggest modern vulnerability: human error and social engineering scams. Additionally, the teams talk about the revolutionary Tangem Ring (wearable cold storage), decentralized application (dApp) interaction via WalletConnect, and give an exclusive sneak peek into Tangem Pay —a massive upcoming integration with Visa allowing direct, middleman-free crypto spending at real-world terminals.

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

Fri, 29 May 2026 04:40:28 GMT

In this highly anticipated community space, the Quai Network core founders, Dr. K and Jonathan, sit down with Shai (Jack), 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 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! Secure yours now via our pinned links.

Upcoming Listings & Roadmaps: Massive ecosystem updates are coming throughout August and early September, including centralized exchanges (CEXs), decentralized exchanges (DEXs), bridges, and the highly anticipated Kraken roadmap progress.

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

Thu, 28 May 2026 01:03:24 GMT

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.
