Securing Sparse Matrix Math in the Cloud
![Homomorphic encryption of sparse matrix-vector multiplication (SpMV) in compressed sparse row (CSR) format introduces substantial computational overhead, as each element-wise product, while achievable, necessitates a costly homomorphic rotation and multiplication for subsequent aggregation-a limitation stemming from the inability to efficiently combine encrypted partial results without incurring these operations on every addition required to construct the final encrypted vector sum [latex] \sum_{j=1}^{n} A_{ij} x_j [/latex].](https://arxiv.org/html/2603.04742v1/2603.04742v1/x1.png)
A new approach to privacy-preserving sparse matrix-vector multiplication unlocks significant performance gains using homomorphic encryption.

Sky’s USDS Flies High as Stablecoin Empire Hits $313 Billion
The fiat-pegged token economy, a grand ballet of dollar clones, expanded 0.88% this week as $2.742 billion flowed in, per the sacred texts of defillama.com. Tether ( USDT), that old titan of the trade, still hoards $183.93 billion in its vaults, growing a paltry 0.16% while its dominance slips below 60%-a humiliation! Its rivals, ever the comedians, now claim 58.76% of the $313.002 billion pie, as if the U.S. dollar itself were a stage for farce.
Fortifying Homomorphic Encryption Against Known-Plaintext Attacks
A new modification to the Fully Homomorphic Modified Rivest Scheme enhances security while preserving the ability to compute on encrypted data.
10 Open-World Games That Totally Reinvent Themselves Halfway Through
Many open-world games offer a huge amount of exploration, but simply having a lot to do doesn’t always make them engaging. While they often include numerous side quests and completionist goals, the core gameplay can sometimes feel repetitive.
Building Resilient AI: A New Loss Function for Error-Tolerant Neural Networks
A novel training approach enhances the robustness of quantized neural networks against bit errors, paving the way for more reliable deployment in resource-constrained environments.
Kalshi and Polymarket: $20 Billion Dreams or Financial Absurdity?
Prediction markets, where people trade contracts about whether Biden will win or if it’ll rain next Tuesday, have become the new frontier for Kalshi and Polymarket. Their fundraising dreams? A $20 billion valuation each, because why not? The WSJ says it’s “early-stage,” which means it’s probably a lie wrapped in a PowerPoint.
AI Grading Gets a Reality Check
/|\text{Baseline}-\text{Human}|[/latex]- achieved by large language models on the ASAP-SAS dataset; a transformer ensemble (point A, Ormerod, 2022) and a fine-tuned GPT ensemble (point B, Ormerod & Kwako, 2024) progressively surpass earlier baselines-with a subsequent GPT-4 implementation (point C, Jiang & Bosch, 2024) projected to reach a normalized score of -1.52-indicating a substantial, ongoing refinement in automated assessment capabilities.](https://arxiv.org/html/2603.04820v1/2603.04820v1/x1.png)
A comprehensive analysis reveals that current artificial intelligence systems struggle to accurately assess short-answer responses, exposing fundamental limitations in their understanding of meaning.
PI Network BOOM! Crypto Gurus Mic Drop Over $0.28 Failing Fable!
In the feverish world of digital moneys, a quiet rise in volume during a quiet climb in price is like a mischievous cat alerting you that something sweet is secreted on the window sill. According to CryptoQuant’s tiny, invisible map of bubbling trades, PI/USD has been politely inching upward, and yet, the shush of “Breakout!” remains a polite suggestion rather than a shouted proclamation. “Oh, you’re thinking ‘Uh-oh,’” says the indicator, as all of a sudden, its volume mood swings into a guilty neutral.
The 15 Best Indie Strategy Games To Play In 2026
Thronefall, a minimalist strategy and tower defense game, launched in late 2024 after a short initial release period. It simplifies the genre to its core elements, which is a major strength. Players command a single rider, a monarch on horseback, managing their kingdom’s defenses and economy by day and battling waves of enemies by night. Each session lasts only 10-15 minutes, creating a fast-paced and rewarding experience. Players quickly become engrossed in the gameplay, and it’s earned an impressive 96% positive rating on Steam, based on over 20,000 reviews.
