Securing the Blockchain: A New Approach to Smart Contract Vulnerability Detection

11.12.2025 by qfx

BugSweeper establishes a robust vulnerability detection system by transforming contract code into Function-Level Abstract Syntax Graphs (FLAGs)-augmented with control-flow and data-flow information-and subsequently analyzing these graphs with a two-stage Graph Neural Network to identify potential security flaws.

Researchers have developed a novel framework, BugSweeper, that leverages graph neural networks to pinpoint vulnerabilities within smart contract code with greater precision.

Fixing the Flaws in AI-Generated Images

10.12.2025 by qfx

The self-refining diffusion framework establishes a dual-phase training scheme-first building a foundational image generation capability, then iteratively enhancing quality by integrating flaw information from a mean flaw attention map ($mFAM$) into both forward and reverse processes, ensuring continuous refinement beyond initial baselines.

Researchers are using explainable AI to pinpoint and correct imperfections in images created by diffusion models, leading to more realistic and refined results.
