An applicability assessment of fully homomorphic encryption (FHE) in DeFi private transactions evaluates 12 use cases across lending, exchanges, and derivatives. Results classify 5 cases as "immediately viable" (e.g., encrypted KYC), 4 as "prototype-ready" (e.g., private AMMs), and 3 as "conceptual" (e.g., real-time encrypted analytics). Key barriers include 100-1000x computation overhead versus plaintext processing and limited cryptographic library support.

Fluid Dynamics Model and Congestion Analysis for Waiting Times in Liquid Staking Exit Queues This paper presents a fluid dynamics model to analyze waiting times in liquid staking exit queues and assess congestion. By simulating queue dynamics under varying conditions, we identify bottlenecks and propose solutions to optimize exit processes, enhancing staking liquidity and user experience.

Network propagation delays create arbitrage windows in flash loans by causing information asymmetry across nodes. A 5-second delay between blockchain updates can result in 2% price discrepancies, exploitable for profit. Arbitrageurs use low-latency nodes and geographically distributed servers to minimize delays. However, rising network efficiency and consensus speed (e.g., Ethereum 2.0) reduce these opportunities. Data shows that arbitrage profits have declined by 60% since 2021 due to faster propagation. Future protocols may incorporate predictive modeling to anticipate delays, but scalability improvements will likely erode traditional arbitrage advantages in decentralized finance (DeFi).
