Theme: Understanding Modern Decentralized Application Architectures Sub topic: Designing for Fail-Safety and Fault Tolerance This session explores the architectural shift from centralized systems—which often suffer from single points of failure—to decentralized applications (DAPPs) that are inherently fault-tolerant and resilient by design. Using blockchain, smart contracts, and peer-to-peer networks, decentralized architectures distribute control, eliminate central dependencies, and automate trust. Key topics include the distinction between centralized, distributed, and decentralized models; how dApps function without traditional servers; the role of smart contracts in automating logic; and how decentralized storage and oracle networks solve real-world data and scalability challenges. The talk provides practical design patterns for achieving end-to-end resilience—from backend logic to frontend hosting—and introduces a new mindset where failure is expected, tolerated, and architected for.
