Scalability in Blockchain and Distributed Systems Foundations

Blockchain technology faces a critical challenge: maintaining security and decentralization while handling high transaction volumes. To build the next generation of decentralized applications, you must understand the underlying distributed systems that make them possible. This course takes you from the core concepts of distributed consensus to the advanced architectures used to scale modern blockchains, helping you transition from a basic understanding of blocks to a deep grasp of how to optimize network throughput. What you'll learn: - Understand the foundations of distributed computing, including the CAP theorem and Byzantine Fault Tolerance. - Analyze consensus mechanisms to identify performance bottlenecks and security trade-offs. - Explore modern scaling strategies such as sharding, sidechains, and Layer 2 rollups. - Identify common security vulnerabilities and learn how to mitigate risks in a distributed environment. - Examine modular blockchain architectures and the separation of data availability from execution. - Practice evaluating network trade-offs between speed, security, and decentralization. The material begins with essential terminology and the history of distributed systems before moving into practical scaling frameworks and contemporary architectural patterns. This course is designed for beginners and aspiring developers with no prior experience in distributed systems or advanced cryptography.
