Security is Changing

Blockchain security has evolved far beyond smart contract bugs and basic consensus risks. Today’s defenders must secure multi-layer ecosystems, cross-chain bridges, off-chain infrastructure, and an entirely new frontier of AI-driven autonomous agents. This course is a comprehensive, forward-looking blockchain security program, designed for professionals who need to understand not only how attacks work but also why ecosystems break and how to design systems that survive real adversaries.

In-depth Content 

Access more than 170 lectures, and you will learn how to dissect attacks, model threat surfaces, secure decentralized systems, and defend against emerging risks created by AI, multi-agent systems, nation-state adversaries, MEV optimization engines, and cross-domain execution pathways.

Intermediate Level Course 

The internet is awash in beginner-level courses. This is meant to be an intermediate-level course that builds on basic blockchain security. If you have taken our basic blockchain security course or others, this course builds on that content to help you understand and work with modern blockchain attacks and AI as a hyperspeed attack vector.

About the course

This intermediate-level Blockchain Security course goes far beyond basic smart contract bugs to examine how modern Web3 systems actually fail in practice. You will learn to threat model the full blockchain stack, including wallets, dApps, consensus layers, Layer 2 systems, bridges, and off-chain infrastructure, using proven frameworks such as STRIDE, PASTA, OCTAVE, and trust boundary analysis. The course covers real-world attack classes including consensus manipulation, MEV and mempool abuse, economic exploits in DeFi, cross-chain and bridge failures, hybrid Web2/Web3 infrastructure risks, and AI-enhanced attack surfaces. You will also explore secure development and defensive engineering practices, DevSecOps for blockchain, audit workflows, runtime monitoring, and governance controls, alongside forward-looking topics such as AI agents, autonomous exploit pipelines, regulatory pressures, quantum-era cryptography, and national security considerations. Designed for blockchain engineers, security professionals, auditors, and risk practitioners who already understand the basics, this course builds the skills needed to analyze, defend, and design resilient blockchain systems in an increasingly adversarial and AI-accelerated environment.
