Bitcoin Transaction & Network Security

Advance your expertise with the second track in the Securing the Assets: Bitcoin Security specialization. After building your foundational knowledge in Track 1, this stage takes you deep into the mechanics of transaction and network protection — the heart of Bitcoin’s security model. You’ll learn how to secure Bitcoin scripts, defend network protocols, and protect wallets from key theft and malware attacks. Through interactive labs and real-world exercises using Bitcoin Core, Electrum, and Blockchair, you’ll analyze vulnerabilities, simulate attacks, and implement countermeasures that keep assets safe. Each module combines conceptual learning with hands-on tasks, quizzes, and case studies to help you master practical defenses. By the end of this track, you’ll be able to design and test secure transaction flows and network infrastructures - and be ready to move to Track 3: Threats, Strategy & Innovation, the final step toward your Bitcoin+ Security™ certification.
