Bitcoin Scaling & Security

Scaling, Security & Applications: Bitcoin Developer Intermediate Dive into the next stage of Bitcoin development with this intermediate course in the Bitcoin+ Developer™ Specialization. Building on foundational scripting skills from Pathway A, you’ll explore how to scale Bitcoin applications and implement security best practices for real-world solutions. Learn how Layer 2 solutions like the Lightning Network enhance transaction speed and network efficiency, and examine practical use cases that bring Bitcoin to life in payments, bridging, and decentralized applications. Security is paramount - you’ll understand common threat models, apply safe scripting practices, and analyze vulnerabilities to safeguard your code. Hands-on exercises and mini-projects ensure you move from theory to practice, giving you the confidence to design secure, scalable Bitcoin workflows. By the end of this course, you’ll be equipped to implement robust Bitcoin applications and be fully prepared for the final pathway — integration, innovation, and capstone - leading toward the full Bitcoin+ Developer™ Certification. This course is essential for developers aiming to bridge foundational knowledge with applied skills in Bitcoin scaling, security, and real-world applications.
