What are Layer 2 solutions?

Layer 2 solutions like the Lightning Network help Bitcoin scale faster, enabling quicker transactions and lower fees.

Are there practical projects?

Yes. You’ll design mini Layer 2 applications and evaluate security considerations for real-world Bitcoin use cases.

How is security addressed?

Learn safe scripting patterns, threat models, and best practices to protect Bitcoin applications against common vulnerabilities.

Will this help me build real applications?

Absolutely. Pathway B emphasizes applying knowledge to create functional, secure, and scalable Bitcoin solutions.

How are assessments structured?

Quizzes after each module and a mini-project/case study will test your Layer 2 and security knowledge.

What comes after this pathway?

You’ll progress to Pathway C for integration, innovation, and the capstone project, completing the full Bitcoin+ Developer™ Specialization.

Will I get a certificate here?

No. Certification is granted only after completing all three pathways and passing the unified proctored exam.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

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.

This module introduces the overall certification structure and explains how the learning experience is organized throughout the course. To support different learning preferences, the content is offered in multiple formats, including Videos, eBooks, Audiobooks, and Podcasts. Each format covers the same key concepts, giving you the flexibility to learn in the way that works best for you. You can choose any format based on your preferred learning style and move through the course at your own pace.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
