Blockchain Protocol Engineers are the architects of the decentralised world. They design, develop, and maintain the core protocols that underpin blockchain networks, ensuring they are secure, efficient, and scalable. These engineers work on Layer 1 (L1) systems, which are the foundational layers of blockchain technology, and are crucial for the development of new features, consensus mechanisms, and security protocols. They are often found in scaleups, research-heavy startups, and the larger consultancies that are pushing the boundaries of blockchain technology.
