Enrollment for the New 8th Substrate Advanced Course Now Open! Train to Become a Core Technical Talent in Blockchain Project Development!

In blockchain development, tedious and time-consuming technical details, such as P2P transaction propagation and cryptographic primitive writing, often slow down project progress and limit developers’ creative space. For teams aiming for rapid delivery, this inefficient development approach presents a significant challenge. The advantage of Substrate lies in providing ready-made modules and tools, helping developers break free from the constraints of underlying details, focus on business logic innovation, and accelerate the launch of blockchain solutions.

Substrate is an open-source, battle-tested Rust framework for building future-oriented blockchains optimized for most use cases — built by developers for developers. By offering pre-built modules and a flexible development framework, Substrate eliminates the burden of foundational technical details for developers, significantly broadening the scope and potential of blockchain design. This not only improves development efficiency but also opens up new possibilities for blockchain innovation, allowing developers to focus more on advancing cutting-edge technologies and applications in the industry.

Mastering Substrate not only equips you with the ability to quickly build and deploy blockchain applications but also places you at the forefront of blockchain technology, giving you a stronger voice in the industry. For this purpose, OneBlock+ and Polkadot have jointly launched the 8th edition of the “Advanced Substrate Development and Project Practice” course. Through this course, you will deeply learn the core technologies of Substrate, master cutting-edge development techniques, and hone your skills through practice. Whether you aim to make a breakthrough in the blockchain field or aspire to stand out in this emerging industry, this course will be a solid step toward your success.
