Have you ever been groping in the ocean of Web3 knowledge, reading countless tutorials, white papers and videos, but still feel that you only know the basics? Have you ever longed for a truly systematic course with a clear technical perspective and taught by first-line developers to help you understand the underlying logic of blockchain? Then you must not miss PBA-X, the flagship course founded by Gavin Wood and officially launched by Polkadot Blockchain Academy .
PBA-X (Polkadot Blockchain Academy eXplore) is a key online project offered by PBA, designed for those who want to grow from a Web3 novice to a "chain expert". It is carefully built by the Parity core team, does not require a programming background, and takes into account both systematicity and flexibility. With only about 6 hours of investment per week, you can fully master the Polkadot architecture and blockchain principles . In the past two sessions, more than 3,000 developers, operators, researchers, college students and entrepreneurs from more than 50 countries around the world have participated in it, and it has been widely praised.

📖 What do you learn in PBA-X?
PBA-X does not only teach you "how to do it", but also helps you to truly understand "why". The course is based on 6 core modules, helping you to move from the basic concepts of blockchain to the ability to understand and participate in the design of the underlying architecture:
Cryptography: The foundation of security
Understand key generation, digital signatures, symmetric/asymmetric encryption, master core structures such as Merkle trees, and lay a solid technical foundation for the "trust mechanism" of the Web3 world.
Economics: Understanding the drivers of on-chain behavior
Learn about supply and demand logic, game theory and market mechanisms, understand why token design is so important, and how to achieve consensus and governance through incentive mechanisms in decentralized networks.
Blockchain Basics: From Bitcoin to Today
A comprehensive review of the development path of blockchain, focusing on state machines, consensus mechanisms, forks, P2P networks and smart contracts, so that you can truly understand how the "chain" works.
Governance Mechanism: Institutional Design for a Decentralized Society
Analyze the evolution and challenges of different governance models, focusing on Polkadot's OpenGov system to help you grasp the practical logic of on-chain democratic decision-making and governance upgrades.
Governance Mechanism: Institutional Design for a Decentralized Society
Learn core components such as Substrate, FRAME, XCM, and technical details such as WASM virtual machine and Scale Codec to build scalable and interoperable blockchain applications on Polkadot.
Polkadot Architecture: A Real-World Scenario for Cross-Chain Collaboration
Gain a deep understanding of the responsibilities of relay chains, parachains, validators, and collectors, master the multiple roles of DOT in staking, governance, and security, and lay the foundation for advanced content such as asynchronous support.
📌 Who is suitable to apply?
Want to switch to Web3 but don’t know where to start?
If you want to understand the underlying logic of blockchain and lay the foundation for entrepreneurship
If you are interested in Polkadot/Substrate development
If you want to enter PBA Campus or even a world-renowned Web3 company
Whether you have a background in product, development, design, operation, or finance, PBA-X is the "first learning method" to enter Web3.
Mentor lineup
Gavin Wood : Co-founder of Ethereum, founder of Polkadot, and originator of the Web3 concept
Shawn Tabrizi : Parity core developer, Substrate architecture expert
Kian Paimani : XCM and cross-chain protocol designer, technical evangelist
Parity & W3F front-line engineering team : full participation in courses, answering questions, and compiling materials
You’ll hear blockchain designers themselves speak their original ideas, not “paraphrased versions”.
💬 FAQ before registration
Q: Can I learn it without a technical background?
A: Yes. The course is designed to be "technology-friendly". The key technical principles are explained in a simple and easy-to-understand way. Some optional programming content is suitable for those who have a basic understanding to deepen their understanding.
Q: Is there a certificate at the end of the course?
A: Yes. You will receive a certificate of completion issued by PBA, which has been considered a plus by many Web3 projects.
Q: Is there any information in Chinese?
A: The main course is in English. Some communities will organize Chinese notes, study groups and synchronized materials. We recommend joining the Polkadot Chinese community for support.
Q: What opportunities will there be after completing the course?
A: Those with excellent academic performance will be recommended to enter PBA Campus (face-to-face further studies), PBA Fellowship program, or be recommended to internship/job opportunities in the Polkadot ecosystem.
