Polkadot Blockchain Academy has announced the launch of The JAM Course, an educational initiative aimed at introducing top industry developers to Polkadot's latest technological advancements.
Introduction to The JAM Course
According to a blog post on February 10, the academy revealed that the program is set to begin in December 2025. The course will provide hands-on training in the Join-Accumulate Machine (JAM), a new architectural layer designed to enhance Polkadot's capabilities.
Technological Capabilities of JAM
JAM is positioned as a successor to the relay chain, enabling permissionless code execution, supporting Solidity smart contracts, and integrating roll-up outputs. This advancement allows developers to process computations off-chain before transmitting them to JAM, eliminating the need to choose between building appchains or smart contracts.
Educational Features of the Course
The course will provide participants with an in-depth understanding of JAM's core functions—Refine, Accumulate, and OnTransfer—while covering key tools like the Polkadot Virtual Machine and Polkadot API. Designed for advanced Web3 developers, The JAM Course builds on the foundation set by the PBA Campus and the JAM Tour, offering an intensive, practical learning experience with expert-led tutorials and hands-on coding sessions.
Polkadot Blockchain Academy CEO Pauline Cohen Vorms emphasized the transformative potential of JAM as a gateway for developers eager to explore the future of blockchain interoperability. The course continues the academy's mission to prepare developers for the decentralized future.
