Could you elaborate on the concept of "Axelar Learn and Earn"? I'm interested in understanding how this program works, what kind of knowledge or skills it aims to impart, and what incentives or rewards participants might receive for their engagement. Is it a structured educational program, or a more informal learning opportunity? Are there any prerequisites for participation? Additionally, how does Axelar ensure the quality and relevance of the educational content offered? I'd appreciate any insights you can provide to help me gain a clearer understanding of this initiative.
