These Mentorship Spotlights highlight the work done by the Mentors and the Mentees as part of their program participation.

It not only let me understand the fundamentals of open source development but also develop a library to support multiple client-side solidity code for EVM-based blockchains for smart contract interoperability through interfaces. The project helped me a lot in implementing the theoretical knowledge learned in university in real-world projects. I am so glad that I got a very supportive mentor. Despite our timezones, he helped a lot in every aspect of the project. “ Mentor [image_with_animation image_url=”116338″ image_size=”full” animation_type=”entrance” animation=”Fade In” hover_animation=”none” alignment=”” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”] Kai Chen “I am honored to complete my second Hyperledger mentor tour. I am very happy to be able to share my own design concept with everyone. It may not be perfect, but it may bring some inspiration to others. I am very grateful to the mentee who participated in this project. He was able to find the flaws in the earlier design in his own practice and perfected the new design after our discussion. He learned the core principles of cross chain from it, and, at the same time, learned the application of transaction locking in the cross-chain scenario. The whole process is very beautiful. We really found joy in the  knowledge exchange brought about by open source. From this process, I also realized the fun of open source collaborative work. I hope to continue to participate in the future and witness the future of open source collaboration.” A special thanks to the Hyperledger member companies for funding this important program.
