The Yohaku project promotes community contribution activities by utilizing decentralized technologies such as NFTs and blockchain. This allows for the fair evaluation of regional contributions and establishes a system that can be inherited by future generations. By applying these technologies, the project not only encourages local involvement but also offers a scalable model that can be adapted by other regions. This contributes to the growth of the OSS ecosystem by providing a reusable, open-source solution that can be expanded to tackle similar issues in different areas. The plan to open-source the project will enable further development and innovation within the ecosystem.
