The LKU, a utility core used as a payment method on the Rukyu platform, is co-exist within the platform, enabling the establishment of a healthy, cyclical system. The development of the platform will ultimately increase the utilization and value of the LKU, and in addition, the profits will also increase. It also breaks the boundaries between suppliers and consumers and pulls them to become partners who share the same goals. Therefore, all legal actions that occur in the Rukyu Project must be contributed to and participated in the cycle of the platform regardless of type.
