Partnership with Rebit AI

REBIT AI is a company that has been a 15-year solution partner to Samsung Electronics which provided embedded keyboard solutions to some of Samsung’s Galaxy series. With this technology, REBIT AI is prepared a crypto rewarding keyboard DApp.

Through the partnership with Samsung Electronics REBIT AI’s keyboard has finished testing for all languages, which makes it one of the only 4 keyboard applications that can provide such language coverage in the world. It will provide AI-based word completion and suggestion as Galaxy smartphone keyboards do. Furthermore, the DApp will utilize AI-based big data analytics and recommendation technology, which has been developed with Samsung Electronics but not used in its phones, for AD targeting and big data services. REBIT AI has already created a business model based on its big data competencies and is in steps of advancing it.

As such, top Korean companies like KT(Telecom), ActozSoft, Netmarble, global Ad platform YeahMobi, and MotherBrain have already partnered with REBIT AI and is currently expanding its partnerships also into India and Japan.

REBIT AI CEO Donjun Shin is upset about seeing the low utilization of unstructured big data and therefore has great expectations for its crypto rewarding keyboard business.

We are very happy to have REBIT AI as a member of QuarkChain Ecosystem

Staking also became a topic of discussion. Anthurine discussed the topic of “Benefit & Equity- The Rising of Staking Economic” and commented about the benefits of staking, capital security and how to attract the participators. Anthurine Xiang believes that “Staking” can be understood as pledging. However, staking also has the meaning of stock equity and earnings. Staking emphasizes participation. We encourage people to participate in community ecological development and become part of it, rather than simply gaining benefits by investing tokens in nodes. The meaning of staking is to encourage people to participate in community ecology.
