What is Klaytn?
Klaytn is an enterprise-grade, service-centric blockchain platform with the mission to bring user-friendly blockchain experience to the masses. Klaytn strives to become a blockchain platform that not only empowers global businesses and users to easily access and utilize blockchain technology, but also enables massive-scale applications and services to benefit from a higher degree of the platform's transparency, security, and trust. In order to lower the existing hurdles of the nascent technology and to accelerate the global market's embracement of blockchain, Klaytn achieves a number of challenges including making the developer experience (DX) intuitive and productive for developer communities by providing useful features and toolsets; offering a seamless user experience (UX) indistinguishable from legacy apps and services by effectively providing the means to remove friction as well as complexities throughout the users' journey; building a blockchain platform committed to service and performance without compromising high-degree of transparency and security; and thereby effectively resolving the chasm existing in this current blockchain scene to bring true global blockchain mass adoption.
What is BApp?
BApp (Blockchain Application) embodies Klaytn's philosophy and approach towards driving blockchain mass adoption. While "decentralization" is a respectable concept, we argue that it is rather a means, not an end for blockchain technology. We are thus committed to the belief that "decentralize everything" may not be the right approach towards bringing true enterprise-driven use cases to the current blockchain market. Therefore, we decided to adopt the word "BApp". We believe that a blockchain service need not be wholly or fully decentralized, as long as it uses characteristics of blockchain for significant purposes to improve its existing features.
What is Klaytn Horizon?
Klaytn Horizon invites developers from all around the world to build various BApps on Klaytn in a combined effort to bring blockchain mass adoption to fruition. Feel free to build a BApp to serve an industry of your choice, ranging from contents to entertainment, healthcare, finance, commerce, payment, lifestyle, and technology, etc. There is no limit to what you can build. There is no limit to what you can innovate!
What makes Klaytn Horizon special and different from other competitions?
Klaytn Horizon is the first of its kind to engage with developers from all over the world to build real-life applications on blockchain. The focus of Klaytn Horizon will far transcend simply building a BApp on Klaytn. Backed by Kakao Corporation, a mobile messenger and lifestyle application company owning 97% of South Korea's mobile messenger market, Klaytn aims at leveraging the significant traffic of Kakao’s existing 50 million active users for BApps built and operated on Klaytn. Moreover, Klaytn intends to succeed Kakao Corporation's multiple years of service operating experience as the top mobile messenger ecosystem in the market to bring truly user-friendly and intuitive services for end users. We sincerely invite all like-minded projects to join us for Klaytn Horizon.
Where should I go for technical docs?
All necessary technical documents can be found at Klaytn Docs There will be an AMA session with Klaytn tech team during the competition period. Please stay tuned with our official twitter for the latest news.
How can I reach Klaytn during Klaytn Horizon if I have further questions?
We will be hosting two online AMA (Ask Me Anything) sessions; stay tuned for the specific schedule and dates for the AMA via the Klaytn Horizon website. Please note that there may be more or less than two AMA sessions based on circumstances. Any changes or updates regarding the AMA sessions will be notified via the Klaytn Horizon website and Klaytn’s official social medias. For any inquiries, please contact
When can I receive the prize if my project is selected as an award-winning BApp?
There will be an intentional time difference between the announcement of award winning BApps and the provision of the corresponding prize. As a platform highly valuing real use cases and stable services, Klaytn decided to impose a time difference to ensure that BApps participating Klaytn Horizon responsibly operate services for a proven time period. The prize is expected to be delivered to all award-winning projects by Q1 of 2020.
Is it required to migrate my BApp onto Klaytn mainnet in order to participate in Klaytn Horizon?
Yes, please start building your project on the Baobab public testnet and make sure to migrate your BApp smart contracts onto the Klaytn mainnet once the mainnet is launched. We define "migration" as re-issuance of your project's existing smart contracts on Baobab onto the Klaytn mainnet. The launch of Klaytn Mainnet will be announced via Klaytn’s official website and social media channels.
Can I develop a BApp that does not use smart contracts?
Yes, your project does not necessarily have to use smart contracts to be qualified as a contestant for Klaytn Horizon. Simply using KLAY as a means of value transfer or payment alone qualifies projects as candidate BApps for Klaytn Horizon.
