Klaytn APIs | Querying Klaytn Blockchain​

Klaytn is a South Korean blockchain platform that made a buzz when reports emerged that Samsung would integrate Klaytn in their flagship product, Galaxy note 10 and market them as “KlaytnPhone”. Klaytn is a service-centric blockchain platform developed by Ground X, the blockchain subsidiary of South Korea’s no one mobile platform, Kakao.

Klaytn is EVM compatible. It adopts a trust model of private consensus with the public disclosure, where a smaller group of consensus nodes (CNs) executes BFT consensus in a private network while surrounded by a larger public network of permissionless endpoint nodes (ENs) openly accessing (and where necessary, verifying) block generation results.

The image below shows the companies that run Klaytn’s consensus nodes.
