Korean messaging firm Kakao launches testnet for proprietary blockchain

South Korean messaging giant Kakao is launching a testnet of its proprietary blockchain platform called Klaytn, local news outlet The Korea Herald has reported.

The move was announced today by Kakao's blockchain subsidiary GroundX, which said that with Klaytn, the company wanted to build a blockchain platform that would allow end users to experience blockchain technology in a seamless way. In order to achieve this, the company focused on user and developer experience.

“The popularization of blockchain requires providing a practical blockchain service for mass adoption thereby validating the value and utility of blockchain technology,” GroundX’s chief executive officer Jason Han said in a statement, as quoted by The Korea Herald. “To achieve this, Ground X has designed Klaytn that can provide an easy and friendly environment for end users, service providers and developers all at the same time,” he added.

GroundX also published a white paper, detailing its technical architecture and features. The document reveals that Klaytn uses a hybrid trust model, aimed at utilising the strengths of both private and public networks. The model employs a group of permissioned ‘Consensus nodes’ to run consensus algorithms on a private network and a permissionless, public network of ‘Ranger nodes’ to audit the blocks generated on the private network. GroundX believes that this approach would allow for the private network to have the security and transparency of a public blockchain “without sacrificing performance and reliability”.

The company claims that the platform is able to support 1500 transactions per second. The increased focus on user experience has led to the company’s decision to remove some of the standard features other blockchain platforms, such as wallets, private keys and cryptograph addresses. At the same time, Klaytn features tutorials and toolkits aimed at aiding developers of decentralised apps.

Klaytn’s testnet is currently available to about 10 partners in Korea and around the world, but interested parties can sign up for access on the platform’s website. Klaytn is expected to have its mainnet launch during the first quarter of next year.
