The Klaytn blockchain from the fold of South Korean messaging app giant Kakao has just gone live.
Kakao's blockchain arm Ground X announced the mainnet launch Thursday in an emailed press release, saying that Klaytn aimed to bring about mass adoption of blockchain services and to "substantiate the value and utility of blockchain technology."
The firm touts the network as having a speedy response time on the level of legacy web services, based on the feedback from the partners via a public testnet trial announced last October. Stability has been verified with different security companies using "high-intensity" testing, the firm said, while blind testing for developers and users helped Ground X improve the Klaytn user experience.
Ground X has also announced that nine blockchain projects – including HintChain, a blockchain-based food data marketplace; Antube, a video snippet entertainment service; and Pibble, which rewards users in cryptocurrency for all their social media activities – are to be successively released on Klaytn by the beginning of July. Additionally, a number of blockchain-powered game services developed by three "major" game studios are to join Klaytn.
According to its white paper, the Klaytn blockchain takes a hybrid approach that adopts the concepts of consensus nodes (CNs) and ranger nodes (RNs) to achieve both scalability and transparency.
CNs are invited partners on the network that together form a private blockchain to batch and confirm transactions by running a Byzantine fault-tolerant (BFT) consensus algorithm, the paper says. Anyone from the public can connect to the network and participate as a RN, who are assigned the duty of double checking blocks that have been propagated by CNs.
In today's release, Ground X describes new details of the consensus mechanisms, saying:
The subsidiary said in the release that, alongside the mainnet launch, it's announcing a "governance council" to oversee the blockchain network's development and operations. Already, it says, major firms such as LG, Big Pharma firm Celltrion and Philippines bank UnionBank are taking places on the council.
