KDAG, KING of Directed Acyclic Graph, recently announced three innovational features, which will bring more security and convenience to the public chain landscape.

One of the key features is the unique “Hug” algorithm, that utilises embrace, instead of consensus, to solve data consistency. Through the original KDAG structure, the nodes embraced will get legal transaction references and achieve complete decentralisation.

Surf effect, another key feature, can help achieve high security of transaction privacy. Through randomness screening like the waves, it introduces nodes to obtain the legitimacy of the transaction, which can guarantee high security of transaction privacy.

In addition, the KDAG structure breaks the traditional chain structure and design a new consensus mechanism on KDAG. While achieving complete decentralisation and absolute security, it breaks the bottlenecks of the performance, and TPS can reach 30,000+ per second, offering users better experiences.

Committed to open ecology, open application and cooperation, KDAG is constructing an ecology with the above-mentioned technology. Being one of the latest and most advanced, the ecology can fully integrate with big data, cloud computing, artificial intelligence, 5G and other technologies, and can seamlessly connect with other blockchain networks to realise a shared and open community.

Till the end of the first quarter of 2020, the construction of the KDAG underlying main network has been completed. In the second and third quarter of 2020, the “Hug” algorithm of the KDAG underlying layer and the KDAG “butterfly” hug will be realised; while the KDAG “surf effect” will be completed by the end of this year.

The current achievement of KDAG technology is a major step for both KDAG and the whole blockchain industry, as transaction security and speed has always been the most concerned issues. We are looking forward to embracing all the groundbreaking technology launched by KDAG and a more secure, trusted and stable environment KDAG creates in the near future.
