We are a Japanese company operating our proprietary private blockchain technology, , to leverage blockchain technology in various applications in a range of industries. We believe that Japan is lagging behind the international progress of blockchain system development. One reason for the slow development progress is the extremely small number of engineers in Japan who can handle blockchain technology and the high cost of learning. We aim to increase the number of use cases of GLS, and offer a general-purpose System Development Kit (“SDK”) for external engineers to improve GLS. Our mission is to keep updating GLS and make it an infrastructure in the coming .

While a conventional blockchain constitutes a transaction ledger database by connecting blocks in series, our GLS realizes a cyclic network structure for nodes (computer devices participating in the blockchain network), making it easy for multiple nodes participating in the network to simultaneously execute approval processes in parallel, thereby speeding up the transaction approval process and ensuring scalability.

In comparison, we believe that GLS has a wider range of business applications few seconds to complete one transaction due to the need for enhanced security measures. The partly because GLS enables finality by adopting a definite consensus algorithm. conventional blockchain systems generate blocks in series. In comparison, GLS generates blocks in parallel and the approval time for one transaction in GLS can reach 0.016 seconds while offering enhanced security at the same time. Emergency Stop Parallel Processing and Auto-scale Functions The conventional blockchains cannot be stopped in the event of emergencies because of their The conventional blockchain networks expand at random and consolidate processing in a lack of a kill switch. In comparison, GLS can be stopped in an emergency due to the presence of single node, which represents one of the personal computers in a blockchain network. In a kill switch. comparison, GLS arranges nodes within the network in a circular fashion and reduces the processing load for each node by sharing the processing load among intermediate processing nodes, thereby accommodating the user’s different levels of needs.

To eliminate number of transactions at high speed, making it possible to set fees flexibly. security concerns related to a single point of failure, GLS employs intermediate processing nodes, which are independent of the nodes that make up the blockchain network and process the actual transactions. Even if the intermediate processing nodes are stopped, the transactions cannot be tampered with. To reduce the impact of attacks on intermediate processing nodes and any unauthorized access, GLS allows the use of firewalls and other means to prevent cyberattacks, thereby providing transaction security. 8 See offering documents for further risks and disclosures.
