| Abstract(in English) | Blockchain technology has been used as the basis of crypto assets since the advent of Bitcoin, and new operation methods are being discussed daily. At the Security Summer Summit 2019, we confirmed that there are nodes that are also operating on the blockchain network of valueless crypto assets for which there is no reason to operate. And it was clarified that nodes of multiple stocks among them have biased regional dispersion. Therefore, in this paper, we check the operation status of various crypto assets, report the network status of each crypto asset, and discuss the risks of nondisruptive mechanism due to decentralization. |
