| Abstract(in English) | In the Bitcoin network, there is no construction to give trust to the participating nodes. On the other hand, there is PKI as a infrastructure technique for giving trust to a web site. So far, PKI research using blockchains has been actively, but research on security management of certificates using smart contracts is the main focus. In this paper, we propose a method to give trust to nodes using tokens for blockchain 1.0 which do not use smart contract. This method has the advantage that it can be realized by the functions of the existing cryptocurrency without adding a new function. Furthermore, In the testnet environment of Bitcoin which is a blockchain 1.0, we experimentally verify that the token functions as a certificate. |
