Abstract(in English) | Bitcoin published in 2008 has been supported development of cryptographic currency in recent years. The blockchain is one of the key technologies of the Bitcoin and its various applications are discussed. Proof of Work (PoW) is often adopted as a consensus protocol in the blockchain, and a right of the vote is given for a proportion of computer’s computational power. Bitcoin, most widely used in cryptographic currency, also adopts PoW. However, PoW-based blockchain application requires a long period until completing it’s payment. Then, Bitcoin cannot complete its payment from 10 minutes to one hour. This paper discusses parameters of Bitcoin in order to accelerate completion of the payment with maintaining the security strength, and applicability of the parameter setting. Key words Proof of Work Blockchain double-spending fast-payment Bitcoin |
