报告摘要：
This talk gives trends and issues in research and application of BlockChain. We discuss the following items: (1) A short history of reformation in Japanese Banks and monetary easing by the government. (2) brief history of Virtual Crypto Currency, from DigiCash@Chaum by BitCoin@Nakamoto. (3) Two cryptographic tools, SHA and ECDSA with Bitcoin, and some patent matter. (4) Security and Privacy of Bitcoin and other Crypto Currency. (5) other applications of Blockchain beyond finance. (6) What we need for research and development on BlockChain from academic point of view. Finally, an importance discussion is about how long bitcoin's life time, which would be more serious for us.
樱井幸一教授简介：
Kouichi Sakurai received the B.S. degree in mathematics from the Faculty of Science, Kyushu University in 1986. He received the M.S. degree in applied science in 1988, and the Doctorate in engineering in 1993 from the Faculty of Engineering, Kyushu University. He was engaged in research and development on cryptography and information security at the Computer and Information Systems Laboratory at Mitsubishi Electric Corporation from 1988 to 1994. From 1994, he worked for the Dept. of Computer Science of Kyushu University in the capacity of associate professor, and became a full professor there in 2002.
