授業の概要と目的（何を学ぶか）Outline and objectives
Blockchain is an emerging technology platform for developing decentralized applications and data storage, over and beyond its role as the technology underlying the cryptocurrencies. This course aims to provide a conceptual understanding of the function on blockchains as a method of securing distributed ledgers, how consensus on their contents is achieved, and the new applications that they enable.
到達目標Goal
(1) To understand the structure of a blockchain and why it is better than a simple distributed database.
(2) To analyze the incentive structure in a blockchain-based system and critically assess its functions, benefits, and vulnerabilities.
(3) Understand what constitutes a “smart” contract, what are its legal implications, and what it can and cannot do, now and in the near future.
(4) To evaluate the setting where a blockchain-based structure may be applied, its potential, and its limitations.
授業で使用する言語Default language used in class

授業の進め方と方法Method(s)（学期の途中で変更になる場合には、別途提示します。 /If the Method(s) is changed, we will announce the details of any changes. ）
The lectures will be given in a highly interactive manner. The students will be asked to discuss the fundamental distributed database issues and consider their own solutions. Most homework assignments will be on open questions without standard answers. The students will be encouraged not only to learn the knowledge but also to think about how it can be used.
