讲座内容介绍：

Ever since the first cryptocurrency, Bitcoin, was invented in 2008, the number of cryptocurrencies has exploded. Many of them were invented with various improvements over previous ones, such as a less wasteful consensus mechanism, a stronger cryptographic technology, and a more flexible transaction protocol. These innovations, just like innovations in more traditional economic sectors, are costly for the corresponding innovators. We introduce a quality-ladder model of digital currencies, and address the question of whether, in a decentralized market of privately-issued currencies, innovators have adequate incentives to innovate for the benefit of the society.

自比特币发明以来，加密数字货币的类型极速增长。相比旧种类而言，许多新的数字货币在不同方面做了些许改善，比如用了能源消耗更少的共识机制，更强的加密技术，或者更灵活的交易协议。与传统经济部门类似，这些创新会给创新者产生成本。本文考虑一个关于数字货币的质量阶梯模型，并用此来回答私人发行货币的市场中，创新者是否有激励进行社会“合意”的创新。
