講座內容介紹：

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.

自比特幣發明以來，加密數字貨幣的類型極速增長。相比舊種類而言，許多新的數字貨幣在不同方面做了些許改善，比如用了能源消耗更少的共識機制，更強的加密技術，或者更靈活的交易協議。與傳統經濟部門類似，這些創新會給創新者產生成本。本文考慮一個關于數字貨幣的質量階梯模型，并用此來回答私人發行貨幣的市場中，創新者是否有激勵進行社會“合意”的創新。
