讲座内容 The success of decentralised cryptocurrencies has brought a new era in electronic currency research and development. The underlying technology, namely blockchain, has also been shown to have vast potentials in various domains. In this talk, we will first take a quick review on the existing cryptographic technologies used for providing security and privacy in some prominent blockchain-based cryptocurrencies. We then point out some vulnerabilities and limitations in the existing schemes, followed by some solutions to address those problems and some remaining challenges and open problems in the research domain.
