报告摘要Conceptualized 10 years ago as a core component of Bitcoin, blockchain has gained a vast amount of interest. Informally speaking, a blockchain is a distributed, shared, and immutable ledger that maintains a growing list of ordered records. It became extremely popular among the industries in the last few years. Many companies are exploring applications of blockchain beyond cryptocurrencies. In this seminar, the speaker will introduce blockchain and highlight some of the latest research works in this area, with an emphasis of how cryptography plays a crucial role. Examples of highlights include how cryptographic primitives such as ring signatures and zero-knowledge proofs can be used to enhance privacy in blockchain applications. He will also present applications of blockchain beyond cryptocurrencies and discuss gaps between the research community and these new applications areas. He will also share his views and some potential solutions on these issues
