内容摘要

Abstract: Conceptualized 12 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 talk, the speaker will introduce blockchain and highlight some of the latest development in this area. In particular, we will discuss the role of cryptography in blockchains, and why it is crucial. We will also discuss attacks that may circumvent present cryptographic protection mechanisms. Topics covered include threshold cryptosystems, anonymous credentials, ring signatures, zero-knowledge proofs, and post-quantum cryptography. Finally, we will conclude the talk with challenges related to the adoption of blockchain technologies and insights developed from our experience.
