邀请人：刘家佳教授
报告简介：数字资产是一种非货币资产，其形式为个人、企业、政府或各种组织拥有和控制的数据。数字资产包括目前非常流行的加密货币和NFT代币。他们的保护依赖于使用区块链技术设计的安全和隐私机制。本次演讲中将首先讨论对DeFi交易的各种攻击，这些攻击可能会极大地影响客户的加密货币收益，例如在Uniswap中。然后，我们将说明与数据交换相关的隐私问题，以及我们利用NFT实现数据可追溯性、隐私和交换公平性的方法。

Title: Digital Asset Protection: From DeFi to NFT in Blockchain Systems
Prof. Bin Xiao
The Hong Kong Polytechnic Univ.
Abstract:
The digital asset is a kind of non-monetary asset in the form of data owned and controlled by individuals, enterprises, governments, or various organizations. The digital assets include currently very popular cryptocurrencies and NFT tokens. Their protection relies on security and privacy mechanisms designed by using the blockchain technology. This talk will first talk about various attacks on DeFi transactions, which could dramatically affect a customer’s cryptocurrency gains, e.g., in Uniswap. Then, we will illustrate the privacy issues related to data exchange and our method of utilizing NFT to achieve both data traceability, privacy, and exchange fairness.
