Yongge Wang


Dr. Yongge Wang is a professor at UNC Charlotte. Dr. Wang has published extensively on research topics including algorithmic information theory, cryptography, and post-quantum security. Dr. Wang has proved several classical results in modern effective randomness research which are included as the fundamental theorems in most Algorithmic Information Theory graduate textbooks.  Dr. Wang is the holder of three patents and the inventor of two IEEE 1363 standardized techniques. Dr. Wang is one of the designers for fundamental W3C and IETF XML securitytechniques such as XMLENC and XMLDSig syntax. These standards are the starting point for all XML related security techniques. Dr. Wang played important roles in developing research and education programs at UNC Charlotte. Recently, Dr. Wang has been working on fully homomorphic encryption, garbled computation techniques, and apply these techniques to achieve privacy preserving computation in cloud. Dr. Wang has  designed quantum resistant public key encryption techniques RLCE (http://quantumca.org) and developed the software package readily to be integrated into current Internet infrastructure. Dr. Wang has developed the 4-step UNCC patented BDLS Byzantine Fault Tolerance protocol for blockchains. Dr. Wang is currently an academic advisor for the Cryptic Labs http://crypticlabs.org that builds a unique community of illustrious cryptography and security advisors, researchers and innovative blockchain entrepreneurs who work on decentralize and distributed trust.

Talk title: Digital currency, blockchain and decentralized finance (DeFi)

Abstract:  In this talk, we will briefly review and discuss a few popular digital currency initiatives (such as Chinese DC-EP, Facebook Libra) and their effort for Anti-Money Laundering (AML), Combating the Financing of Terrorism (CFT), sanctions compliance, and fight against terrorism financing and illicit activities. Specifically, we will briefly talk about Financial Action Task Force (FATF) guidance for a risk-based approach (e.g., Virtual Asset Service Providers (VASP)). Then we will briefly review a few important Decentralized finance cases (often called DeFi or open finance) that are mainly based on public blockchains.  Lastly, we will talk about fundamental consensus protocols for public blockchains and introduce the BDLS protocols which are the most efficient BFT protocols for permissionless and permissioned blockchains. BDLS protocols is by UNCC researchers.
