Biography

I'm the founder of Alt Research and AltLayer Network, an elastic and versatile scaling protocol for Web3. Before 2022, I was the director/GM of Parity Asia, which provides blockchain infrastructure (say OpenEthereum and Polkadot) for the decentralised Web. I'm selected to the Forbes 30 Under 30 Asia list, 2019.

Prior to that, I was the co-founder and CTO of Zilliqa. I led the efforts of designing and building the very first public blockchain platform with full-fledged sharding features including network/transaction/smart contract sharding. Meanwhile, I drived the collaboration with Xfers on the stablecoin initiative for Southeast Asia StraitsX. I also participated in blockchain projects with Mindshare, Singapore Exchange, Hg Exchange, etc.

Before 2018, I was a Research Fellow at the National University of Singapore. I got my Ph.D. in School of Computing at NUS in 2017.

My research interests span the areas of blockchain security, distributed system security, web security/privacy, and network security. I have proposed solutions to secure the web infrastructure from two perspectives – networking and system, e.g., addressing privacy / consensus issues in web overlays and identifying new attacks/vulnerabilities in web browsers.

My research work has been published in CCS, USENIX Security, PETS, RAID, ESORICS etc. I have received the Best Paper Award in W2SP (2014) and ICECCS (2014). My work got acknowledged by various vendors including Google and Apple (CVE-2014-7948 for Chrome and CVE-2015-5907 for Safari), as well as received attention from the media including Dailydot, Gizmodo and Techspot.
