He is a fellow of the ACM , IEEE, and Singapore National Academy of Science (SNAS).


Blockchain technologies are taking the world by storm. Public blockchains, such as Bitcoin and Ethereum, enable secure peer-to-peer applications like crypto-currency or smart contracts.  Private blockchain systems, on the other hand, target and aim to disrupt applications which have so far been implemented on top of database systems, for example banking, finance and trading applications. 

In this talk, we first describe Blockbench, the first evaluation framework for analyzing private blockchains. It serves as a fair means of comparison for different platforms and enables deeper understanding of different system design choices. Next, we use Blockbench to conduct comprehensive evaluation of three major private blockchains: Ethereum, Parity and Hyperledger Fabric. I will also briefly introduce our distributed storage system, UStore, which has been designed to support Private Blockchain and Collborative Analytics as spplications.
