Ph.D. student Ziliang Lai (supervised by Prof. Eric Lo) won the first prize of ACM Student Research Competition (SRC) Grand Finals 2022.
This year’s ACM SRC took place at 25 SIG-sponsored conferences (e.g., SIGMOD, SIGGRAPH, and etc), and the first prize winner of each conference advanced to the Grand Finals. As the first prize winner of SIGMOD SRC, Ziliang represented SIGMOD and won the first prize in the Grand Finals.
Ziliang’s work, Deterministic Concurrency Control For Private Blockchains, is on transaction execution of private blockchains, where a fundamental requirement is to ensure all blockchain nodes produce the same results after executing the transactions, i.e., determinism. Such a requirement implies executing transactions parallelly would be a problem because parallel transaction execution is non-deterministic due to OS scheduling. By introducing a novel deterministic concurrency control scheme, Ziliang’s work enables private blockchains with excellent parallelism, achieving over 200% throughput improvement over the state-of-the-art private blockchains.
