Dahlia Malkhi is an Israeli-American computer scientist who works on distributed systems and cryptocurrency.

Malkhi earned her bachelor's, master's, and doctoral degrees from the Hebrew University of Jerusalem, finishing her Ph.D. under the supervision of Danny Dolev.^[1] She taught at the Hebrew University until 2004, and then joined Microsoft Research at their Silicon Valley research center. In 2014, when Microsoft closed the center, she moved to VMware, a company working in cloud computing and platform virtualization.^[2][3]

She became a lead researcher at Novi Financial, a subsidiary of Meta Platforms (Facebook), and the lead maintainer of Meta's Libra cryptocurrency project. Libra later became Diem and Malkhi became chief technology officer at the Diem Association. In 2022, the Diem project shut down,^[4] and she moved to Chainlink Labs as their chief research officer.^[5]

In 2011, Malkhi became a Fellow of the Association for Computing Machinery "for contributions to fault-tolerant distributed computing."^[6] In 2021, she received the Technical Achievement Award of the IEEE Computer Society Technical Committee on Distributed Processing.^[7]
