Session 1: Opening Keynote
Session Chair: Kazue Sako

Yassir Nawaz
Executive Director, JPMorgan Chase & Co.

Blockchain and Cryptography at JPMorgan Chase

An overview of JPMorgan's efforts to build a world class enterprise focused blockchain platform. The goal was to create a platform that is open source and free to use but also satisfies financial regulators, can be governed easily, and preserves privacy. This was achieved via Quorum, which is an enterprise focused version of Ethereum. Quorum is designed for applications requiring high speed and high throughput processing of private transactions within a permissioned group of known participants. A few research areas related to blockchain and cryptography that are of practical interest to JPMorgan will also be highlighted.

Yassir Nawaz is an Executive Director and a Distinguished Engineer in Global Cybersecurity at JPMorgan Chase (JPMC). He chairs the JPMC Cryptography Center of Excellence and helps drive security strategy and architecture for cloud, applications, and big data. Prior to joining JPMorgan he worked as a Technology Fellow at Pitney Bowes Advanced Technology Labs where he led the security and privacy research for the firm and helped develop several security platforms. He has filed 10 patents (5 granted) and published 10 technical papers in the area of digital privacy and security. He holds a Ph.D. in Cryptography & Information Security from University of Waterloo, Canada.
