About Us

Solomon Lederer, Ph.D.


Dr. Lederer has over 15 years of technical experience in computer system design and programming. He has been teaching about blockchain and Ethereum for 3 years and recently co-authored Blockchain: A Practical Guide to Developing Business, Law, and Technology Solutions. Prior to working on blockchain technology, he was a software architect at at The Wall Street Journal and managed the transition from legacy publishing infrastructure to the Amazon cloud, migrating hundreds of apps to the AWS platform, redesigning the publishing flow and replacing many services to use AWS alternatives from databases to load balancers to queuing and messaging systems.

Prior to WSJ, Lederer was a software engineer at Morgan Stanley rebuilding their global margin requirement calculation system for increased accuracy and speed. The system provides cross-asset portfolio-based margin calculations and risk measures in real time. It also incorporates U.S. regulatory rules and assesses margin requirements. 

Prior to Morgan Stanley, Dr. Lederer worked on distributed networks both at BAE Systems, a defense contractor, and as a PhD candidate. At BAE Systems he held a DoD TS (top secret) clearance to develop a novel mobile ad-hoc network for the US Air Force. As a PhD student he developed original algorithms that determine the location of thousands of randomly placed nodes without GPS.  By combining disciplines of algorithms, sensor networks, and computational geometry, Dr. Lederer was able to solve the localization problem for ad-hoc sensor networks.
