W. Scott Stornetta


Partner & Chief Scientist

Dr. Stornetta is considered by many to be the co-inventor of the Blockchain. Dating back to 1991, his pioneering series of papers, written with co-author Dr. Stuart Haber at Bellcore, received the 1992 Discover Award for Computer Software, and were featured in the New York Times in 1995. This helped lay the foundation for Bitcoin and other digital currencies (for example, of the eight citations in the original Bitcoin paper, three reference his and Dr. Haber’s work).

Dr. Stornetta was Assistant General Manager of the 125-person Mathematical and Computer Sciences Laboratory.  Dr. Stornetta consulted for many years, evaluating the commercial potential of emerging technologies on behalf of universities, commercial research labs, and venture capital interests. Along with Dr. Haber, he co-founded Surety, a Bellcore spinoff.  Surety’s offering constituted the first commercial deployment of a blockchain.

Dr. Stornetta received his Ph.D. in physics from Stanford University, after attending MIT, Harvard, and Brigham Young University.


Cory Myers


Senior Technology Analyst

Mr. Myers was an early engineer and then Network Architect at Trinity Mobile Networks, a developer of mesh-network technology.  In addition to coauthoring two patents (pending) on the control-plane architecture and routing techniques of JumpnetSDN, Trinity’s software-defined network for mobile devices, he guided the technical team’s development-operations (“dev-ops”) practices and advised internally on matters of performance, scaling, and security.

Mr. Myers studied philosophy at Deep Springs College and Yale College and was an undergraduate fellow at Yale Law School’s Information Society Project, where he assisted research on the Federal Communications Commission’s rulemakings on network neutrality.  He serves on the board of the Telluride Association, a nonprofit educational organization based in Ithaca, New York.

Stuart Haber


Much of the groundwork on which the Bitcoin blockchain and all the other blockchain concepts that have come after have been based on the foundational principles of Stuart Haber and his colleague W. Scott Stornetta’s work in 1991.

For more than 30 years, Dr. Haber has made significant contributions to the field of cryptography, distributed computing, and blockchain technology. He is the co-inventor of a number of Surety patents. Over the course of his career, Dr. Haber has lectured and published a number of scientific journals and articles on both theoretical and practical aspects of cryptography and distributed computing. He also contributed research materials in the field of electrical engineering.

Together with Stornetta, he has co-authored a number of important publications in the field of cryptography, some of which include: “How to Time-Stamp Document”, “Secure Names for Bit-Strings”, and “Improving the Efficiency and Reliability of Digital Time-Stamping” just to mention a few. Dr. Haber has also published research materials on the theory of computing, algorithms, and computer security.

Several aspects of the Bitcoin blockchain architecture are based on Dr. Haber’s work. The third, fourth, and fifth entries in the bibliography of the Bitcoin whitepaper are references to Dr. Haber’s work in cryptographic time-stamp protocols. From 2004 to 2011, Dr. Haber served as a member of the Board of Directors of the International Association for Cryptologic Research (IACR). Dr. Haber’s Erdös number is 2. Dr. Haber holds both M.Phil. and Ph.D. degrees from Columbia University.
