**James “Jim” Hormuzdiar** is a physicist and technology founder who has served as chief technology officer (CTO) of BlockApps since September 2014. He co-founded the company and was the primary architect of EthereumH, its Haskell-based [Ethereum](https://iq.wiki/wiki/ethereum) client.[\[1\]](#cite-id-nvq38x44eh)​[\[2\]](#cite-id-h905h3j601)​[\[3\]](#cite-id-hwzqje1jt4)​

## Early Life and Education

Hormuzdiar studied mathematics, physics, and engineering at the University of Connecticut from 1988 to 1994, and attended Yale University from 1994 to 1999. He holds a PhD in physics.[\[2\]](#cite-id-h905h3j601)​[\[1\]](#cite-id-nvq38x44eh)​

## Technology Career

Hormuzdiar was CTO of Safeweb, Inc. from 2000 to 2003, CTO of Robotgenius, Inc. from 2005 to 2011, and CTO of SmarTots from 2011 to 2012. Safeweb is also identified as SafeWeb and as now Symantec.[\[2\]](#cite-id-h905h3j601)​

He moved to China in 2011. While working in Beijing, he met Victor Wong, later his BlockApps co-founder, through a venture capitalist. Hormuzdiar said they became better acquainted after he moved back from China.[\[1\]](#cite-id-nvq38x44eh)​

## Ethereum and BlockApps

Hormuzdiar discovered [Bitcoin](https://iq.wiki/wiki/bitcoin) around 2014 and was initially skeptical. He later said that he changed his view after considering how a decentralized network could recover from bugs or exploits through a [hard fork](https://iq.wiki/wiki/hard-fork).[\[1\]](#cite-id-nvq38x44eh)​

By September 2014, Hormuzdiar had begun developing an [Ethereum](https://iq.wiki/wiki/ethereum) client in Haskell with Kieren James-Lubin. He built the client from scratch using Ethereum’s [Yellow](https://iq.wiki/wiki/yellow) Paper specification and the evolving codebase. His initial focus was the Ethereum Virtual Machine, while James-Lubin worked on the wire protocol. Hormuzdiar compared the C++ implementation, the Yellow Paper, and the Go implementation, and recalled that the paper only partly described the code as it was being implemented.[\[1\]](#cite-id-nvq38x44eh)​

At DEVCON1 in London, Hormuzdiar was part of the team that announced BlockApps STRATO alongside Microsoft’s Blockchain as a Service announcement. In his account, BlockApps stepped in to deliver after the Java client team withdrew from the Microsoft partnership; he recalled that Microsoft representatives were upset because an announcement had apparently already been made.[\[1\]](#cite-id-nvq38x44eh)​

## Physics Research

Before and alongside his technology career, Hormuzdiar coauthored research in theoretical particle and nuclear physics. His work addressed quantum chromodynamics (QCD), high-energy collisions, neutron-star superfluidity, and quantum dots.[\[2\]](#cite-id-h905h3j601)​

His publications include “Coulomb blockade conductance peak distributions in quantum dots and the crossover between orthogonal and unitary symmetry,” with Y. Alhassid and Niall D. Whelan, published in _Physical Review B_ in 1998; “Isospin fluctuations from multiple domains of disoriented chiral condensates,” with Stephen D. H. Hsu, published in _Physical Review C_ in 1998; and “Effective Field Theory of Neutron Star Superfluidity,” also with Hsu, in 1998.[\[2\]](#cite-id-h905h3j601)​

His subsequent work included “Pion breather states in QCD,” with Hsu, published in _Physical Review C_ in 1999; “On Spherically Symmetric Breathers in Scalar Theories,” with Hsu, in 1999; and “Particle Multiplicities and Thermalization in High Energy Collisions,” with Hsu and Gregory Mahlon, published in the _International Journal of Modern Physics E_ in 2003.[\[2\]](#cite-id-h905h3j601)​
