#PI Nicolas Kokkalis, an authority with a Stanford PhD and a pioneer in blockchain technology, is the co-founder and CTO of Pi Network, responsible for its technical development including mobile mining and SCP consensus architecture. He holds a background in distributed systems, human-computer interaction, social computing, and early smart contract frameworks—research conducted before Ethereum's emergence. Kokkalis has also been a Stanford educator, teaching the first blockchain course (CS359B), and a Silicon Valley entrepreneur, co-founding StartX, which has incubated over 1,300 companies valued at more than $26 billion, as well as founding Gameyola, a social gaming platform with over 20 million users, and conducting research at the University of Toronto and the Forth Institute of Computer Science in Greece. As the technical backbone of Pi Network, he led the development of mobile mining, SCP consensus, and inclusive encryption technology architecture. With a background as a Stanford computer science PhD, a blockchain academic pioneer, and a veteran Silicon Valley entrepreneur, Kokkalis is the technical soul of Pi Network, maintaining academic ties with Vitalik Buterin—who was once his student and research mentee—without any commercial ties.
