Winter School on blockchain

The year got off to an invigorating start for IOHK when a team of its researchers arrived in a chilly Shanghai for the first ever Winter School on cryptocurrency and blockchain technologies.

The 121-year-old Jiao Tong University – one of China’s leading institutions with alumni including the former president of China Jiang Zemin – hosted the conference in step with a rising interest in blockchain in China, including in its capital of commerce, Shanghai.

Professor Kiayias presented a double session on his work on proving the security of blockchain protocols. Jonathan Katz from the University of Maryland spoke on game theory, as…
