Recently, Kain Warwick, the founder of Synthetix, publicly announced on social media that he had invited prominent cryptocurrency investor Su Zhu to a duel on the karate combat platform Karate Combat in Singapore. Along with the invitation, Kain requested a response within 24 hours from Su Zhu to prevent him from ignoring the matter. However, in response to Kain's challenge, Su Zhu declined. He mentioned that he had already privately apologized to Kain several months ago, but it seemed that Kain had overlooked it. Su Zhu also stated that he had interacted with members of the new protocol team under Synthetix and Kain himself in Brussels, but Kain had disclosed their private information without justification. Expressing confusion and dissatisfaction with Kain's actions, Su Zhu politely declined the challenge and wished him well. It is noteworthy that this is not the first time Kain and Su Zhu have clashed. Earlier in 2021, when Su Zhu announced his departure from Ethereum, they had a heated debate on social media, and this incident has once again brought the two into public attention.
