CROSSVALUE Chain Global Hackathon in Hanoi Event Report!

We are pleased to introduce the very first CROSSVALUE Chain Global Hackathon held in Hanoi, Vietnam from June to August 2023.



The theme of this hackathon was the development of an application on the CVC Testnet (KURA), which precedes the CROSSVALUE Chain (CVC) mainnet deployment.

The hackathon was evaluated by the following judges:

Tokuro Uhara (CROSSTECH CEO & Co-founder)
Yuma Tanimoto (CROSSTECH CSO & Co-founder)
Ikeda Hideki (Zaif CTO & Diector)
Dr. Dang Minh Tuan (Vietnam Blockchain Union Chairman)
Duong Thanh Hai (Icetea Labs & GameFi.org CTO)
Dr. Hiro Takahashi (CROSSVALUE Chain Chief Architect) *Participated only in pre-screening



Many people were interested in the contest from the start of the call for entries, and in the end, 63 teams entered the competition. It should be noted 19 of the entries were student teams where the winners were selected from among the best contestants.

The projects making it to the final round were all very talented developers, and the heated pitches at the demo day made for a very heated event, with the rankings shifting until the very last minute.

Without a doubt, they will grow into projects that will strongly contribute to the CVC ecosystem in the future.
