The recently concluded competition received quite attention and even the organizers are showing their excitement about the same. The winners collectively received over $70,000 worth of prizes. The organizers say:

The BitHack is important to us because it taps into a core benefit of Bitcoin: permissionless innovation. Anyone from anywhere in the world could submit a Bitcoin project to BitHack v2, as long as it met our simple guidelines. Over 300 teams registered, and we received 84 qualified submissions from twelve different countries. Many of these submissions came from people who were not able to build payment applications before Bitcoin.

The Winners Were Tested Strictly

The first test was about creativity wherein the participants were asked to find a new use case and not just create another wallet as the organizers wanted to see apps that make Bitcoin easy to use, and show off new use cases that aren’t possible with existing payment methods. Additionally, they wanted to test usefulness i.e. make Bitcoin easy to use.

The organizers claim that they were looking for apps that make Bitcoin more approachable for a mainstream audience and know how Bitcoin can go viral, or reach 100M new people in the coming years. Additionally, they wanted execution i.e. pay attention to details and functionality of the app.

Talking about the winners the organizers claim that true to Bitcoin’s global potential, the five winning projects were built in four different countries, each with a unique economic climate: Pakistan, Philippines, Germany, and the U.S.
