In the "Presidential hackathon" held in Taiwan, secondary voting was used for the winning project
In the "Presidential hackathon" held in Taiwan, a second round of voting was used for the winning project. This context was described as "initial voting by judges + secondary voting by citizens". The details can be found in the link(https://gyazo.com/99b25a72a9661c77bd09f70fb102f81d). The concept of secondary voting was implemented to ensure a fair and inclusive selection process. The "Presidential hackathon" in Taiwan is a platform where important issues are voted upon. Participants select crucial items from over 169 sustainable development goals and vote on them. Despite numerous goal proposals, only 5 items are chosen as particularly significant and given the status of the President's commitments. The voting system used in the "Presidential hackathon" is inspired by blockchain technology and is called "quadratic voting". This system has been in use for the past 3 years and has proven to be highly effective in ensuring accurate representation and fair decision-making.
