# Challenge system
Active challenges can be viewed from the 
tab.
The Custom tab shows active challenges of everyone you follow.
Users vote by clicking the vote button 
below the video they like most.
Casting a vote costs 1 VOTE token which is equivalent to $0.10 CAD.
The winning video earns between 1-25% of all VOTE tokens used during the challenge.
The closer the vote count ends up being, the larger the cut that the creator receives. This incentivizes creators to look for fair challenges.
The rest is distributed to all those who voted for it to win in the form of SKILL tokens.
Voters also continue to share in the success by earning royalties every time a video they voted for is sold on any marketplace.
Challenges last 72h.
