Yesterday I posted a challenge. Tell me how I made my upvote arrow spin! I requested a couple pieces of information and got a lot of responses.
I found this using a Linux based computer and the chromium (open source) browser. Every time that I pulled up my vote slider and double clicked, I was able to make the arrow animation work. I tried it on all the computers in the house. I don't have Windows or Apple, but I did try one with Fedora and none of my browsers could spin it.
The winner said it works on Debian, using Firefox. I might not have believed it but there is a supporting video on their post. Good going!
Remember. Your job is to make sure people know that simply putting it "on the blockchain" does NOT mean that it is on the Bitcoin (or another reliable decentralized) blockchain.
