Mold on homemade sriracha
Do NOT eat this. You figured out right that the stuff on top is mold. The thing that makes mold dangerous is the mycotoxins produced by it and these will likely remain in the sauce even if you scrape off the furry stuff. So eating this comes with high risk of affecting your health. Move it to the trash bin right away.
I would recommend to try again with a recipe with vinegar added and also to use containers that are more appropriate for doing fermentation. This means to minimize the amount of air in the container that could possibly contain any spores and to minimize the surface of the food exposed to the air. So using a bottle will serve your purpose much better than the only half-full glasses on your pictures.
Also be very careful to sterilize the containers and tools getting in contact with the sauce before starting the fermentation.
