Generate an image
One click makes an image that never existed, and BitGraph proves it.
A position opens
BitGraph opens a fresh position. Its commitment is unpredictable, so nobody could know it in advance.
The image is drawn from it
Every setting of the bridge comes from that commitment, so the image could not have existed before the position opened.
The image is recorded in it
The finished image goes into that same position, between a Base block before and a Base block after.
