This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- PNG constructor initializes RGBA data buffer with size width * height * 4
- PNG.sync.write encodes image to PNG buffer and PNG.sync.read parses it back preserving pixel RGBA data
- PNG.prototype.pack and PNG.prototype.parse stream and asynchronously decode PNG image data
- PNG.bitblt copies a rectangular pixel block from source to destination PNG instance
