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.
MIT-0

Contract
- encode converts an ASCII string to an array of UTF-8 byte numbers and decode restores the original ASCII string
- encode converts multi-byte Unicode characters into valid 2-byte and 3-byte UTF-8 sequences and decode reconstructs them
- encode converts an empty string to an empty byte array and decode converts an empty byte array to an empty string
- decode throws an error matching 'invalid UTF-8 encoding' when encountering invalid UTF-8 byte sequences or incomplete multi-byte sequences
