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
- Buffer.from creates buffers from UTF-8 strings with matching byte contents and length
- Buffer.from creates buffers from hex and base64 encoded strings accurately
- Buffer.from creates buffers from byte arrays and truncates numbers to 8-bit integers
