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
- encodeU32 encodes an unsigned 32-bit integer into a Uint8Array using LEB128 encoding
- decodeUInt32 decodes LEB128 encoded bytes into an unsigned 32-bit integer value and returns nextIndex
- encodeI32 encodes a signed 32-bit integer into a Uint8Array using LEB128 encoding
- decodeInt32 decodes LEB128 encoded bytes into a signed 32-bit integer value and returns nextIndex
