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
- sha256 computes standard SHA-256 hexadecimal digests for strings and supports incremental streaming updates
- sha512, sha384, and sha224 produce expected cryptographic hash digests for byte inputs
- sha3_256 and keccak_256 compute distinct digests and shake128/shake256 support variable-length XOF output
- blake3 and blake2b compute fast cryptographic digests with optional custom output length
- computeHmacSha256 generates valid message authentication codes using SHA-256 and secret keys
- deriveHkdfKey, pbkdf2, and scrypt derive deterministic cryptographic keys with configurable iterations and work factors
- bytesToHex, hexToBytes, utf8ToBytes, concatBytes, and randomBytes convert and manipulate byte arrays correctly
