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.

- Buffer

Contract
- Buffer.alloc creates zero-initialized buffers of specified length and supports custom fill values
- Buffer.from creates buffers from byte arrays, existing buffers, and encoded strings
- Buffer.concat combines multiple buffers into a contiguous single buffer with optional totalLength
- Buffer.isBuffer identifies bare-buffer instances and rejects non-buffer values
- Buffer compare and equals evaluate buffer content ordering and strict byte equality
- Buffer copy and slice transfer and view slices of binary data between buffers
- Buffer read and write methods serialize and deserialize multi-byte integers in BE and LE byte orders
- Buffer write and toString encode and decode text using utf8, hex, and base64 codecs
