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

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert random is a function exported by nanoid
  2. assert random returns a Uint8Array of the requested byte length
  3. assert random returns an empty Uint8Array when requested length is 0
  4. assert random generates cryptographically distinct byte sequences across consecutive calls
  5. assert random outputs bytes spanning the full 0-255 uint8 range over multiple calls
  6. assert random functions as a compatible RNG source for customRandom
