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 MurmurHash3 creates a hash instance and calculates 32-bit unsigned integer hash
  2. assert MurmurHash3 supports incremental string hashing matching single-pass calculation
  3. assert MurmurHash3 accepts custom seed affecting hash output
  4. assert MurmurHash3 supports reset method for reusing instance with optional new seed
  5. assert MurmurHash3 without new uses cached instance and resets on each call
