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. badger.DefaultIteratorOptions has PrefetchValues=true, PrefetchSize=100, Reverse=false, and AllVersions=false
  2. txn.NewIterator with badger.DefaultIteratorOptions traverses keys in ascending order
  3. modifying a copy of badger.DefaultIteratorOptions with Reverse=true traverses descending without mutating default
  4. badger.DefaultIteratorOptions supports prefix filtering with Seek and ValidForPrefix
