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. Bucket.Cursor creates a Cursor positioned at the beginning of the bucket
  2. Cursor.First and Cursor.Next iterate forward through key-value pairs in lexicographical order
  3. Cursor.Last and Cursor.Prev iterate backward through key-value pairs
  4. Cursor.Seek positions the cursor at the first key greater than or equal to the target prefix
  5. Cursor.Delete removes the current key-value pair under the cursor in a writable transaction
