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. db.NewTransaction creates read-write transaction that persists key-value entries upon Commit
  2. db.NewTransaction creates read-only transaction that retrieves values via Txn.Get and Item.ValueCopy
  3. Txn.Get returns badger.ErrKeyNotFound for non-existent keys
  4. Read-only transactions return badger.ErrReadOnlyTxn on write operations Set and Delete
  5. Txn.Delete removes existing entries in a read-write transaction upon Commit
  6. Txn.Discard aborts uncommitted modifications without altering the database
