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. pgio.AppendInt16 appends big-endian int16 to buffer
  2. pgio.AppendInt32 appends big-endian int32 to buffer
  3. pgio.AppendInt64 appends big-endian int64 to buffer
  4. pgio.AppendUint16 appends big-endian uint16 to buffer
  5. pgio.AppendUint32 appends big-endian uint32 to buffer
  6. pgio.AppendUint64 appends big-endian uint64 to buffer
  7. pgio.SetInt32 writes big-endian int32 into existing buffer slice
