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.

Case
HOW- Goal
- Perform Edwards25519 point and scalar multiplication and addition with filippo.io/edwards25519
- Packages
- Created
- 2026-08-23T17:54:13Z
Contract
- Point.ScalarBaseMult multiplies base point by scalar
- Point.ScalarMult multiplies arbitrary point by scalar
- Scalar.Multiply performs scalar multiplication
- ScalarMult satisfies associativity s2*(s1*B) == (s1*s2)*B
- Point.Add adds identity point leaving point unchanged
- Point.SetBytes roundtrips serialized point bytes
- Scalar.SetCanonicalBytes roundtrips canonical scalar bytes
- Scalar.SetCanonicalBytes rejects non-canonical scalar bytes
