Plain Q&A

Short questions. Short answers.

What is open? Schemas, vocab, SDKs, verifier.
What is closed? Nothing in the protocol layer.
Which licence? Apache 2.0 for code. CC-BY-4.0 for vocab.
Where is the source? On GitHub. KYE-Protocol org.
Can I fork? Yes.
Can I contribute? Yes. Open a PR.
Will you take my fix? Yes if it follows the constitution.
Is the runtime open? Reference Gateway is. Hardened build is paid.

Plain take

Apache 2.0 SDKs. CC-BY-4.0 vocab. No runtime lock-in.

Three SDKs. One protocol. Same names.
Schemas and vocab versioned on GitHub.
Public JWKS. Open verifier.
Bring your own runtime.

Compatibility

Short take. Big idea.

Node 20+

All TypeScript packages require Node 20 LTS or higher. ESM-only.

Python 3.11+

The Python SDK uses StrEnum and the modern typing module.

Schema versioning

Every schema carries a $id with absolute URI under kyeprotocol.com/schemas/. Semver-locked.
