[Challenge] Blind Implementation Test — can you implement CPS-0001 from spec alone?

[RaymondHWu]

We are running a blind implementation test for CPS-0001.

The question

Can someone implement a conformant producer or verifier without reading the original source code — using only the spec, schema, and test vectors in this repository?

The challenge (30–90 minutes)

1. Read START_HERE.md
2. Write a program (any language) that produces a valid Continuity Receipt
3. Run the CLI verifier against your output

You need SHA-256, Ed25519, and JSON. No sensor. No MyShape. No prior knowledge.

We want 3–5 independent implementations

Pass or fail — both are data. If you try, tell us:

• How long it took
• Where you got stuck
• What was unclear

Known limitations

See PROTOCOL_STATUS.md on the main implementation repo.

This is a research test, not a product launch. Research by The Continuity Lab.
