# Kinetic Gain Protocol (KGP)

> An open, versioned, machine-verifiable profile for attaching signed, hash-reproducible provenance to web claims, discoverable by search crawlers and answer engines.

Canonical spec: https://kineticgain.com/protocol/
Machine manifest (KGP/0.1): https://kineticgain.com/protocol/kgp/0.1.json
Steward: Kinetic Gain LLC. Editor: Miz Causevic. Status: draft (v0.1).

Honest status: reference implementations across the Kinetic Gain estate are rolling out. There are no external adopters yet. This is an open specification with reference implementations, not an established industry standard.

## What it is
KGP unifies three already-published pieces into one conformance profile: the AI Evidence Format (the evidence object), the Evidence Bundle manifest, and ed25519 signing published under /.well-known/. A conformant page attaches a machine-readable evidence object to a claim, optionally carrying a reproducible sha256 content hash (Level 2) and an ed25519 signature (Level 3), and declares conformance with a schema.org conformsTo edge pointing at this canonical spec.

## The problem it solves
Answer engines and search crawlers cannot tell an authored, accountable claim from synthetic filler. A page that emits a KGP evidence object gives a machine three things at once: a content_hash it can recompute to confirm the exact text, an ed25519 signature proving which entity stands behind it, and a conformsTo pointer to a named standard. That is a verification path, not just an assertion.

## How to verify a claim (reproducible right now)
The content_hash is a plain sha256 of the exact claim text. Example:
  printf '%s' 'The Eiffel Tower is 330 metres tall.' | sha256sum
  => 22d55b4f4a196374a8444337fc5005edc190b7724912c00e0ecf7b5c22201e67

## Conformance levels
1 Attach: a machine-readable evidence object accompanies the claim.
2 Verify: the object carries a reproducible sha256 content_hash of the claim text.
3 Sign: the content is ed25519-signed over the RFC 8785 canonical form; the public key is published under /.well-known/.

## How KGP differs from adjacent standards
KGP does not replace C2PA (media provenance), sigstore or SLSA (software artifacts), or schema.org ClaimReview (fact-check claims). KGP is the web-discoverable, schema.org-tied, badge-linked evidence layer for arbitrary web claims, self-hostable via /.well-known/.
