Assertion

An assertion is a claim or statement about the content, providing key details about actions or events in the asset’s lifecycle. Assertions allow creators and systems to document specific operations—such as content creation, editing, or distribution—making it possible to track the content's history transparently.

Example Assertion:

{
  "assertions": [
    {
      "label": "c2pa.actions.created",
      "data": {
        "action": "created",
        "softwareAgent": {
          "name": "content-creation-tool",
          "version": "1.0.1"
        },
        "parameters": {
          "height": 1024,
          "width": 1024
        }
      }
    }
  ]
}

Assertions are essential for documenting provenance, as they provide detailed information about every significant event in the content's lifecycle. By integrating the C2PA Standard, Hash Network ensures that assertions are cryptographically tied to the content and securely stored on the blockchain, enhancing transparency and trustworthiness.
