type: /proofs/1.0/contract-invoke-response

Response to contract invoke request with a zero-knowledge proof that could be sent or not. In case proof response has been sent, then txHash property MUST be included to scope object of the generated proof.

{
    "did_doc": "<did_doc>",
    "scope": ["<generated zero knowledge proofs with or without txHash>"],
    "transaction_data": "{<information_about_smart_contract>}"
}
