Aprobación

En el paso anterior, agregamos invocaciones externas, permitiendo a los participantes que no son miembros de la gobernanza realizar invocaciones y modificar el estado de los sujetos. Sin embargo, esto permitiría que cualquier entidad, sea certificadora o no, pueda hacerlo. Como no queremos vincular directamente a los laboratorios involucrados con nuestra gobernanza, optaremos por utilizar un sistema de aprobación.

Este enfoque implicaría delegar la autorización a un tercero de confianza, quien tendrá el conocimiento necesario para aprobar o rechazar eventos de certificación.

Por lo tanto, llegados a este punto nos centraremos en incluir un nuevo miembro que será el responsable de llevar a cabo la tarea mencionada anteriormente. Este nuevo miembro se llamará Organización Española de Alimentación (SFO).

Para incluir SFO, primero debemos crear el nuevo nodo. Por tanto, procederemos a ejecutar el siguiente comando:

docker run -p 3003:3000 -p 50003:50000 -e KORE_PASSWORD=polopo -e KORE_FILE_PATH=./config.json -v ./config2.json:/config.json koreadmin/kore-http:0.5-sqlite

Si un evento requiere aprobación o no depende directamente de su especificación en el método contrato. Por lo tanto, debemos agregar contract_result.approval_required = true; a nuestro contrato de la siguiente manera:

Usaremos la utilidad base64 de Linux para obtener el contrato actualizado y el resultado será:

base64 main.rs

A continuación, procederemos a modificar las propiedades de gobernanza. En este caso, haremos cambios en el contrato y convertiremos al nodo SFO en miembro de la gobernanza, así como en aprobador y testigo de los sujetos con el esquema Wine. Para comenzar, visualizaremos las propiedades que queremos modificar en nuestra gobernanza actual:

Después de realizar el cambio deseado, nuestras propiedades deberían verse así:

El resultado obtenido será:

A continuación, procederemos a invocar el método del contrato responsable de actualizar sus propiedades. Para hacer esto, ejecutaremos lo siguiente:

Después de enviar la solicitud de actualización de gobernanza, debemos obtener una solicitud de aprobación:

curl --request GET 'http://localhost:3000/approval-requests?status=Pending'

Copiaremos el valor del campo id. Sin embargo, esta vez también se requiere la aprobación de WFO. Por tanto, realizaremos las siguientes dos acciones:

curl --request PATCH 'http://localhost:3000/approval-requests/{{PREVIUS-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{"state": "RespondedAccepted"}'

curl --request PATCH 'http://localhost:3002/approval-requests/{{PREVIUS-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{"state": "RespondedAccepted"}'

Como en pasos anteriores, el nuevo nodo no podrá recibir la gobernanza sin autorización previa. Por lo tanto, debemos preautorizarlo antes de proceder:

curl --request PUT 'http://localhost:3003/allowed-subjects/{{GOVERNANCE-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{
    "providers": []
}'

Una vez completada la preautorización, al consultar nuevamente nuestra gobernanza, deberíamos ver su correspondiente nueva versión:

curl --request GET 'http://localhost:3003/subjects/{{GOVERNANCE-ID}}'

Para verificar el correcto funcionamiento de los pasos anteriores, realizaremos una nueva solicitud al método de certificación orgánica con una invocación externa. Primero, generaremos la firma del evento que queremos emitir usando kore-Sign con el siguiente formato. Reemplace subject_id con el identificador de nuestro asunto Wine:

kore-sign 'f855c6736463a65f515afe7b85d1418c096ed73852b42bbe4c332eb43d532326' '{"Fact":{"subject_id":"{{SUBJECT-ID}}","payload":{"OrganicCertification":{"fertilizers_control":false,"pesticides_control":true,"analytics":true,"additional_info":"test"}}}}'

Incluiremos el resultado de esta ejecución en la siguiente solicitud:

curl --request POST 'http://localhost:3001/event-requests' \
--header 'Content-Type: application/json' \
--data-raw {{PREVIUS-RESULT}}

Esto debería ser similar al siguiente:

curl --request POST 'http://localhost:3001/event-requests' \
--header 'Content-Type: application/json' \
--data-raw '{
    "request": {
        "Fact": {
        "subject_id": {{SUBJECT-ID}},
        "payload": {
            "OrganicCertification": {
            "additional_info": "test",
            "analytics": true,
            "fertilizers_control": false,
            "pesticides_control": true
            }
        }
        }
    },
    "signature": {
        "signer": "EzzmRjc8CtjzHu3MKmuTgnmOTgrJlYZj1D2DCZ9nN7Vk",
        "timestamp": 1689851094828637107,
        "value": "SEBxyRnCxTc2T2tA3W4x6RHHT39_6DIKHtxiXMzahz-NEkP8k1r1qWz-Xdq0dN_y-b5BOciQb50pHOzQfy8dDqBQ"
    }
}'

A continuación, revisaremos las solicitudes de aprobación que llegaron a SFO:

curl --request GET 'http://localhost:3003/approval-requests?status=Pending'

Copiaremos el valor del campo id y denegaremos esta solicitud ya que consideramos que este evento ha sido emitido por una entidad en la que no confiamos:

curl --request PATCH 'http://localhost:3003/approval-requests/{{PREVIUS-ID}}' \
--header 'Content-Type: application/json' \
--data-raw '{"state": "RespondedRejected"}'

Luego de realizar una nueva consulta al sujeto Wine que creamos, este debe tener un valor sn de 3, ya que, a pesar de rechazar el evento, esta ocurrencia queda registrada en la cadena. Además, el campo organic_certified aún debería ser true ya que el evento de modificación ha sido rechazado, y si hubiera sido aceptado, este campo sería false:

curl --request GET 'http://localhost:3001/subjects?subject_type=all&governanceid={{GOVERNANCE-ID}}'

{
    "subject_id": "JYmrV61dombhKZe9KSS8ZgRFL86u19roDjIfXIc4f-98",
