# Operating an Energy Web VCC Runtime

This section provides a step by step guide on how to operate the Energy Web Verified Compute Cloud (VCC) Runtime.

## Getting started

Download the latest version of the Energy Web VCC Runtime here.

Install the downloaded installation file based on your operating system.

Upon running the application, it does not display any window or screen. Instead, the Energy Web VCC Runtime logo displays on the system tray.

## Understanding different runtime status

Below are the different runtime status and their meaning.

<table><thead><tr><th width="203.9375">Status</th><th>Description</th></tr></thead><tbody><tr><td>⚪ <strong>No Runtime Set</strong></td><td>There is no seed phrase configured in the runtime.</td></tr><tr><td>⚪ <strong>Validating</strong></td><td>The runtime is configured with a seed phrase and is currently validating if it has an operator linked to it.</td></tr><tr><td>🔴 <strong>No Operator Linked</strong></td><td>An error state when no operator is linked with the account associated with the configured runtime seed phrase. The runtime checks every minute if the runtime account is already linked to an operator. Once an operator is already linked, this state automatically moves to the "Not Started" state.</td></tr><tr><td>⚪ <strong>Not Started</strong></td><td>The runtime has successfully configured the seed phrase but is not yet running.</td></tr><tr><td>🟠 <strong>Starting</strong></td><td>The runtime is initiated to run.</td></tr><tr><td>🟢 <strong>Started</strong></td><td>The runtime has downloaded, installed, and deployed the Energy Web VCC Runtime Protocols of the subscribed solution groups. The protocols are also running and waiting for the trigger for them to execute business computations to derive verified, consensus-based results.</td></tr></tbody></table>

## Setting-up the runtime seed phrase

To set the runtime seed phrase, simply click on the "Set Runtime Seedphrase" from the menu.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FO5jWOzDYhXfFcAje8X2c%2Fimage.png?alt=media&#x26;token=23cb8ed9-bc18-4598-8787-d5191552b5cf" alt=""><figcaption><p>Energy Web VCC Runtime account address is displayed on the menu after configuration</p></figcaption></figure>

### Generating the Runtime Seedphrase

If there is no seed phrase available yet, this can easily be created from the Import Runtime Account screen by simply clicking on the *Create New* tab. Then, click on the *Generate account* button so the system can securely generate the 12-word recovery phrase for the new VCC Runtime account.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FmQcSO3DBL5uTEPxtwJUX%2Fimage.png?alt=media&#x26;token=1b9807ba-583d-414e-82c5-0c22374c2fd8" alt=""><figcaption><p>Create New VCC Runtime Account</p></figcaption></figure>

The generated 12-word seed phrase gets displayed on the screen. The system requires these to be backed-up. To do so, click on the *Backup Mnemonic* button then provide the desired file name and folder location to download the backup.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FMyGayiVFxjo9kPBrEgiA%2Fimage.png?alt=media&#x26;token=45a179f7-f047-476f-a9f8-58d12fbc0183" alt=""><figcaption><p>Backup VCC Runtime Seedphrase</p></figcaption></figure>

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FQQfEO6OqlzT4bNXNRvKL%2Fimage.png?alt=media&#x26;token=0c72c605-ff41-4b81-aa58-040b284d49c0" alt=""><figcaption><p>Choose seed phrase backup file name and folder location</p></figcaption></figure>

After backing-up, the "Backup Saved" status gets displayed. Click on the *Continue* button to proceed.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FdTU5OtWl2yQaVWID7npl%2Fimage.png?alt=media&#x26;token=46469c78-7cee-4feb-ad8f-cee178d223fd" alt=""><figcaption><p>VCC Runtime Seedphrase backup saved</p></figcaption></figure>

Confirm the backed-up recovery seed phrase by entering them into the confirmation form. Then, click on the *Confirm* button to proceed.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FKDynD5vocxtZxIAEACH1%2Fimage.png?alt=media&#x26;token=af031db8-c744-4193-9466-8707117533bb" alt=""><figcaption><p>Confirm backed-up seed phrase</p></figcaption></figure>

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FuJ8nQLgC8hv6MzAdSmg1%2Fimage.png?alt=media&#x26;token=db6edb8c-cc37-4309-aff7-e51be84f1e7d" alt=""><figcaption><p>New VCC Runtime account is created</p></figcaption></figure>

The newly generated seed phrase gets automatically set. Since this is a new account, the runtime status is set to "No Operator Linked".

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2Fugm1ckPko1HR7OYIlhle%2Fimage.png?alt=media&#x26;token=5b203da4-4e3a-460f-8019-37145ce15f6a" alt=""><figcaption><p>Newly generated seed phrase is automatically set</p></figcaption></figure>

### Handling "No Operator Linked" Error

In the event that the imported seed phrase is not linked to an operator, the "No Operator Linked" status is displayed.

<figure><img src="https://4257445316-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fnf3YeoQlQerc93GsC2Me%2Fuploads%2FwB2DGAeMB7Y0czvsz10D%2Fimage.png?alt=media&#x26;token=f77d36d4-114b-4b8d-b1f7-a8fe9bb341c2" alt=""><figcaption></figcaption></figure>

To handle this case, there are 2 options:

1. Wait for the system to automatically detect that an operator is linked to this Energy Web VCC Runtime account
2. [Reset](#resetting-the-configured-energy-web-vcc-runtime-account) the last configured account, and then configure it again using the same seed phrase

In the event that the VCC is newly subscribed to, and is not yet appearing the *Runtime Details* screen, click on the *Refresh* icon to manually check if it has been synced into the runtime.&#x20;

However, the runtime automatically syncs any change to the subscriptions, VCCs, and its protocols such as:

* If there are new subscriptions, the runtime automatically syncs the VCC details, waits for the next reward period, and automatically install any VCC protocols in the newly subscribed VCC
* If there are VCC expiries or unsubscriptions, the runtime automatically uninstalls all VCC protocols of the expired or unsubsubcribed VCC then removes its details accordingly - preserving only the application logs
* If there are new VCC protocols, the runtime automatically installs them
* If there are VCC protocol removals or expiries, the runtime automatically uninstalls them

{% hint style="success" icon="arrow-progress" %}
The runtime is only terminated from the system tray. However, it will still operate in the background as a service. This means that if the VCC Runtime is in "Started" state, it will continuously execute the deployed VCC protocols and will actively submit votes. To perpetually close the runtime, the user has to manually terminate it through the Task Manager or Terminal/Console of their respective systems.
{% endhint %}
