### Intro

Dynamic Global Properties represents a set of values that are calculated during normal chain operations and reflect the current values of global blockchain properties.

[The API](#example-method-call) returns an object containing information that changes every block interval such as the head block number, the total vesting fund, etc.

### `Not Covered`<a style="float: right" href="#sections"><i class="fas fa-chevron-up fa-sm" /></a>

Fields not covered in this recipe are:

<ul>
{% for sections in site.data.objects.dgpo %}
{% assign sorted_fields = sections.fields | sort: 'name' %}
{% for field in sorted_fields %}
{% unless field.purpose %}
<li><code>{{field.name}}</code></li>
{% endunless %}
{% endfor %}
{% endfor %}
</ul>

### Example Method Call<a style="float: right" href="#sections"><i class="fas fa-chevron-up fa-sm" /></a>

To retrieve the current results for [`condenser_api.get_dynamic_global_properties`]({{ '/apidefinitions/#condenser_api.get_dynamic_global_properties' | relative_url }}), we can retrieve the current state information using `curl`:

```bash
curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_dynamic_global_properties", "params":[], "id":1}' https://api.hive.blog
```
