# getblocktemplate - Dogecoin

Example code for the getblocktemplate JSON-RPC method. Complete guide on how to use getblocktemplate JSON-RPC in GetBlock Web3 documentation.

This method returns the data a miner needs to construct a candidate block. It is used by mining software rather than by wallet or payment integrations.

## Parameters

| Parameter         | Type   | Required | Description                                                    |
| ----------------- | ------ | -------- | -------------------------------------------------------------- |
| template\_request | object | No       | Request object with `mode`, `capabilities`, and `rules` fields |

| result.target            | string       | Proof-of-work target the block must meet                |

{% hint style="info" %}
Dogecoin is merge-mined with Litecoin, so production mining uses an AuxPoW workflow rather than solving this template directly. The template is still returned in the standard shape.
{% endhint %}

## Use Cases

* **Mining Software**: Build a candidate block to work on
* **Pool Operation**: Distribute work to connected miners
* **Subsidy Inspection**: Read the current coinbase value
