Magento2 : display static blocks in home page

You can do it in 2 ways.

From cms page add block to homage:

{{block class="Magento\Cms\Block\Block" block_id="block_identifier"}}

From Xml File:

<referenceContainer name="content">
    <block class="Magento\Cms\Block\Block" name="block_identifier">
        <arguments>
            <argument name="block_id" xsi:type="string">block_identifier</argument>
        </arguments>
    </block>
</referenceContainer>

Hope this helps you

Keep below XML in your cms_index_index.xml file and check-in front,

You have to keep the same block_identifier for both static blocks.

You have to keep static block name as unique,

  <referenceContainer name="content.bottom">
        <block class="Magento\Cms\Block\Block" name="block_identifier">
            <arguments>
                <argument name="block_id" xsi:type="string">block1</argument>
            </arguments>
        </block>

        <block class="Magento\Cms\Block\Block" name="block_identifier-second" after="-">
            <arguments>
                <argument name="block_id" xsi:type="string">block2</argument>
            </arguments>
        </block>
   </referenceContainer>

Replace block1 and block2 with your static block id in above XML code.
