# EVM chain history preservation

{% hint style="warning" %}
Note: This is a roadmap item that is not currently available. We are documenting it here to give developers an idea of potential use cases that can be supported by Hemera Network.
{% endhint %}

Ethereum's history growth is gradually increasing the hardware requirements for running full nodes. For long, Ethereum community has been working on [EIP-4444](https://eips.ethereum.org/EIPS/eip-4444), which requires a solution for history preservation of Ethereum's full nodes. Similar needs will also arise, likely a lot fast, in high performance EVM scenarios, where history grows at 100 \~ 10,000X faster speed. 

As such, an EVM history preservation service designed in a similar architecture as in[ ](/welcome/account-centric-indexing-protocol/example-hemera-use-cases/ethereum-long-term-da.md)[the previous section](/welcome/account-centric-indexing-protocol/example-hemera-use-cases/ethereum-long-term-da.md) can be expanded to meet such needs.
