# LayerZero V1 - Documentation Has Moved!

LayerZero V1 is an omnichain interoperability protocol designed for lightweight message passing across chains. LayerZero provides authentic and guaranteed message delivery with configurable trustlessness.

{% hint style="warning" %}
With the launch of LayerZero V2, our docs site has moved.\
The legacy LayerZero V1 Documentation can now be found at [docs.layerzero.network/v1](https://docs.layerzero.network/v1).
{% endhint %}

### Where can I find more information?

For the message protocol design, check out the [V1 whitepaper](https://layerzero.network/pdf/LayerZero_Whitepaper_Release.pdf) found on the [website](https://layerzero.network). 

If you are looking for a detailed system architecture explanation, check out the architectures section on the [Endpoint](https://docs.layerzero.network/v1/home/concepts/layerzero-endpoint) and the Ultra-Light Node.
