# LN-ExEx Data Protocol

### About

The `LN-ExEx` data protocol on Arweave is responsible for archiving Load Network's full block data, which is posted to Arweave using the [Arweave Data Uploader Execution Extension (ExEx).](/load-network-exex/load-network-exexes/arweave-data-uploader.md) 

{% hint style="warning" %}
After the rebrand from WeaveVM to Load Network, all the data protocol tags have changed the "\*WeaveVM\*" onchain term (Arweave tag) to "\*LN\*"
{% endhint %}

### Protocol Specifications

The data protocol transactions follow the ANS-104 data item specifications. Each Load Network block is posted on Arweave, after borsh-brotli encoding, with the following tags:

| Tag Name         | Tag Value                  | Description                                                                                          |
