# General information

In the first phase, the **EYWA Oracle Network** will operate in **PoA** mode. **EYWA Oracle Network** operation in PoA mode will be supported by more than 100 validator nodes. Each epoch, 40 node-validators will be randomly chosen from the list of network participants, who will validate cross-chain calls during the epoch. The constant rotation of epoch participants (approximately every 12 hours) ensures high network security.

Participation in **PoA mainnet** will be paid - **30,000 EYWA** tokens of additional delegation at the **PoS stage** for each month of successful operation in **PoA mainnet**. Only those **PoA testnet** participant who have successfully passed the testnet phase will be able to join the **PoA mainnet**.

Full requirements for the **PoA mainnet** participants can be found in [**Requirements for PoA mainnet validators**](https://docs.eywa.fi/eywa-oracle-network-will-be-ended-in-april-2024/incentivised-poa-mainnet/requirements-for-poa-mainnet-validators) section.

{% hint style="info" %}
If the validator shows poor validation statistics (for example, low node uptime), the **EYWA** team reserves the right to remove him from the **PoA** validators and take another one in his place.
{% endhint %}

**EYWA Oracle Network** in **PoA mode** will support **CLP** and **CDP** until the **PoS** version is released.

## Composition of mainnet

In mainnet, the composition of the participants will be as follows:

1. **Participants who have successfully passed the testnet phase and applied for participation in the PoA mainnet (>100 nodes).** You can find a participant form to fill out at [this link](https://docs.google.com/forms/d/1v2xEqHwBdjdmXgKrN7M-kwRC5dMJpHfBFSgV3L4eCrQ/viewform?edit_requested=true).
