# Satellite Network

All availability challenges in ICN require the use of both ScalerNodes and HyperNodes to submit reports on the Satellite Network. By leveraging the Satellite Network, reports are ensured to be accessible off-chain for a predetermined duration, after which all data is securely deleted.

The availability reports currently include the following information:

1. Originator: Type of node submitting the report (ScalerNode or HyperNode).
2. Originator version: Software version running on the originator node.
3. Era ID: The era number in which the challenge occurred.
4. ScalerNode ID: The unique identifier of the ScalerNode that initiated the challenge.
5. HyperNode ID: The unique identifier of the HyperNode that responded to the challenge.
6. Signatures: A record  of the signatures from both the ScalerNode and HyperNode, including their corresponding public keys.
