# Genesis tests

The aim of the genesis tests is to provide a baseline to test genesis-state initialization and test

if the proposed genesis-validity conditions are working.

There are two handlers, documented individually:

- [`validity`](./validity.md): Tests if a genesis state is valid, i.e. if it counts as trigger to launch.

- [`initialization`](./initialization.md): Tests the initialization of a genesis state based on Eth1 data.

## Background
|

|

The beacon node maintains the state of the beacon chain by communicating with other beacon nodes in the Ethereum 2.0 network. Conceptually, it does not maintain keypairs that participate with the beacon chain.
|
||||
|

The validator client is a conceptually separate entity which utilizes private keys to perform validator related tasks, called "duties", on the beacon chain. These duties include the production of beacon blocks and signing of attestations.
