# Modes
Chainstack supports deploying an Aurora node on the NEAR mainnet in the following modes:
- Full node — a node that stores full blockchain data.
- Archive node — a node that stores full blockchain data and an archive of historical states.
To be a part of the NEAR mainnet, you can deploy either a full node or an archive node.
With a full node, you can query the historical state of the NEAR mainnet at only the latest 5 epochs (opens new window).
To be able to query the historical state of the NEAR mainnet at any block, you need an archive node.
See Aurora JSON-RPC methods (opens new window) that support querying at a block number.
