# 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.
