# Node Requirements

To ensure a smooth deployment of `AxiomLedger` nodes, please make sure you have the resources specified in this document before actual deployment.

## Hardware Requirements

To run `AxiomLedger` nodes, we recommend the following hardware resources:

* CPU:
  * 8 Cores 16 Threads
  * 2.8GHz or higher
* Memory: 32GB
* Storage: 2T SSD, at least 40K IOPS and 200MiB/s bandwidth
* Network Bandwidth: 1Gbps

The above is the recommended optimal configuration. The minimum hardware requirements are:

* CPU:
* 4 Cores 8 Threads
* Memory: 8GB
* Storage: 500G SSD
* Network Bandwidth: 100Mbps

### Why These Hardware Required

The hardware requirements depend on the transaction speed and storage requirements. The amount of data stored on the `AxiomLedger` blockchain depends on the amount of `transaction` data and `on-chain state` data (such as account data and contract storage data). The current requirements are derived based on a certain amount of usage on the blockchain.

## Network

When running AxiomLedger nodes, you need to open network ports on the nodes to allow other nodes to connect.

Keep the following ports open:

* 4001: P2P port for connecting to other nodes to transmit messages.
* 8881: JSON RPC http port for providing services externally. This port is optional to open.
* 9991: JSON RPC websocket port for providing services externally. This port is optional to open.

Keep the following ports closed:

* 53121/40011: Node metrics exposure ports. Keep them closed to prevent unauthorized node metrics inspection.
