How to Run a NEO Node: Requirements and Guide

June 7, 2023

To run a NEO node, you need to ensure that your system meets the minimum requirements, configure the node software, and troubleshoot any issues that may arise. This article serves as a comprehensive guide to running a NEO node, covering everything from the minimum system requirements to setting up.

If you are interested in Bitcoin, it is worth exploring how Bitcoin and privacy coins intersect in terms of protecting user anonymity and enhancing transaction privacy.

Minimum System Requirements for Running a NEO Node

Running a NEO node requires a minimum set of system requirements to ensure that the node can perform its essential functions.

These requirements encompass the hardware, network, and software components necessary for the node to connect to the NEO network and validate transactions.

Firstly, let’s consider the hardware requirements for running a NEO node. The CPU and RAM are critical components, as they dictate the processing power and memory capacity of the node. A multi-core CPU with at least 2GHz processing speed and 4GB RAM is the minimum requirement for a NEO node.

However, if you plan on running a full node, which is required for participating in consensus and earning GAS rewards, you should have at least 8GB RAM and a more powerful CPU with 4 cores or more. As for storage, you will need sufficient space to store the blockchain data, which is currently over 11GB and growing.

In addition to the hardware requirements, network requirements are also crucial for running a NEO node.

Bandwidth and latency are the two main factors that determine the network performance of a node. A stable internet connection with a minimum of 10 Mbps upload and download speed is recommended to ensure smooth data transfer.  

Finally, the software requirements for running a NEO node include the operating system and the NEO node software. The node software is available for Windows, macOS, and Linux, and you should select the appropriate version for your operating system.

Additionally, you will need to install the appropriate version of the .NET Core runtime, which is required to run the NEO node software.

In summary, the minimum system requirements for running a NEO node include a CPU with at least 2GHz processing speed, 4GB RAM, sufficient storage space, a stable internet connection with 10 Mbps upload and download speed, and the appropriate version of the NEO node software and .NET Core runtime.  

Setting Up and Configuring a NEO Node

Once you have ensured that your system meets the minimum requirements for running a NEO node, the next step is to set up and configure the node software. This involves downloading and installing the software, configuring the node settings, and syncing the node with the NEO blockchain.

To download the NEO node software, you can visit the official NEO GitHub repository, where you can find the latest version of the software for your operating system. Once you have downloaded the software, you can run the installation wizard to install it on your system.

After the installation is complete, you can configure the node settings to customize the node according to your preferences.

This includes setting the p2p port, which is the port that other nodes will use to connect to your node, and specifying the consensus nodes that your node will connect to for block validation.

You can also configure other settings, such as the RPC port, which enables remote procedure calls to interact with the node, and the maximum number of connections that the node will accept.

Once you have configured the node settings, the next step is to sync the node with the NEO blockchain.

This process involves downloading and verifying all the blockchain data, which can take several hours or even days, depending on your internet connection speed and the amount of data to be downloaded.

During the syncing process, the node will validate the blocks and transactions, and once it has reached the latest block, it will start participating in consensus and validating transactions.

It’s worth noting that the syncing process can be resource-intensive, especially on a low-end system, and may slow down your computer’s performance.

To minimize the impact, you can use the –faststart flag when starting the node, which skips some of the initial validation steps and speeds up the syncing process.


In conclusion, running a NEO node can be a rewarding experience, both financially and technically.

By following the guidelines outlined in this guide, you can set up and configure a NEO node that operates smoothly and contributes to the stability and security of the NEO network.

Whether you are a developer, investor, or blockchain enthusiast, running a NEO node is an essential step in becoming an active participant in the decentralized finance ecosystem.
