This article mainly explains "what are NEO nodes?" Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let Xiaobian take you to learn "what NEO nodes have"!

Full nodes are nodes that store all the data of NEO blockchain and are connected to the blockchain network through P2P. In the blockchain network, all full nodes are equal, acting as both clients and servers.

NEO has two full-node programs:

NEO-GUI: For ordinary users, provides a graphical interface with all functions except consensus.

NEO-CLI: For developers, it provides a command-line interface with some basic functions of wallet operation. In addition, it also provides APIs to reach consensus with other nodes and participate in block generation.

Port Description/NEO-CLI Security Policy

If you want external programs to access the node's API, you need to open firewall ports. Here are port instructions.

NOTE

Mandatory: Whitelists or firewalls must be used to block requests from external servers, otherwise there is a significant security risk.

NEO-CLI itself does not provide remote wallet opening and closing function, and there is no verification process when opening wallet. Therefore, security policies are made by users according to their own circumstances. For exchanges, since wallets are always open to process user withdrawals, wallets must run on separate servers from a security perspective, and port firewalls must be configured as shown in the table below.
