# Network Node

In the context of blockchain networks, nodes are the fundamental building blocks responsible for maintaining and verifying the network’s integrity. DataDance operates across two distinct network environments: the Testnet and the Mainnet.



### Testnet:

The testnet is a sandbox environment where developers and users can experiment with new features and smart contracts without risking real assets. Transactions and operations conducted on the testnet do not affect the main blockchain and typically use test tokens. This allows for extensive testing, bug fixes, and security audits before deploying code to the production environment.



### Mainnet:

The mainnet is the production version of the network where actual transactions take place, involving real assets and users. Once fully tested on the testnet, features and applications are deployed to the mainnet, where they function within the live blockchain ecosystem. The mainnet ensures data integrity, secure transactions, and performance stability as it represents the fully operational version of the blockchain.



DataDance provides both environments to support ongoing development, testing, and real-world use, offering flexibility and security in blockchain operations.
