NEAR Networks
NEAR Protocol operates on several networks each operating with their own independent validators and unique state. These networks are as follows: These networks are as follows:
Mainnet​
mainnet
is for production ready smart contracts and live token transfers. Contracts ready for mainnet
should have gone through rigorous testing and independent security reviews if necessary. mainnet
is for production ready smart contracts and live token transfers. Contracts ready for mainnet
should have gone through rigorous testing and independent security reviews if necessary. mainnet
is the only network where state is guaranteed to persist over time (subject to the typical security guarantees of the network's validation process).

Testnet​
testnet
is a public network and the final testing network for nearcore
changes before deployment to mainnet
. testnet
is intended for testing all aspects of the NEAR platform prior to mainnet
deployment. From account creation, mock token transfers, development tooling, and smart contract development, the testnet
environment closely resembles mainnet
behavior. All nearcore
changes are deployed as release candidates on first testnet, before the changes are released on mainnet
. A number of testnet
validators validate transactions and create new blocks. dApp developers deploy their applications on testnet
before deploying on mainnet
. It is important to note that testnet
has its own transactions and states. testnet

Localnet​
localnet
is intended for developers who want to work with the NEAR platform independent of the public blockchain. You will need to generate nodes yourself. localnet
gives you the total control over accounts, economics, and other factors for more advanced use cases (including making changes to nearcore
). For developers, localnet
is the right choice if you prefer to avoid leaking information about your work during the development process. You will need to generate nodes yourself. localnet
