## Testnet Ocean Tokens
-There are Ocean Tokens in several testnets, including the Kovan testnet and Nile testnet. They are just testnet Ocean Tokens (i.e. for testing purposes only) and they aren't interchangeable with Mainnet Ocean Tokens. For more details, see the the [page about Testnets](/concepts/testnets/) and the [tutorials](/tutorials/introduction/).

+title: The Ocean Production Network
+description: An introduction to the Ocean Production Network.

+
+**At the time of writing, there was no live, running, publicly-available Ocean Production Network.**
+
+Ocean Protocol makes use of several EVM networks, including:
+
+- the Ethereum Mainnet (also called the Main Ethereum Network),
+- various [testnets](/concepts/testnets/), and
+- in the future, the Ocean Production Network.
+
+The Ocean Production Network will be an EVM network of nodes ("keepers") running [Parity Ethereum](https://www.parity.io/ethereum/) software. Various Ocean Protocol smart contracts ("keeper contracts") will be deployed to it. It will be used for production use cases. It is also known by other names, including:
+
+- The Main Ocean Network
+- The Ocean Mainnet
+- The Ocean Live Network
+- (among the internal dev team) The Ocean Pacific Network, or just Pacific
+
+"Network" is sometimes shortened to just "Net."
+
+[Ocean Tokens](/concepts/ocean-tokens/) can, in principle, live in any EVM network. The ones sold in the Ocean Protocol token sale were in the Ethereum Mainnet (and still were, at the time of writing). For more information, see [the page about Ocean Tokens](/concepts/ocean-tokens/).

+TODO: search in files for all references to the Ocean Mainnet etc.

-An account's Ether balance might be 7.1 ETH in the Ethereum mainnet, 2.39 ETH in the Kovan testnet, and 0.1 ETH in the Nile testnet. You can't move ETH from one network to another (unless there is a special exchange or bridge set up). The same is true of Ocean Token balances.

Each account has one **private key**, one **public key** and one **address**. The public key and address can be calculated from the private key. You must keep the private key secret because it's what's needed to spend/transfer Ether and Ocean Tokens (or to sign transactions of any kind). You can share the address with others. In fact, if you want someone to send some Ether or Ocean Tokens to an account, you give them the account's address.
