title: Testnets
|
|
description: An overview of public test networks that you can test Ocean Protocol applications against.
|
|
---
|
|
|
|
You can test an Ocean Protocol application (such as a marketplace) against the test networks (testnets) described below. This page is a brief overview of those testnets. The [tutorials](/tutorials/) cover more details (e.g. how to connect to specific ones).
|
|
|
|
## The Kovan Testnet
|
|
|
|
The [Kovan Testnet](https://github.com/kovan-testnet/proposal) (or just "Kovan") is a public Ethereum Testnet operated by members of the Ethereum community.
|
|
The Ocean Protocol keeper contracts are deployed to the Kovan Testnet.
|
|
|
|
For developers building on Ocean Protocol, we recommend starting with a [Spree Testnet](#a-spree-testnet-for-local-development).
|
|
|
|
### Kovan Blockchain Explorers
|
|
|
|
There are some Kovan blockchain explorers, e.g. [Etherscan for Kovan](https://kovan.etherscan.io/) and [BlockScout for Kovan](https://blockscout.com/eth/kovan). You can use those to check the status of a transaction, the balance of an account, and more.
|
|
|
|
### Ocean Components Connected to Kovan
|
|
|
|
There is a [Secret Store](/concepts/components/#secret-store) connected to the Kovan Testnet for use by Ocean Protocol projects (including your projects). It's operated by BigchainDB GmbH. Its URL is:
|
|
|
|
[https://secret-store-kovan.dev-ocean.com/](https://secret-store-kovan.dev-ocean.com/)
|
|
|
|
Aside from the Secret Store, there is no other Ocean Protocol software component (e.g. Aquarius) that is live, connected to the Kovan Testnet, and operated by BigchainDB GmbH.
|
|
|
|
### Using Barge with Kovan
|
|
|
|
If you run [Barge](https://github.com/oceanprotocol/barge) with the the `--local-kovan-node` option, then Barge will run a Kovan node on your local machine (along with everything else Barge runs). There are many blocks in the Kovan Testnet's blockchain, so it can take a long time for your local Kovan node to sync, i.e. to download a local copy of all the blocks. **In the meantime, the local Kovan node won't be able to do certain things.**
|
|
|
|
## The Nile Testnet
|
|
|
|
_Also known as the Beta Network or Nile Beta Network. Formerly called the Ocean POA Testnet._
|
|
|
|
The Nile Testnet is similar to the Kovan Testnet, except all the nodes are operated by BigchainDB GmbH.
|
|
|
|
For developers building on Ocean Protocol, we recommend starting with a [Spree Testnet](#a-spree-testnet-for-local-development).
|
|
|
|
### Connect to the Nile Testnet
|
|
|
|
See the [tutorial page about connecting to Ocean-related networks](/tutorials/connect-to-networks/#connect-to-the-nile-testnet).
|
|
|
|
### Nile Blockchain Explorers
|
|
|
|
There is a Nile blockchain explorer at [https://submarine.dev-ocean.com/](https://submarine.dev-ocean.com/). You can use it to check the status of a transaction, the balance of an account, and more. It uses the following symbols for Nile Ether and Nile Ocean Tokens:
|
|
|
|
| Cryptocurrency | Symbol used |
|
|
| ----------------- | ---------------- |
|
|
| Nile Ether | POA |
|
|
| Nile Ocean Tokens | OCEAN or SBT-OCN |
|
|
|
|
### Ocean Components Connected to Nile
|
|
|
|
There are several Ocean Protocol software components that are live, connected to the Nile Testnet, and operated by BigchainDB GmbH:
|
|
|
|
- Secret Store at [https://secret-store.dev-ocean.com](https://secret-store.dev-ocean.com)
|
|
- Aquarius at [https://nginx-aquarius.dev-ocean.com](https://nginx-aquarius.dev-ocean.com)
|
|
- Brizo at [https://nginx-brizo.dev-ocean.com](https://nginx-brizo.dev-ocean.com)
|
|
- Jupyter Hub at [https://mantaray.dev-ocean.com](https://mantaray.dev-ocean.com)
|
|
- [Token Bridge Frontend](https://github.com/oceanprotocol/bridge-ui) (for a token bridge between Nile and Kovan) at [https://token-bridge.dev-ocean.com](https://token-bridge.dev-ocean.com)
|
|
- Commons Marketplace at [https://commons.oceanprotocol.com](https://commons.oceanprotocol.com)
|
|
- Faucet Server at [faucet.nile.dev-ocean.com](https://faucet.nile.dev-ocean.com)
|
|
|
|
> Internal note: The private "atlantic" repo documents the internal details of the Nile Testnet in `networks/nile/README.md`.
|
|
|
|
### Using Barge with Nile
|
|
|
|
If you run [Barge](https://github.com/oceanprotocol/barge) with the `--local-nile-node` option, then Barge will run a Nile node on your local machine (along with everything else Barge runs). There might be many blocks in the Nile Testnet's blockchain, so it might take a long time for your local Nile node to sync, i.e. to download a local copy of all the blocks. **In the meantime, the local Nile node won't be able to do certain things.**
|
|
|
|
## A Spree Testnet (for Local Development)
|
|
|
|
By default, [Barge](https://github.com/oceanprotocol/barge) will deploy a local "Spree Testnet" on your machine: a local testnet not connected to any external public testnet.
|
|
|
|
When running a Spree Testnet, you can connect to a node at RPC URL [http://localhost:8545](http://localhost:8545) (called "Localhost 8545" in MetaMask).
|
|
|
|
Spree Testnet details can be found in the [Barge README.md file](https://github.com/oceanprotocol/barge#spree-network). You can configure the Spree nodes by editing the files in the `barge/networks/spree/` directory.
|
|
|
|
> Note: Spree testnets are named after the Spree River, the main river flowing through Berlin, Germany, where many Ocean Protocol developers are located.
|
|
|
|
## A Ganache-Based Testnet (for Local Development)
|
|
|
|
A local testnet similar to Spree but launched by using the `--local-ganache-node` option with Barge.
|
|
|
|
Note: You shouldn't use a Ganache-Based Testnet unless you know why you're doing so. For example, a Ganache-based testnet can be used to test some smart contracts, but it can't be used with a Secret Store.
