| Testnets | 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 cover more details (e.g. how to connect to specific ones).
The Kovan Testnet
The Kovan Testnet (or just "Kovan") is a public Ethereum Testnet operated by members of the Ethereum community.
Kovan Blockchain Explorers
There are some Kovan blockchain explorers, e.g. Etherscan for Kovan and BlockScout for 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 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/
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.
The Nile Testnet
Formerly called the Ocean POA Testnet.
The Nile Testnet is similar to the Kovan Testnet, except all the nodes are operated by BigchainDB GmbH.
Connect to the Nile Testnet
See the tutorial page about connecting to Ocean-related networks.
Nile Blockchain Explorers
There is a Nile blockchain explorer at 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
- Aquarius at https://nginx-aquarius.dev-ocean.com
- Brizo at https://nginx-brizo.dev-ocean.com
- Jupyter Hub at https://mantaray.dev-ocean.com
- Token Bridge Frontend (for a token bridge between Nile and Kovan) at https://token-bridge.dev-ocean.com
Internal note: The private "atlantic" repo documents the internal details of the Nile Testnet in
networks/nile/README.md.
A Spree Testnet
When Ocean Protocol developers run Barge with the --local-spree-node option, a "Spree Testnet" is deployed on their local 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 (called "Localhost 8545" in MetaMask).
Spree Testnet details can be found in the Barge README.md file. 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
A local testnet similar to Spree but launched by using the --local-ganache-node option with Barge.
