## Ocean Network
|
|
|
|
An _Ocean network_ is any EVM-compatible network where [Ocean smart contracts](https://github.com/oceanprotocol/ocean-contracts) are deployed. These include:
|
|
|
|
- [Ethereum Mainnet](https://www.ethereum.org)
|
|
- Ethereum [test networks](/concepts/testnets/)
|
|
|
|
## Data Service, Data Asset, Datatoken
|
|
|
|
A _data service_ may serve up a dataset or a compute service like Compute-to-Data. It's characterized by a url.
|
|
|
|
Each _data asset_ is represented by an ERC20 _datatoken_.
|
|
|
|
You can access a data service if you send 1.0 datatokens to the Provider.
|
|
|
|
## Data Publisher, Provider
|
|
|
|
A _data publisher_ is someone who has data services that they want to sell. An example is an almond distributor with 30 years of data about almond sales.
|
|
|
|
A _Provider_ is a service that mediates access to assets on behalf of data owners or data service providers.
|
|
|
|
> Initially, most data publishers will also be Providers.
|
|
|
|
## Data Consumer
|
|
|
|
A _data consumer_ is someone who buys a data asset, then consumes it by interacting with the _Provider_.
|
|
|
|
## Data Market
|
|
|
|
A data market is a service where publishers can list what assets they have, and consumers can see what's available then buy it.
|
|
|
|
## Metadata
|
|
|
|
Metadata is information about the data asset. In Ocean, metadata is stored on-chain, but marketplaces may have a local cache for faster search.
