|
|
description: Terminology specific to Ocean Protocol.
|
|
---
|
|
|
|
## Ocean Network
|
|
|
|
Any EVM-compatible network where all[^1] the Ocean Protocol smart contracts ([keeper contracts](https://github.com/oceanprotocol/keeper-contracts)) are deployed. There can be many Ocean networks and you can use the Ocean Protocol in several EVM-compatible networks, including:
|
|
|
|
- the Ethereum Mainnet (also called the Main Ethereum Network)
|
|
- the Ocean [Pacific Main Network](/concepts/pacific-network/)
|
|
- various Ocean [test networks](/concepts/testnets/)
|
|
|
|
## Asset or Data Asset
|
|
|
|
Anything that can be registered with and made available via an Ocean Network. Examples include data sets, trained model parameters, pipelines, and data-cleaning services.
|
|
|
|
## Data Owner or Data Service Provider
|
|
|
|
Someone who has assets that they want to sell (or give away freely). An example is an almond distributor with 30 years of data about almond sales.
|
|
|
|
> Initially, most data owners or data service providers will also be the publishers of their own assets.
|
|
|
|
## Publisher
|
|
|
|
A service which mediates access to assets on behalf of data owners or data service providers.
|
|
|
|
> Initially, most publishers will also be the owners of the assets they publish.
|
|
|
|
## Consumer
|
|
|
|
Someone who wants assets. An example is a data scientist working at an economic think tank.
|
|
|
|
## Marketplace
|
|
|
|
A service where publishers can list what assets they have, and consumers can see what's available then buy it (or get it for free). Every marketplace has a database where they store metadata about the assets they know about (but not the assets themselves). An Ocean network can support many marketplaces.
|
|
|
|
## Verifier
|
|
|
|
A person or a software service that checks some steps in transactions. For example, a verifier might check to see if a cryptographic signature is valid and then get rewarded for doing so.
|
|
|
|
## Service Execution Agreement (SEA) or Service Agreement
|
|
|
|
A contract-like agreement between a publisher, a consumer, and a verifier, specifying what assets are to be delivered (from publisher to consumer), the conditions that must be met, and the rewards for fulfilling the conditions.
|
|
|
|
We published a blog post that explains SEAs in more detail:
