# Architecture Overview
|
|
||||||
|
|
||||||
Embark on an exploration of the innovative realm of Ocean Protocol, where data flows seamlessly and AI achieves new heights. Dive into the intricately layered architecture that converges data and services, fostering a harmonious collaboration. Let us delve deep and uncover the profound design of Ocean Protocol.🐬
|
|
||||||
|
|
||||||
<figure><img src="../.gitbook/assets/OP High Level Architecture.jpg" alt=""><figcaption><p>Overview of the Ocean Protocol Architecture</p></figcaption></figure>
|
|
||||||
|
|
||||||
### Layer 1: The Foundational Blockchain Layer
|
|
||||||
|
|
||||||
At the core of Ocean Protocol lies the robust [Blockchain Layer](contracts/). Powered by blockchain technology, this layer ensures secure and transparent transactions. It forms the bedrock of decentralized trust, where data providers and consumers come together to trade valuable assets. 
|
|
||||||
|
|
||||||
The [smart contracts](contracts/) are deployed on the Ethereum mainnet and other compatible [networks](../discover/networks/). The libraries encapsulate the calls to these smart contracts and provide features like publishing new assets, facilitating consumption, managing pricing, and much more. To explore the contracts in more depth, go ahead to the [contracts](contracts/) section.
|
|
||||||
|
|
||||||
### Layer 2: The Empowering Middle Layer
|
|
||||||
|
|
||||||
Above the smart contracts, you'll find essential [libraries](architecture.md#libraries) employed by applications within the Ocean Protocol ecosystem, the [middleware components](architecture.md#middleware-components), and [Compute-to-Data](architecture.md#compute-to-data).
|
|
||||||
|
|
||||||
#### Libraries
|
|
||||||
|
|
||||||
These libraries include [Ocean.js](broken-reference), a JavaScript library, and [Ocean.py](ocean.py/), a Python library. They serve as powerful tools for developers, enabling integration and interaction with the protocol.
|
|
||||||
|
|
||||||
1. [Ocean.js](broken-reference): Ocean.js is a JavaScript library that serves as a powerful tool for developers looking to integrate their applications with the Ocean Protocol ecosystem. Designed to facilitate interaction with the protocol, Ocean.js provides a comprehensive set of functionalities, including data tokenization, asset management, and smart contract interaction. Ocean.js simplifies the process of implementing data access controls, building dApps, and exploring data sets within a decentralized environment. 
|
|
||||||
2. [Ocean.py](ocean.py/): Ocean.py is a Python library that empowers developers to integrate their applications with the Ocean Protocol ecosystem. With its rich set of functionalities, Ocean.py provides a comprehensive toolkit for interacting with the protocol. Developers and [data scientists](../data-science/) can leverage Ocean.py to perform a wide range of tasks, including data tokenization, asset management, and smart contract interactions. This library serves as a bridge between Python and the decentralized world of Ocean Protocol, enabling you to harness the power of decentralized data.
|
|
||||||
|
|
||||||
#### Middleware components
|
|
||||||
|
|
||||||
Additionally, in supporting the discovery process, middleware components come into play:
|
|
||||||
|
|
||||||
1. [Aquarius](aquarius/): Aquarius acts as a metadata cache, enhancing search efficiency by caching on-chain data into Elasticsearch. By accelerating metadata retrieval, Aquarius enables faster and more efficient data discovery.
|
|
||||||
2. [Provider](provider/): The Provider component plays a crucial role in facilitating various operations within the ecosystem. It assists in asset downloading, handles [DDO](ddo-specification.md) (Decentralized Data Object) encryption, and establishes communication with the operator-service for Compute-to-Data jobs. This ensures secure and streamlined interactions between different participants.
|
|
||||||
3. [Subgraph](subgraph/): The Subgraph is an off-chain service that utilizes GraphQL to offer efficient access to information related to datatokens, users, and balances. By leveraging the subgraph, data retrieval becomes faster compared to an on-chain query. This enhances the overall performance and responsiveness of applications that rely on accessing this information.
|
|
||||||
|
|
||||||
#### Compute-to-Data
|
|
||||||
|
|
||||||
[Compute-to-Data](compute-to-data/) (C2D) represents a groundbreaking paradigm within the Ocean Protocol ecosystem, revolutionizing the way data is processed and analyzed. With C2D, the traditional approach of moving data to the computation is inverted, ensuring privacy and security. Instead, algorithms are securely transported to the data sources, enabling computation to be performed locally, without the need to expose sensitive data. This innovative framework facilitates collaborative data analysis while preserving data privacy, making it ideal for scenarios where data owners want to retain control over their valuable assets. C2D provides a powerful tool for enabling secure and privacy-preserving data analysis and encourages collaboration among data providers, ensuring the utilization of valuable data resources while maintaining strict privacy protocols.
|
|
||||||
|
|
||||||
### Layer 3: The Accessible Application Layer
|
|
||||||
|
|
||||||
Here, the ocean comes alive with a vibrant ecosystem of dApps, marketplaces, and more. This layer hosts a variety of user-friendly interfaces, applications, and tools, inviting data scientists and curious explorers alike to access, explore, and contribute to the ocean's treasures. 
|
|
||||||
|
|
||||||
Prominently featured within this layer is [Ocean Market](../user-guides/using-ocean-market.md), a hub where data enthusiasts and industry stakeholders converge to discover, trade, and unlock the inherent value of data assets. Beyond Ocean Market, the Application Layer hosts a diverse ecosystem of specialized applications and marketplaces, each catering to unique use cases and industries. Empowered by the capabilities of Ocean Protocol, these applications facilitate advanced data exploration, analytics, and collaborative ventures, revolutionizing the way data is accessed, shared, and monetized. 
|
|
||||||
|
|
||||||
### Layer 4: The Friendly Wallets
|
|
||||||
|
|
||||||
At the top of the Ocean Protocol ecosystem, we find the esteemed [Web 3 Wallets](../discover/wallets/), the gateway for users to immerse themselves in the world of decentralized data transactions. These wallets serve as trusted companions, enabling users to seamlessly transact within the ecosystem, purchase and sell data NFTs, and acquire valuable datatokens. For a more detailed exploration of Web 3 Wallets and their capabilities, you can refer to the [wallet intro page](../discover/wallets/).
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
With the layers of the architecture clearly delineated, the stage is set for a comprehensive exploration of their underlying logic and intricate design. By examining each individually, we can gain a deeper understanding of their unique characteristics and functionalities.

### Path to Sustainability
|
One transaction may have fees going to several entities, such as the market where the asset was published, or the Ocean Community. Here are all of them:
|
||||||
|
|
||||||
Ocean Protocol achieves sustainability via the [Web3 sustainability loop](https://blog.oceanprotocol.com/the-web3-sustainability-loop-b2a4097a36e).
|
* Publish Market: the market where the asset was published.
|
||||||
|
* Consume Market: the market where the asset was consumed.
|
||||||
|
* Provider: the entity facilitating asset consumption. May serve up data, run compute, etc.
|
||||||
|
* Ocean Community: Ocean Community Wallet.
|
||||||
|
|
||||||
* The project grows and improves through the efforts of OceanDAO grant recipients.
|
### Publish fee
|
||||||
* The OceanDAO votes to decide which proposals receive grants.
|
|
||||||
* Grant funds are sourced from the Ocean Protocol community treasury.
|
|
||||||
* The Ocean Protocol community collects fees when users interact with the protocol, thus completing the sustainability loop.
|
|
||||||
|
|
||||||
### Fee types
|
When you publish an asset on the Ocean marketplace, there are currently no charges for publishing fees :tada:
|
||||||
|
|
||||||
|
However, if you're building a custom marketplace, you have the flexibility to include a publishing fee by adding an extra transaction in the publish flow. Depending on your marketplace's unique use case, you, as the marketplace owner, can decide whether or not to implement this fee. We believe in giving you the freedom to tailor your marketplace to your specific needs and preferences.

|
|
||||||
#### Publish fee
|
### Consume(aka. Order) fee
|
||||||
|
|
||||||
Publish fees can be charged to a publisher when they publish an asset.
|
When a user exchanges a [datatoken](datatokens.md) for the privilege of downloading an asset or initiating a compute job that utilizes the asset, consume fees come into play. These fees are associated with accessing an asset and include:
|
||||||
|
|
||||||
Currently, the Ocean marketplace does not charge a publishing fee. Custom marketplaces can charge a publishing fee by adding an extra transaction in the publish flow.
|
1. **Publisher Market** Consumption Fee 
|
||||||
|
* Defined during the ERC20 [creation](https://github.com/oceanprotocol/contracts/blob/b937a12b50dc4bdb7a6901c33e5c8fa136697df7/contracts/templates/ERC721Template.sol#L334).
|
||||||
|
* Defined as Address, Token, Amount. The amount is an absolute value(not a percentage).
|
||||||
|
* A marketplace can charge a specified amount per order. 
|
||||||
|
* Eg: A market can set a fixed fee of 10 USDT per order, no matter what pricing schemas are used (fixedrate with ETH, BTC, dispenser, etc).
|
||||||
|
2. **Consume Market** Consumption Fee 
|
||||||
|
*  A market can specify what fee it wants on the order function.
|
||||||
|
3. **Provider Consumption** Fees 
|
||||||
|
* Defined by the [Provider](../provider/) for any consumption.
|
||||||
|
* Expressed in: Address, Token, Amount (absolute), Timeout.
|
||||||
|
* You can retrieve them when calling the initialize endpoint. 
|
||||||
|
* Eg: A provider can charge a fixed fee of 10 USDT per consume, irrespective of the pricing schema used (e.g., fixed rate with ETH, BTC, dispenser).
|
||||||
|
4. **Ocean Community** Fee
|
||||||
|
* Ocean's smart contracts collect **Ocean Community fees** during order operations. These fees are reinvested in community projects and distributed to the veOcean holders through Data Farming.
|
||||||
|
* This fee is set at the [smart contract](https://github.com/oceanprotocol/contracts/blob/main/contracts/communityFee/OPFCommunityFeeCollector.sol) level.
|
||||||
|
* It can be updated by Ocean Protocol Foundation. See details in our [smart contracts](https://github.com/oceanprotocol/contracts/blob/main/contracts/pools/FactoryRouter.sol#L391-L407).
|
||||||
|
|
||||||
Based on the use case of the marketplace, the marketplace owner can decide if this fee should be charged or not.

#### Ocean Community fee
|
</details>
|
||||||
|
|
||||||
Ocean's smart contracts collect **Ocean Community fees** during order operations. These fees are reinvested in community projects and distributed to the veOcean holders through Data Farming.
|
Each of these fees plays a role in ensuring fair compensation and supporting the Ocean community. 
|
||||||
|
|
||||||
The provider Ocean Community order fee is 0.03 DT per order operation.

|
||||||
These fees can be updated by the Ocean Protocol Foundation.
|
### Provider fee
|
||||||
|
|
||||||
#### Provider fee
|
[Providers](../provider/) facilitate data consumption, initiate compute jobs, encrypt and decrypt DDOs, and verify user access to specific data assets or services. 
|
||||||
|
|
||||||
Provider is a component of Ocean Protocol's ecosystem that facilitates data consumption, starts compute jobs, encrypts DDOs, and decrypts DDOs. The provider also validates if the user can access a particular data asset or service. To learn more about Provider, click here.
|
Provider fees serve as [compensation](../community-monetization.md#3.-running-your-own-provider) to the individuals or organizations operating their own provider instances when users request assets. 
|
||||||
|
|
||||||
Provider fees are paid to the individual or organization running their Provider instance when the user orders an asset. These fees can be set to an absolute amount, not as a percentage. The provider can also specify which token the fees must be paid in - they don't have to be the same token used in the consuming market.
|
* Defined by the [Provider](../provider/) for any consumption.
|
||||||
|
* Expressed in: Address, Token, Amount (absolute), Timeout.
|
||||||
|
* You can retrieve them when calling the initialize endpoint. 
|
||||||
|
* These fees can be set as a **fixed amount** rather than a percentage. 
|
||||||
|
* Providers have the flexibility to specify the token in which the fees must be paid, which can differ from the token used in the consuming market.
|
||||||
|
* Provider fees can be utilized to charge for [computing](../compute-to-data/) resources. Consumers can select the desired payment amount based on the compute resources required to execute an algorithm within the [Compute-to-Data](../compute-to-data/) environment, aligning with their specific needs.
|
||||||
|
* Eg: A provider can charge a fixed fee of 10 USDT per consume, irrespective of the pricing schema used (e.g., fixed rate with ETH, BTC, dispenser).
|
||||||
|
* Eg: A provider may impose a fixed fee of 15 DAI to reserve compute resources for 1 hour, enabling the initiation of compute jobs.
|
||||||
|
|
||||||
Provider fees can also be used to charge for computing resources. Based on the compute resources needed to run an algorithm in the Compute-to-Data environment, a consumer can choose the amount to pay according to their needs.
|
These fees play a crucial role in incentivizing individuals and organizations to operate provider instances and charge consumers based on their resource usage. By doing so, they contribute to the growth and sustainability of the Ocean Protocol ecosystem.

# Fees
|
|
||||||
|
|
||||||
### Path to Sustainability
|
|
||||||
|
|
||||||
Ocean Protocol achieves sustainability via the [Web3 sustainability loop](https://blog.oceanprotocol.com/the-web3-sustainability-loop-b2a4097a36e).
|
|
||||||
|
|
||||||
* The project grows and improves through the efforts of OceanDAO grant recipients.
|
|
||||||
* The OceanDAO votes to decide which proposals receive grants.
|
|
||||||
* Grant funds are sourced from the Ocean Protocol community treasury.
|
|
||||||
* The Ocean Protocol community collects fees when users interact with the protocol, thus completing the sustainability loop.
|
|
||||||
|
|
||||||
### Fee types
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
#### Publish fee
|
|
||||||
|
|
||||||
Publish fees can be charged to a publisher when they publish an asset.
|
|
||||||
|
|
||||||
Currently, the Ocean marketplace does not charge a publishing fee. Custom marketplaces can charge a publishing fee by adding an extra transaction in the publish flow.
|
|
||||||
|
|
||||||
Based on the use case of the marketplace, the marketplace owner can decide if this fee should be charged or not.
|
|
||||||
|
|
||||||
#### Consume(aka. Order) fee
|
|
||||||
|
|
||||||
Consume fees are charged when a user holding a datatoken exchanges it for the right to download an asset or to start a compute job that uses the asset.
|
|
||||||
|
|
||||||
These are the fees that are applied whenever a user pays to access an asset:
|
|
||||||
|
|
||||||
* Consume Market Consumption Fee
|
|
||||||
* Publisher Market Consumption Fee
|
|
||||||
* Provider Consumption Fees
|
|
||||||
* [Ocean Community Fee](fees.md#ocean-community-fee)
|
|
||||||
|
|
||||||
#### Ocean Community fee
|
|
||||||
|
|
||||||
Ocean's smart contracts collect **Ocean Community fees** during order operations. These fees are reinvested in community projects and distributed to the veOcean holders through Data Farming.
|
|
||||||
|
|
||||||
The provider Ocean Community order fee is 0.03 DT per order operation.
|
|
||||||
|
|
||||||
These fees can be updated by the Ocean Protocol Foundation.
|
|
||||||
|
|
||||||
#### Provider fee
|
|
||||||
|
|
||||||
Provider is a component of Ocean Protocol's ecosystem that facilitates data consumption, starts compute jobs, encrypts DDOs, and decrypts DDOs. The provider also validates if the user can access a particular data asset or service. To learn more about Provider, click here.
|
|
||||||
|
|
||||||
Provider fees are paid to the individual or organization running their Provider instance when the user orders an asset. These fees can be set to an absolute amount, not as a percentage. The provider can also specify which token the fees must be paid in - they don't have to be the same token used in the consuming market.
|
|
||||||
|
|
||||||
Provider fees can also be used to charge for computing resources. Based on the compute resources needed to run an algorithm in the Compute-to-Data environment, a consumer can choose the amount to pay according to their needs.
|
|
||||||
|
|
||||||
These fees incentivize individuals and organizations to run their provider instances and charge consumers according to resource usage.

# Get data NFT information
|
|
||||||
|
|
||||||
Now that you are familiar with the process of retrieving a list of data NFTs 😎, let's explore how to obtain more specific details about a particular NFT through querying. By utilizing the knowledge you have gained, you can customize your GraphQL query to include additional parameters such as the NFT's metadata, creator information, template, or any other relevant data points. This will enable you to delve deeper into the intricacies of a specific NFT and gain a comprehensive understanding of its attributes. With this newfound capability, you can unlock valuable insights and make informed decisions based on the specific details retrieved. So, let's dive into the fascinating world of querying and unravel the unique characteristics of individual data NFTs.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||

# Get datatoken information
|
|
||||||
|
|
||||||
To fetch detailed information about a specific datatoken, you can utilize the power of GraphQL queries. By constructing a query tailored to your needs, you can access key parameters such as the datatoken's ID, name, symbol, total supply, creator, and associated dataTokenAddress. This allows you to gain a deeper understanding of the datatoken's characteristics and properties. With this information at your disposal, you can make informed decisions, analyze market trends, and explore the vast potential of datatokens within the Ocean ecosystem. Harness the capabilities of GraphQL and unlock a wealth of datatoken insights.
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
The result of the following GraphQL query returns the information about a particular datatoken. Here, `0x122d10d543bc600967b4db0f45f80cb1ddee43eb` is the address of the datatoken.
|
|
||||||
|
|

# Get data NFTs
|
|
||||||
|
|
||||||
If you are already familiarized with the concept of NFTs, you're off to a great start. However, if you require a refresher, we recommend visiting the [data NFTs and datatokens page](../contracts/datanft-and-datatoken.md) for a quick overview. 
|
|
||||||
|
|
||||||
Now, let us delve into the realm of utilizing the subgraph to extract a list of data NFTs that have been published using the Ocean contracts. By employing GraphQL queries, we can seamlessly retrieve the desired information from the subgraph. You'll see how simple it is :sunglasses:
|
|
||||||
|
|
||||||
You'll find below an example of a GraphQL query that retrieves the first 10 data NFTs from the subgraph. The GraphQL query is structured to access the "nfts" route, extracting the first 10 elements. For each item retrieved, it retrieves the "id," "name," "symbol," "owner," "address," "assetState," "tx," "block," and "transferable" parameters.
|
|
||||||
|
|
||||||
There are several options available to see this query in action. Below, you will find three:
|
|
||||||
|
|
||||||
1. Run the GraphQL query in the GraphiQL interface.
|
|
||||||
2. Execute the query in Python by following the code snippet.
|
|
||||||
3. Execute the query in JavaScript by clicking on the "Run" button of the Javascript tab.
|
|
||||||
|
|
||||||
_PS: In these examples, the query is executed on the Ocean subgraph deployed on the mainnet. If you want to change the network, please refer to_ [_this table_](broken-reference)_._

# Get fixed-rate exchanges
|
|
||||||
|
|
||||||
Having gained knowledge about fetching lists of data NFTs and datatokens and extracting specific information about each, let's now explore the process of retrieving the information of fixed-rate exchanges. A fixed-rate exchange refers to a mechanism where data assets can be traded at a predetermined rate or price. These exchanges offer stability and predictability in data transactions, enabling users to securely and reliably exchange data assets based on fixed rates. If you need a refresher on fixed-rate exchanges, visit the [asset pricing](../contracts/pricing-schemas.md#fixed-pricing) page.
