SingularityNET’s Decentralized AI Marketplace Integration with PayPal

The integration of SingularityNET’s decentralized AI marketplace with PayPal represents a significant step in the direction of wide adoption of the platform. It makes it easier for more AI users to leverage the platform, thus increasing the likelihood that data scientists and developers will feel incentivized to consider SingularityNET a viable alternative pathway to monetize their expertise. This integration represents a large opportunity for SingularityNET and our community.

Whatever happens on Blockchain, an event is created, and the Marketplace listens to all events. When there is an event notification, the Marketplace reads the Organization metadata and serviice metadata for example, and retrives the data from the Blockchain and stores them in the local tables, or database.

The Markplace URL page which is designed by the SingularityNET, manages and displays all the information available from Marketplace database. the SingularityNET platform is open and decentralized, the Marketplace is the SingularityNET Foundation’s curated view.

This allows the foundation to adhere to legal requirements of different legislative regions. So whenever an events resides in the local table, they need to be reviewed and approved.

This waiting period is known as Curative process. Only after the successful it has been approved; the service becomes available in the Marketplace.

Note: You can also go to the Marketplace and pay the price through Paypal. I such case, the entire process is managed at the background automatically for you.

The protofile information associated IPFS hash are so complex to understand. But because they are part of the UI, it becomes user-friendly way to build the UI components around a service and host it on SingularityNET platform.

This becomes easy for the user to the Input values that need to be sent and view the computed expected result in the Output field, even without knowing the complexity of the gRPC call and the proto that is associated to the service and so. So when you click the Invoke button the AI service computes the result

This service is integrated with the Multiparty Escrow, allowing the user to pay for the service uisng Paypal, that allows the application to manage.

For example, If you look at the Sample service under the Organization in the Marketplace, you will notice that it shows that you have utilized the free trial service period.

You can choose an option from the following list :

  • Select a Walley
  • General Account Wallet = Metamask

Choose a Metamask.

By selecting this option,yYou are Authorizing SingularityNET to use Metamask. Metamask is a plugin which can be used as an Wallet. It is coming from Ethereum Blockchain, so you can add money, any crypto currency or tokens to this Wallet.

For example if I want to move the money into my account, you need to do a Blockchain Operation. Or need to move money from your account to channel, into my account, which involves some additional charges,

As an AI consumer you can choose to:

  • create a Wallet
  • use a Metamask

The Marketplace offers a free trial version, where registered users can access service(s) for a specified time period. After the expiration time period of the trial version, install an Ethereum browser extension, such as MetaMask.

This extension mediates with the Blockchain on behalf, and helps you in transferring of tokens between wallets, and invoke contracts.

Note: Service metadata is a place where the price of the service is set and it is on the Blockchain.

The service provider needs to publish the details about the service in the Blockchain.

As a consumer, you may go the Blockchain or the Marketplace portal where the services are deployed.

All service metadata details are stored in the the JSON file

  • Create a JSON file - information about the image, service type, description, price of the service, the endpoint and how to make a request.
  • Singularity platform works on gRPC. Whenever you need to call you need a protofile.
  • File management system such as IPFS stores the location of the hash and points to the associated protofile The IPFS can include a file and the same file returns same hash.
