The service is responsible for all the business logic, concerning flow of tokens in Stoa: Data Exchange Platform within Prometeus ecosystem. When any business transaction is executed, billing service distributes the tokens from the payer to recipients.

When data is beeing uploaded to the Storage, the service transfers tokens from the Data Validator to the Service Node (it passes tokens to the Storage via tokenswap).

When data is beeing purchased, the service distributes tokens recieved from the Data Mart between Data Validator and Data Owner.

Each transaction is stored in a Plasma - tree-like structure of numerous chains (able to handle more transactions per second) based on the Ethereum blockchain. The essence of Plasma is that its use allows you to save all transactions and display data about it for the user immediately after the transaction, without waiting for confirmation of the Ethereum network. If the transaction is not confirmed, then the plasma repeats it until success is achieved.

For the relevance of plasma data, transactions will be synchronized with the main network of Ethereum every hour. All the transactions received after synchronization will be collected in one transaction, thereby saving gas.

You can see all the transactions via Prometeus Blockchain Explorer: http://178.62.211.224

All the interactions with billing happen through Service node, which is responsible for connecting all the nodes with each other.

Billing deployment is integrated in the standard process of running a Service Node.

In order to run a service node, you need to install:

• Docker. You can find installation instructions on official website.
• Docker-compose, which can be found here.
• If you want to run service-node outside of docker container, you will need NodeJS installed. You can find installations instructions here.

Firstly, you need to clone service-node from repository:

git clone https://github.com/Prometeus-Network/service-node_net.git

After repository is cloned, perform next commands:

git submodule init 
git submodule update

This will download go-ethereum submodule.

To run Service node inside Docker, execute the following command:

docker-compose up --build

If you want to run service node outside docker container, you will need to perform next steps:

• Execute build.sh script. It will build go-ethereum;
• Run npm install. This will install dependencies required for Service node;
• Run npm run c. This command will compile typescript;
• Run npm run start to start the application.
