# Overview

Telller's network of distributed cloud nodes operates as Proof of Cloud (POC) consensus validators for the Teller Protocol. In other words, the nodes act as a data router for the protocol's smart contracts.

The current system architecture resembles the following diagram:

The two core components of the distributed cloud network are:

1. The Teller Subgraph
2. Teller Validator

## Subgraph

Teller's Subgraph listens for events emitted through interactions with the protocol's deployed smart contracts and then parses them to a graphQL service.

## Validator

Validator is the primary web service endpoint of the node, which handles user requests via an RPC JSON v2.0 service.

## Kubernetes

All of these components are deployed and distributed via docker images using kubernetes, which is in turn packaged as a helm chart installation.

The system architecture diagram is as follows:
