Telller's network of distributed cloud nodes operate as Proof of Cloud (POC) consesus 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 looks like the following:
The three core components of the distributed cloud network are:
The Teller Subgraph
Teller Contract Event Listener
Teller Web2
Teller's Subgraph listens for events emitted through interactions with the protocol's deployed smart contracts, and then parses them to a graphQL service. The instructions and repo can be found in the link below:
Contract event listener (CEL) will read and store all the data that the subgraph generates into a local postgres database to be consumed by the node.
Web2 is the primary web service endpoint of the node, which handles the user requests via a RPC JSON v2.0 service.
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:
