Architectural Overview

As an operator of a Node on the Oasis Network, it is suggested that you have an understanding of the system architecture of the Oasis Network. Here we will provide a high level overview of the Oasis Network's architecture. This overview is used to provide enough guidance to be useful for the purposes of getting started as a Node Operator. For more information, see our whitepaper.

Modular Architecture

The Oasis Network uses a modular architecture similar to that of a Service Oriented Archiecture or a Microservices Architecture. Any given node participates in one of many different committees. These committees each have different responsibilities in the execution of smart contracts on the Oasis Network. The responsibilities of these committees can be mapped to a set of 4 different layers: Consensus, Compute (Confidential and Non-confidential), Storage, and Key Management. For a Node Operator, these layers map distinctly to different classes Nodes and potentially to different hardware.

Networking Protocols

The Oasis Network uses 3 main protocols for communication:


Confidentiality is achieved in the Oasis Network by relying on trusted execution environments (TEEs) to secure the execution of any given smart contract. Initially, the Oasis Network will utilize Intel SGX. As more TEE technologies mature, we expect to support more than TEEs than Intel SGX.
