ParaTime Node

This guide provides an overview of the requirements to become a compute node for a ParaTime connected to the Oasis Network.

About Oasis Network

The Oasis Network has two main components, the consensus layer and the ParaTime Layer.

  1. The consensus layer is a scalable, high-throughput, secure, proof-of-stake consensus run by a decentralized set of validator nodes.
  2. The ParaTime layer hosts many parallel runtimes (ParaTimes), each representing a replicated compute environment with shared state.

Operating ParaTimes

Operating a ParaTime requires the participation of node operators who contribute nodes to the committee in exchange for rewards. ParaTimes can be operated by anyone, and have their own reward system, participation requirements, and structure.

As a node operator you can participate in any number of ParaTimes. While there are a number of ParaTimes under development, below are a few key ParaTimes that you can get involved in today. For operational documentation on running a ParaTime, please see the section on running a ParaTime node for node operators.

Sapphire ParaTime

A confidential EVM-compatible Oasis Foundation developed ParaTime that enables the use of EVM smart contracts on the Oasis network.



  • Fully decentralized with node operators distributed across the world.
  • Oasis ROSE tokens are the native token used in the ParaTime for gas fees.
  • Support for confidential compute.

Mainnet Requirements

For your Sapphire ParaTime node to be eligible to be elected into the Sapphire committee on Mainnet, your entity needs to:

  • Have a validator in the validator set.
  • Have at least 5,000,000.00 ROSE staked/delegated to it.
