#The Saturn 0 Upgrade

Welcome to Saturn 0! This upgrade aims to improve RPL tokenomics in the short term to unlock protocol growth. If you're a returning or prospective node operator, this page will serve as an introduction to some new and exciting changes to the Rocket Pool protocol.

#ETH only minipools in Saturn 0

• The RPL requirement for new minipools is a thing of the past! Minipools in Saturn 0 do not require RPL stake to be deployed.

• The RPL requirement for new minipools is a thing of the past! Minipools in Saturn 0 do not require RPL stake to be deployed. Node operators can now create minipools with an upfront cost of 8 ETH, which will feature a commission of 10%. In addition, a node operator may optionally stake RPL to qualify for additional rewards and access voting power within the Protocol DAO.

• Nodes with an RPL stake of any size qualify for RPL issuance rewards. This unlocks RPL rewards for Node Operators under the 10% collateral cliff who were previously unqualified for RPL issuance rewards.

• This means nodes with an RPL stake of 0-15% of borrowed ETH receive the maximum APY on RPL. Nodes still earn RPL yield beyond 15% collateral, at a decreasing rate. Feel free to take a look how RPL issuance beyond 15% borrowed ETH is defined in RPIP-30.

#New Commission Structure

We're excited to announce that newly launched Saturn 0 minipools will feature a commission structure ranging from 10% to 14%.

• Nodes without any staked RPL will earn 10% commission (5% from the minipool contract, and 5% from the dynamic commission boost).
• Nodes with staked RPL receive up to an additional 4% dynamic commission boost for staked RPL valued at >= 10% of borrowed ETH.

Note that the dynamic commission boost will be reduced to 0% on the 5th reward snapshot after Saturn 1 is released (leaving only the 5% minipool contract commission). This serves to increase the yield advantage of migrating to megapools.

#Node Operator Guide

If you're interested in running a Rocket Pool node to create your own Ethereum validators, take a look at our Node Operator's guide. This is a very comprehensive guide that goes over all of the considerations involved in node operation, including:

• Deciding to run a node locally at home, or remotely on the cloud
• Selecting the hardware for a local machine, or selecting a remote hosting provider
• Preparing and securing the operating system of your node
• Selecting your Execution and Consensus clients
• Installing Rocket Pool's Smartnode stack
• Creating a new Beacon Chain validator using the Rocket Pool network
• Maintaining and updating your node
• Participating in on-chain governance

Both guides will show you how to practice for free on the Rocket Pool testnet so you can get a feel for everything without risking any of your real-life ETH, and how to stake your real ETH on the Ethereum mainnet once you're comfortable with the process.

When you're ready, select a guide from the options above based on your interests. You are also free to explore the various pages using the sidebar to the left.
