Rocket Pool Deploys Saturn I Staking Upgrade
Liquid staking protocol Rocket Pool has launched its Saturn I upgrade, a major update designed to further decentralize Ethereum staking participation. The upgrade is the culmination of seven years of development and aims to enhance the protocol's capital efficiency and security. This move positions Rocket Pool to compete for staking allocations from both DeFi strategies and institutional clients.
- The centerpiece of the Saturn I upgrade is the introduction of "Megapools," which halves the capital required for a node operator to 4 ETH, down from the 8 ETH established by the prior Atlas upgrade. Node operators provide 4 ETH per validator, and the protocol matches it with 28 ETH from the liquid staking pool. - This upgrade activates the "RPL fee switch," a significant change to the token's economic model. The switch transitions RPL staker rewards from being funded by token inflation to earning a share of the protocol's fee revenue denominated in ETH. - Lowering the bond to 4 ETH aims to solve for "node operator availability," a key growth constraint, by making it cheaper to become an operator. This allows the protocol to support a higher demand for its liquid staking token, rETH. - The reduction in operator bond is a continuation of Rocket Pool's strategy to increase decentralization. The original requirement was 16 ETH, which was later reduced to 8 ETH in the "Atlas" upgrade before the current 4 ETH minimum. - Rocket Pool's permissionless design, which allows anyone to become a node operator, contrasts with the market leader Lido, which uses a permissioned set of around 30 professional node operators. While Lido dominates market share with approximately 30% of all staked ETH, Rocket Pool competes on decentralization with over 3,500 independent operators. - A mandatory "Smart Node" software update (v1.18.8) was rolled out to all node operators in January 2026 to prepare the network's infrastructure for the Saturn I changes.
