Rocket Pool is a decentralised Ethereum staking pool offering up to 4.33% APR for ETH staking. Users can become a part of the Rocket Pool network either by joining its decentralized node operator network or by operating their own nodes with just 16 ETH (instead of the usual 32 ETH). The idea behind Rocket Pool is to make ETH staking accessible to everyone, regardless of their investment size or technological expertise. It accomplishes this by enabling the secure staking of ETH through a network of decentralized autonomous nodes, backed by RPL collateral.
