A user can choose to become a node operator by staking 4 ETH per validator BLS public key within a designated LSD Network. Node runners familiar with Ethereum staking will know about the risk of capital loss if the node is not run correctly. In the case of LSD, poor node performance can be reported to the underlying Stakehouse protocol. For more information see this article about reporting and SLOT.
Each node operator is associated with a unique smart wallet which can be used to initiate staking of multiple validators. A smart wallet can contain multiple validators and the node operator associated with the smart wallet will have to supply 4 ETH for every validator associated with the smart wallet. The creation of the smart wallet requires at least one BLS public key provided by the node operator and ETH depending on the number of validators to be staked from the smart wallet.
Once the staking pools have collected 28 ETH, the node runner can trigger the stake function which will send 24 ETH from the Protected Staking pool and 4 ETH from the MEV and Fees Staking pool to the Ethereum deposit contract
