Lodestar/ChainSafe team here.
We already diversified 30% of our beacon nodes to run Lodestar + Nethermind. We’ve started testing Lodestar + Besu, another popular combination with solo stakers we’ve spoken to. We are aiming to have transitioned to 10% Geth, 45% Nethermind and 45% Besu for the mainnet Deneb fork. We wanted to maintain a small portion of Lodestar + Geth as a primary for continuous comparison and compatibility oversight with Lodestar. As other execution clients are more stabilized, we will aim to include them as well.
