Ether.fi mandates Optimum's mump2p block-propagation software across all 12 node operators, covering 1.4M staked ETH (~3% of total), claiming 2.42x faster block arrival than default GossipSub.

Ethereum liquid staking protocol ether.fi has mandated the use of Optimum's mump2p block-propagation software across all of its node operators, affecting approximately 1.4 million staked ETH—roughly 3% of total ETH staked on the network. The MIT-incubated network reports that mump2p achieves block arrival speeds 2.42 times faster than Ethereum's default GossipSub protocol.
The mandate represents a shift toward specialized infrastructure for one of Ethereum's largest liquid staking providers. By consolidating validator-node software across its operator set, ether.fi aims to standardize block propagation performance and potentially reduce latency across its validator infrastructure. The broader network adoption of such tools could influence how other staking protocols approach their node operator requirements.
What remains unclear is whether other major liquid staking providers will follow ether.fi's lead, and whether widespread adoption of mump2p or similar software would materially impact Ethereum's overall consensus-layer performance or create fragmentation risks in block propagation across different validator groups.
