By Unchained
AI summary of the source article
Liquid restaking provider ether.fi is mandating Optimum’s mump2p block-propagation software across all 12 of its node operators. The software is now live in production on Ethereum mainnet to accelerate block delivery.
Why it matters
Rok Kopp, ether.fi’s co-founder and chief growth officer, stated: “We don’t mandate new infrastructure across our entire validator set unless we’re confident it raises the bar for our stakers and for the network.”
Key facts
- Ether.fi requires all 12 of its node operators, running roughly 22,000 validator keys with over 1.4 million staked ETH, to use Optimum's mump2p.
- Optimum claims its software delivered blocks 2.42 times faster and with 7.88 times lower arrival-time variance than Ethereum's default GossipSub protocol.
- Optimum raised an $11 million seed round led by 1kx and ran a private testnet with seven operators in June 2025.
