Optimum's mump2p block propagation layer goes live on Ethereum mainnet
- —16 node operators, including Blockdaemon, Everstake and ether.fi, are running mump2p
- —They control about 22,000 validator keys and 1.4 million ETH, roughly 3.2% of staked ETH
- —Optimum reports blocks arriving 2.42x faster with 7.88x lower arrival variance
- —The sidecar design leaves consensus, execution and signing keys unchanged
Why it matters: Faster block propagation cuts missed attestation rewards and could shift the competitive balance among Ethereum staking operators.
