Optimum's MUMP2P networking layer goes live on Ethereum mainnet
Optimum's MUMP2P networking layer is now running in production on the Ethereum mainnet. The layer operates alongside Ethereum's existing GossipSub network and is currently used by about 22,000 validator keys and 16 node operators, representing over 1.4 million ETH in active stake, roughly 3 % of all staked ETH. Ether.fi has made MUMP2P mandatory across all 12 of its node operators. The performance figures are based on Optimum's own measurements, and the infrastructure is live at meaningful scale.
