The liquid staking protocol now requires all 12 of its operators to run the faster block propagation software on Ethereum mainnet Ether.fi has turned a nice-to-have into a must-have. The liquid staking protocol now requires all 12 of its node operators to run mump2p, a networking tool built by startup Optimum. Until now, using the software was optional for Ether.fi operators. The change came alongside Optimum’s mainnet launch of the protocol on October 20, 2026. With that move, 16 Ethereum node operators are now running mump2p in production.
