Optimum’s new propagation layer promises to rebuild Ethereum’s Validator Economics. This starts with improved performance and improved staking yield, but points to future protocol upgrades such as short slot times.
Systems with random linear network coding (RLNC) (a system called MUMP2P) already show the great benefits of Ethereum’s Hoodi testnet. Early tests by Validator Giant Everstake have confirmed five to six times faster than today’s standard Gossipsub relay.
Running Mump2p, “Currently, the average block propagation time is like 150 ms,” Everstake CEO Bohdan “Bo” Opryshko told BlockWorks. For large validator sets, Opryshko highlighted, these speed improvements are not cosmetics.
“If someone can transfer data faster, if they can sign a block… they can reduce the risk around missing blocks. That means fewer blocks are missing, more rewards for users, and more rewards for (validators),” Opryshko said.
Boosts produce compounds on scale. “For example, it could be small (one bip),” he said, but even if a large amount of ether bets, it could be a fair nominal sum.
Ethereum staking yields have been seen as stable compression as Merge, Blockworks research data show.

Muriel Médard, the MIT professor behind RLNC, is keen to improve Ethereum’s current networking stack. “There’s a lot of redundancy in (Gossipsub) (but) it’s very, very, very bandwidth hungry and really slows down under stress,” Médard told Blockworks.
Optimum’s solution is intended to replace it with a smarter relay that looks like an outer Gossipsub, but codes the data under the hood to streamline the transmission. Médard explained that unlike traditional peer-to-peer relays, which retransmit the same data repeatedly, Mump2p uses coded packets (almost always new mathematical equations) to allow nodes to send information more efficiently and with fewer overlap.
Importantly, Everstake’s Opryshko said that he has not encountered any meaningful overhead costs since his team ran Mump2p. “It’s not important compared to a regular setup.”
EverStake is deployed during the testnet stage and then moved to MainNet. Opryshko suggested that once one client team proves Mump2P will deliver better results, it is likely that the other teams will continue to stay competitive.
This is more than just an incremental gain for the validator. Ethereum leaders aim for shorter slot times. In May, EF co-executive director Thomas K. Studzak posted about the network’s technical roadmap.
An ETH survey report earlier this month suggests that the median/95 periodic block relay could fit the already 6-second slot budget. The problem is the timing of outlier validators and proofs. Ethereum reduces slot time without starving headroom when optimal and hungering Ethereum fork selection rules for timely data.
Medard places a point on road traffic conditions. If there are plenty of cars on the road, gossip gets stuck in traffic jams, but coded propagation is not so, so delays remain low rather than surged under stress.
