Optimum’s new propagation layer guarantees to reshape Ethereum’s validator economics, beginning with higher efficiency and better staking yield, however pointing towards future protocol upgrades like shorter slot occasions.
Powered by Random Linear Community Coding (RLNC), the system — known as mumP2P — is already displaying main good points on Ethereum’s Hoodi testnet. Early exams by validator large Everstake verify a 5–6x speedup over immediately’s commonplace Gossipsub relay.
Working mumP2P, “proper now a mean block propagation time is like 150 milliseconds,” Everstake CEO Bohdan “Bo” Opryshko advised Blockworks. For big validator units, Opryshko emphasised, these pace good points aren’t beauty:
“If any person can switch knowledge sooner, should you can signal block sooner…you may mitigate the chance round lacking blocks. Which means much less lacking block, extra rewards for customers, and extra rewards for [validators],” Opryshko stated.
Boosted yields compound at scale. “It may very well be small [1 bip], for instance,” he stated, however on massive quantities of ether staked, it however could be a substantial nominal sum.
Ethereum’s staking yields have seen regular compression since The Merge, Blockworks Analysis knowledge exhibits.

Optimum co-founder Muriel Médard, the MIT professor behind RLNC, is keen about enhancing Ethereum’s present networking stack. “[Gossipsub] has a variety of redundancy [but] it’s very, very bandwidth hungry, and it actually slows down below stress,” Médard advised Blockworks.
Optimum’s answer goals to interchange it with a wiser relay that appears like Gossipsub on the skin, however codes knowledge below the hood to streamline transmission. Médard defined that not like conventional peer-to-peer relays, which resend the identical knowledge repeatedly, mumP2P makes use of coded packets — mathematical equations which are nearly all the time new — permitting nodes to transmit info extra effectively and with much less duplication.
Importantly, Everstake’s Opryshko stated his staff hasn’t encountered any significant overhead prices from working mumP2P. “It’s not important in contrast with the conventional setup.”
Everstake is rolling out in phases on testnet, then shifting on to mainnet. Opryshko prompt that when one shopper staff proves mumP2P delivers higher outcomes, others will doubtless observe to remain aggressive: “If one exhibits it really works properly, others will need the identical.”
This isn’t simply an incremental acquire for validators. Ethereum leaders have their sights on shorter slot occasions. In Might, EF co-executive director Tomasz Okay. Stańczak posted concerning the community’s technical roadmap: “The place are the shorter slot occasions? 6 seconds to begin with and the way we plan for 1s?”
An ETH Analysis report earlier this month suggests median/Ninety fifth-percentile block relay might already match a 6-second slot finances; the issue is outlier validators and attestation timing. With Optimum, Ethereum good points the headroom to shrink slot occasions with out ravenous Ethereum’s fork selection guidelines of well timed knowledge.
Médard places the purpose in roadway visitors phrases: When there are many automobiles on the highway, Gossip will get caught in a visitors jam, whereas coded propagation doesn’t, so its delay stays low fairly than skyrocket below stress.
