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 instances.
Powered by Random Linear Community Coding (RLNC), the system — known as mumP2P — is already displaying main good points on Ethereum’s Hoodi testnet. Early checks by validator big Everstake verify a 5–6x speedup over right this moment’s customary Gossipsub relay.
Working mumP2P, “proper now a median 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 quicker, in the event you can signal block quicker…you may mitigate the danger 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 might be small [1 bip], for instance,” he stated, however on massive quantities of ether staked, it however is usually 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 passionate about enhancing Ethereum’s present networking stack. “[Gossipsub] has loads of redundancy [but] it’s very, very bandwidth hungry, and it actually slows down beneath stress,” Médard advised Blockworks.
Optimum’s resolution goals to interchange it with a better relay that appears like Gossipsub on the surface, however codes knowledge beneath the hood to streamline transmission. Médard defined that in contrast to conventional peer-to-peer relays, which resend the identical knowledge repeatedly, mumP2P makes use of coded packets — mathematical equations which might be virtually at all times new — permitting nodes to transmit info extra effectively and with much less duplication.
Importantly, Everstake’s Opryshko stated his crew hasn’t encountered any significant overhead prices from working mumP2P. “It’s not vital in contrast with the traditional setup.”
Everstake is rolling out in levels on testnet, then transferring on to mainnet. Opryshko recommended that when one consumer crew proves mumP2P delivers higher outcomes, others will possible observe to remain aggressive: “If one exhibits it really works effectively, others will need the identical.”
This isn’t simply an incremental achieve for validators. Ethereum leaders have their sights on shorter slot instances. In Could, EF co-executive director Tomasz Ok. Stańczak posted concerning the community’s technical roadmap: “The place are the shorter slot instances? 6 seconds to start out with and the way we plan for 1s?”
An ETH Analysis report earlier this month suggests median/Ninety fifth-percentile block relay could already match a 6-second slot price range; the issue is outlier validators and attestation timing. With Optimum, Ethereum good points the headroom to shrink slot instances 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 street, Gossip will get caught in a visitors jam, whereas coded propagation doesn’t, so its delay stays low quite than skyrocket beneath stress.
