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 — referred to as mumP2P — is already exhibiting main beneficial properties on Ethereum’s Hoodi testnet. Early checks by validator big Everstake affirm a 5–6x speedup over at present’s normal Gossipsub relay.
Operating mumP2P, “proper now a median block propagation time is like 150 milliseconds,” Everstake CEO Bohdan “Bo” Opryshko instructed Blockworks. For big validator units, Opryshko emphasised, these pace beneficial properties aren’t beauty:
“If any person can switch knowledge sooner, in case 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 mentioned.
Boosted yields compound at scale. “It could possibly be small [1 bip], for instance,” he mentioned, however on massive quantities of ether staked, it nonetheless is usually a substantial nominal sum.
Ethereum’s staking yields have seen regular compression since The Merge, Blockworks Analysis knowledge reveals.

Optimum co-founder Muriel Médard, the MIT professor behind RLNC, is obsessed with enhancing Ethereum’s present networking stack. “[Gossipsub] has plenty of redundancy [but] it’s very, very bandwidth hungry, and it actually slows down underneath stress,” Médard instructed Blockworks.
Optimum’s answer goals to exchange it with a better relay that appears like Gossipsub on the skin, however codes knowledge underneath 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 can be nearly all the time new — permitting nodes to transmit info extra effectively and with much less duplication.
Importantly, Everstake’s Opryshko mentioned his staff hasn’t encountered any significant overhead prices from operating 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 instructed that after one shopper staff proves mumP2P delivers higher outcomes, others will seemingly observe to remain aggressive: “If one reveals it really works nicely, others will need the identical.”
This isn’t simply an incremental achieve for validators. Ethereum leaders have their sights on shorter slot occasions. In Might, EF co-executive director Tomasz Okay. Stańczak posted in regards to 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 funds; the issue is outlier validators and attestation timing. With Optimum, Ethereum beneficial properties the headroom to shrink slot occasions with out ravenous Ethereum’s fork alternative guidelines of well timed knowledge.
Médard places the purpose in roadway site visitors phrases: When there are many vehicles on the highway, Gossip will get caught in a site visitors jam, whereas coded propagation doesn’t, so its delay stays low fairly than skyrocket underneath stress.
