Optimum Launches RLNC-Powered Propagation Protocol for Ethereum Validators

Optimum has deployed the Optimum Network alongside its initial protocol, mump2p, aimed at accelerating transaction, block, and blob propagation across Ethereum ¹. The system uses Random Linear Network Coding (RLNC), an erasure-coding method co-invented at MIT by Optimum co-founder Prof Muriel Médard, to improve fault tolerance and lower latency without altering underlying consensus rules ¹.

At the time of writing, $ETH traded at $2,428, up 1.0% over 24 hours. Optimum's deployment targets execution and consensus layer transport through a distributed mesh of "Flexnodes" ¹. The company claims that the network delivers blocks two to four times faster than Ethereum's standard Gossipsub peer-to-peer layer, with data appearing first on the Optimum mesh in more than 90% of instances compared to Gossipsub ¹. According to the project, the increased speed decreases missed and wrong-head attestations, while allowing block proposers to extend MEV sidecar bid-collection windows without missing proposal deadlines ¹.

Expansion to Trading Infrastructure

The protocol is live for node operators as a drop-in integration through the Optimum console ¹. Because mump2p functions purely as a data-layer transport overlay, node runners do not need to adjust Ethereum consensus parameters or modify existing validator infrastructure ¹. The release arrives as node operators examine low-latency networks in parallel with broader layer-1 developments, such as when Ethereum activates network upgrades to refine consensus scaling.

Following the validator rollout, Optimum stated it plans to introduce an offering designated as "Optimum for Traders" ¹. That planned network aims to provide earlier transaction signaling to trading strategies and accelerate execution onchain, though the team did not publish a specific launch date ¹.
