# Optimum Launches RLNC-Powered Propagation Protocol for Ethereum Validators

The mump2p network deploys Random Linear Network Coding across global Flexnodes, claiming two to four times faster block delivery than Gossipsub.

## At a glance

- **What happened:** Optimum launched mump2p, a data propagation protocol powered by Random Linear Network Coding designed to speed up block transmission for Ethereum validators.
- **Why it matters:** The overlay claims to deliver blocks up to four times faster than standard Gossipsub, potentially reducing missed attestations and improving proposer MEV margins.
- **Who is affected:** Ethereum validators, node runners, and MEV searchers using low-latency propagation setups.
- **What's next:** The rollout of the announced 'Optimum for Traders' high-speed data acceleration product.

## Key points

- Optimum launched mump2p on its Flexnode mesh to accelerate Ethereum data using Random Linear Network Coding (RLNC).
- The team claims 2x to 4x faster block delivery over Gossipsub and first-seen advantages exceeding 90%.
- The validator integration operates as a drop-in transport layer with no modifications required for consensus rules.

## Editorial remark

- **Context:** P2P network propagation has long been a primary source of latency and attestation failure for Ethereum validators using default Gossipsub routing.
- **Impact:** Ethereum validators deploying the drop-in mesh may lower missed attestations and safely hold MEV bid windows open longer before submitting blocks.
- **Watch:** Release dates and technical specifications for the upcoming 'Optimum for Traders' execution acceleration product.

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](https://basisdesk.news/analysis/ethereum-glamsterdam-upgrade-activates-sepolia-testnet) 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].
