Ethereum block propagation is now twice as fast for several validators without altering the network’s underlying consensus. Around 90% of blocks reportedly reach participating validator nodes twice as fast compared to standard transmission via a peer-to-peer protocol named mump2p. The figures were announced by Muriel Médard, co-founder of Optimum and professor at the Massachusetts Institute of Technology (MIT), on November 10, 2026.
The mump2p protocol officially launched on the Ethereum mainnet on October 20, 2026, to address bottlenecks in the conventional GossipSub system. Under the legacy system, validator nodes often receive redundant message copies and experience transmission delays due to bandwidth variations. Optimum’s protocol operates alongside existing consensus clients without modifying the network’s consensus rules.
Why Data Doesn’t Need to Wait for Complete Packets
Transmission is accelerated using Random Linear Network Coding (RLNC) technology to send encoded data across peer-to-peer networks. Data chunks are combined before being broadcast across the network, enabling validators to reconstruct entire blocks as soon as they collect a sufficient number of independent combinations. Validators do not need to wait for complete data packets to arrive sequentially.
The mump2p gateway runs alongside validator consensus software without requiring a hard fork or modifications to Ethereum’s codebase. The software supports the network’s five major clients: Prysm, Lighthouse, Teku, Nimbus, and Lodestar.
Test Results Across Hundreds of Thousands of Slots
Optimum’s internal analysis of 50,292 Ethereum slots recorded an average distribution time advantage of 335 milliseconds, representing a 3.3-fold speed increase compared to the standard system. In addition to faster distribution, the variance in packet arrival times dropped by up to 7.88 times.
Testing through Lido’s evaluation program yielded consistent results. Across a trial of 180,327 testnet slots between September 17 and October 15, blocks arrived 407 milliseconds faster at testing nodes.
Backing from 16 Staking Operators
A total of 16 professional node operators have connected to the mump2p network since its official launch. Together, they manage approximately 22,000 validator keys and over 1.4 million staked ETH, representing $3.4 billion in Total Value Boosted. The operators involved include Blockdaemon, Everstake, P2P.org, Stakefish, Luganodes, InfStones, and Validation Cloud.
Protocol adoption expanded further after restaking provider ether.fi mandated that 12 of its node operators run mump2p. This policy pushed mump2p adoption to cover 7.8% of all staked ETH on the Ethereum network as of November 3, 2026.
For validator operators, cutting block transmission delays serves as a technical option that can be deployed independently on their respective machines. Without having to wait for network consensus rule overhauls, validators are now free to optimize their data arrival times. Reported by crypto.news.
