⚡️ Ethereum's Block Delivery Just Got a Potential 3.5x Speed Boost An independent team, @get_optimum, is bringing an alternative networking solution to Ethereum. Its new P2P protocol, mump2p, went live on Ethereum mainnet on October 20, 2026. Here's why it matters 👇 1/ The problem: Slow block propagation When a validator produces a new block, it must distribute that block to other validators worldwide. The faster they receive it, the sooner they can process it and reach consensus. Ethereum currently uses GossipSub to distribute this data. 2/ The solution: mump2p Optimum uses a technology called Random Linear Network Coding (RLNC). Instead of repeatedly forwarding identical data, mump2p: - Splits information into smaller pieces. - Combines them into coded packets. - Allows validators to reconstruct the original data after receiving enough packets. Think of it like downloading a large file through multiple sources instead of relying on one source. The goal is to make block distribution faster and more efficient. 3/ The reported results According to Optimum: - Up to 3.5x faster block delivery compared with standard GossipSub. - 7.8% of staked ETH represented by participating validators by November. - Works alongside existing consensus clients without changing Ethereum's consensus rules. However, independent testing by StereumLabs found mixed results across different clients. More testing is needed to validate the gains. 4/ Why does this matter? Faster block propagation can help Ethereum achieve: - Lower delays in block distribution. - More efficient communication between validators. - Better infrastructure for future network scaling. Vitalik has also discussed erasure-coded networking as part of Ethereum's future roadmap, although those proposals are separate from Optimum's implementation. Ethereum scaling isn't just about higher TPS or cheaper gas fees. The underlying networking infrastructure matters just as much. What's interesting here is that an independent team like Optimum is experimenting with an alternative solution without requiring changes to Ethereum's consensus rules. It's not a direct TPS upgrade, but if proven effective at scale, it could become an important improvement to Ethereum's infrastructure.
