Running an Ethereum validator shouldn't depend on how close your infrastructure is to major network hubs. But network geography can create an advantage. Some validators operate close to well connected data centres, while others are spread across regions with longer network routes and less favourable connectivity. When a new block is proposed, every validator needs to receive it in time to participate in consensus. A validator that receives the block late has less time to process it and submit its attestation. Repeated delays can affect its performance and rewards. This is an important problem @get_optimum is working to address. Through mump2p, Optimum uses Random Linear Network Coding (RLNC) to improve how Ethereum block data travels between nodes. The goal is to make block delivery faster and more consistent across the network, including for nodes that are harder to reach. This matters because improving the experience of remote validators can help reduce the networking advantage enjoyed by infrastructure concentrated in major hubs. Optimum's mainnet launch data highlighted particularly strong improvements at the edges of the network. I like this aspect of the technology because Ethereum decentralization is not only about allowing more people to run validators. It's also about giving those validators a fairer chance to receive the information they need on time. Better data propagation can help make that possible.
