Staking rewards generally derive from a combination of inflationary rewards, transaction fees, and MEV. We are certain that a complete understanding of the Ethereum PBS pipeline allows validators to extract more MEV through targeted infrastructure optimizations.
While adjacent topics have been discussed in literature (e.g. Schwarz-Schilling et al., 2023) , Chorus One is the first node operator to successfully test out different optimization approaches on mainnet. We find that the most impactful improvements are contingent on comprehensive internal data, and have generally not been discussed in their specificity.
The goal of this article is to share the results of a recent pilot. We will follow-up with more detail in a later, comprehensive study, which we are co-authoring with one of the most recognizable and competent teams in the MEV space.The pilot makes use of several modifications which positively impact MEV extraction. The rest of the article will discuss one straightforward, illustrative example in more detail, and present the overall results of the pilot so far.
There are two components to APR optimization. Firstly, we should maximize the payoff of the blocks we propose, and secondly, we should minimize the likelihood of missing our chance to propose (i.e. missing our slot). The first of these is more complex and can be approached in several ways, including via latency games, and other infrastructure optimizations.The latter is more accessible, and primarily hinges on running a robust infrastructure setup with appropriate redundancy. However, relay selection also plays a role. Let’s dive in!
A basic illustrative adjustment: drop underperforming relays
