Finally, the ultimate evolution is the . Imagine a validator client (like Lighthouse or Prysm) that includes a native "Flash Minibuilder" module. The validator wouldn't need MEV-Boost at all; they would simply run their own local minibuilder, capture the MEV directly, and avoid paying relay fees entirely. This would be the death of the external builder market as we know it. Conclusion: Size Doesn't Matter, Latency Does The era of the monolithic, omnivorous block builder is slowly sunsetting. In its place rises the Flash Minibuilder: agile, hungry, and blindingly fast.
To the validator, the bid is what matters. If the Flash Minibuilder can pass through a $5,000 bid with 50ms latency, and the monolithic builder offers a $5,100 bid with 500ms latency, the validator faces a risk/reward calculation. flash minibuilder
A monolithic builder sends a heavy block with 150 transactions (including low-value backruns and sandwich attempts). A Flash Minibuilder sends a lean block with 3 high-value transactions. Finally, the ultimate evolution is the

The latency here is brutal. By the time a builder compiles a block, a searcher’s arbitrage opportunity might have vanished, or a better bid might have appeared on the network. Furthermore, monolithic builders often rely on a single software stack (like mev-geth ), creating centralization risks and single points of failure.
