These blocks are then relayed to validators using MEV-Boost, all while maintaining pre-trade privacy.

The share of Flashbots' MEV Relay continues to drop, with Bloxroute and Blocknative growing their shares of facilitating the production of 18% and 8% of Ethereum's blocks, over the past 7 days.
Also, looks like Agnostic's share is growing the fastest.
