Why You Should Be Optimistic About MEV
summary
Block building evolves from opaque mempools to a verifiable market: trusted execution environments power Builderet, a multi-operator network (Flashbots, Nethermind, be forbu) that already builds ~35% of Ethereum L1 blocks and enforces permissionless refunds (≈$1.5M refunded) and orderflow sharing. MEV-Boost drove ~4x more execution-layer rewards but concentrated 90% of blocks in two teams; Builderet claims to reduce that centralization, enable private verifiable auctions, lower spam, and make programmable, resilient block building practical.
