WTF Is MEV and Why Should We Care?
summary
MEV is the blockbuilder’s ability to capture value by ordering transactions, from NFT mint capture to trading sandwich attacks that force worst prices for users; validators leak TPU flow to searchers and about half a billion of MEV has been extracted on Solana so far. Practical mitigations discussed include stake pools that monitor validators, better DEX designs (order books/auctions), async execution, multiple concurrent proposers and dramatically lower slot times to raise censorship resistance and reduce extractable value.
