So this dropped on Github yesterday and you may be wondering what it is.

*Pomp brother voice*
Here's a thread ⛏️

Miner Extractable Value (MEV) describes any value miners (or traders) squeeze out of sequencing transactions.

Typically its done on the in-coming block. A miner, say @ethermine_org can choose how to sequence the block if they find the nonce.

But what if you could go back in time? 🤔

You can with blockchains, if you have the right tools. Here, the tip of the chain is re-orged to sequence transactions favorably to miners in what is called a time bandit attack.

Time bandit's subsidize short term reorgs through the additional MEV found. You find additional MEV because you know what future transactions look like.

To date, its been an area miners and others have not been willing to go because it would hurt Ethereum's consensus and therefore its asset.

But with PoS coming to Ethereum, what do miners have to lose?
