+ +* block builders have the same 3 sources of tx as validators did before the merge. they can: + 1. act as searchers and include their own MEV-extracting transactions. + 2. include txs submitted to them privately, including those submitted by external searchers (through a "bribe" through either coinbase payments or `txsFees`). + 3. include pending tx broadcasted in the public mempool +* `blockValue` = `txFees` + MEV * builders will aggregate txs from users, MEV searchers, and own private order flow to make the highest value blocks possible - * `blockValue` = `txFees` + MEV - * block bidding is carried out as a sealed bid auction - * however, searchers can pay the builder through either coinbase payments and `txsFees` -* builders with exclusive private orderflow should create the most valuable block. * builders having its blocks included consistently incentivizes more private order flow (searchers want their tx included) * builder can be selling future blockspace upfront so market makers or protocols can secure block space for their transactions or users +
