block builders on ethereum

tl; dr

• 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
• 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
