How Does the “Bribe” Mechanism Work in MEV Extraction?
The bribe is the financial incentive paid by a searcher to the block builder/validator to ensure their transaction bundle is included in a block and, crucially, ordered in a specific way. This bribe is typically a portion of the MEV profit and is paid via the transaction's priority fee or an off-chain payment.
The block builder chooses the bundle that offers the highest bribe, maximizing their own profit.
