Ethereum Proposer Weight Model Shows Potential Wait Times
Delphi Digital's study using ETHGas models that at 5% eligible proposer weight, an Ethereum block could take up to four minutes to be produced. At 40% weight, the expected wait drops to about 30 seconds. ETHGas's opt-in institutional service, which reserves blockspace through approved operators, faces a four-minute average wait if those operators hold 5% of the network's proposer-selection weight.
