Blockchain developers are exploring the feasibility of reducing proving times within the current slot structure. The fixed cost component of proving is approximately one second, with potential for further optimization. Currently, half to two-thirds of a slot, or about 1.33 seconds, is available for proving if slots are reduced to two seconds. While engineering this reduction seems feasible, developers emphasize the need for a safety margin, considering factors like backup provers and distributed proving setups. These considerations will influence decisions on whether and when to reduce slot times below four seconds.
