[bitcoin-dev] Question- must every mining rig attempt every block?

[Nathan T Alexander]

For purposes of conserving energy, couldn't each mining rig have some 
non-gameable attribute which would be used to calculate if a block would 
be accepted by that rig?

Don't the mining rigs have to be able to identify themselves to the 
network somehow, in order to claim their block reward? Could their 
bitcoin network ID be used as a non-gameable attribute?

Essentially a green light / red light system. In order for a block to be 
accepted by the network, it must have all attributes of a successful 
block today, and it must also have come from a rig that had a green light.

Perhaps hash some data from the last successful block, along with the 
miners non-gameable attribute, and if it's below a certain number set by 
algorithm, the miner gets a green light to race to produce a valid block.
