Active supply

the bitcoin that is economically awake

The equivalent number of bitcoin that are economically active, rather than sitting still. It is not a list of particular coins, it is a volume, which is exactly how it sidesteps having to decide which coins are lost.

DefinitionCirculating supply x liveliness. Active supply plus vaulted supply equals circulating supply exactly.

LimitIt is an equivalent volume, not a set of coins. No individual coin is "in" it. Cointime measures are cumulative since genesis, so they move very slowly and stay anchored to early history. They describe a regime, not a trade. Being corrected: this is built on active or vaulted supply, which the pipeline derived from the coinblocks liveliness while the published liveliness is coin-days. The gap averages 74,759 BTC of active supply, a median of 0.8%. The rebuild onto coin-days is under way and this caveat retires with it.
