Brief Description: The Bitcoin supply actively participating in the economy expressed as circulating supply adjusted for liveliness.

It is based on the Cointime Economic framework.

Advanced Explanation The Cointime Economics paper by James Check and David Puell (Aug 23, 2023) states 'Active Supply describes an equivalent sum of Bitcoin which has experienced a complete expenditure of all its accumulated cointime. Active Supply can be considered to be the economically meaningful coin volume which is actively participating in the Bitcoin economy.

The Active Supply is computed by:

Supply_Active = Supply Circulating * Liveliness

or

Supply_Active = Supply Circulating * (∑CBD / ∑CBC), 
   where CBD is CoinBlocks Destroyed and CBC is CoinBlocks Created
