is an improved version of Ampleforth (AMPL) that hard forked
during mid-August of 2020. It improved upon the disadvantage faced by worldwide users of encountering the "basing window time" lying in the odd hours. COIL has a 23-hour retargetting mechanism that ensures everyone around the world gets an equivalent oppurtunity to witness the base and take trading/speculating decisions far more comfortably. It levels the ground and gets rid of the unfair advantage assigned to a particular Time-Zone.
COIL Dollar CPI
The Ampleforth CPI (Consumer Prices Inflation) records began at $1 (USA dollar) on Jun-14-2019 (01:26:28 AM UTC) as the base rate. Since then (a.k.a. "Genesis"), the Oracle (ChainLink) has been feeding the USD CPI onto the Ethereum blockchain.

CPI at Hard Fork
COIL uses the Oracle (same, ChainLink) to input the Inflation (CPI) data into its own Smart Contract to revise its monetary policies every 23 hours. The CPI at the time of the Hard Fork was 110.356333333333339472% (absolute) and is hard-coded into the COIL Smart Contract

+ Target Price
COIL re-targets the USD adjusted to inflation (CPI in USA).
First target was exactly $1 and it gradually increased due to persisting devaluation of the U.S. Dollar by inflation.
The price reported by the COIL's Price Oracle determines the change in total supply of COIL.Such an event is called a Rebase.
If it is higher than the upper threshold, the overall supply of COIL is increased.
If it is smaller than the lower threshold, the overall supply of COIL is reduced.This kind of event is termed a Debase.
However, if the Oracle's reported price is in between the upper & lower thresholds, there is no change in monetary supply.
Such a base is known as Neutral base.
All the addresses, including Springs, Waterfall, Treasurary, Uniswap pool, etc. undergo all the bases, be it the neutral, a rebase or a debase.
