Definition. Entity-Adjusted 90D Coin Days Destroyed (eCDD-90) is the 90-day rolling sum of Coin Days Destroyed (CDD), with transactions between addresses controlled by the same network participant discarded and the result normalized by time to account for the increasing destructible-coin-age baseline.

Technical. Same-entity reshuffles are filtered at the daily layer using account-based clustering before the 90-day rolling sum is taken. Time normalization adjusts for the secular drift in the destructible coin-age inventory as the network ages.

Notes. For more information on entity-adjustment and account-based metrics, read our articles here and here.

This is the Point-in-Time (PiT) variant of Entity-Adjusted 90D Coin Days Destroyed (eCDD-90). PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
