Explore the complete Cardano ADA supply distribution for epoch 571, which began on 2025-07-18 and lasted five days.
This interactive insight helps you understand how the total ADA supply is allocated across key categories — from circulating supply and reserves to staking rewards and the treasury.
At the close of each 5-day epoch, the Ouroboros protocol performs supply and reward calculations across all participating nodes. The resulting transfers distribute staking rewards and allocate a portion to the Cardano treasury, supporting ongoing development and ecosystem growth.
