Explore the complete Cardano ADA supply distribution for epoch 578, which began on 2025-08-22 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.

Epoch 578 facts:
Q: How did the values change compared to the previous Epoch?
A: At the start of epoch 578, the Cardano Ouroboros protocol distributed the staking rewards for epoch 576 and transaction fees collected in epoch 577. This transferred 11,599,949 ada from the reserves to the active supply, equivalent to a 0.17% decrease in reserves and a 0.03% increase in active supply.
Q: How much ada was added to the treasury?
A: In epoch 578, rewards and fees contributed 4,184,938 ada — 36.08% of the overall staking rewards — to the treasury. However, withdrawals of 5,963,280 ada from this epoch outweighed this amount, resulting in a net decrease of 1,778,342 ada (-0.11%) compared to the previous epoch.
Q: How many fees were collected and distributed?
A: In epoch 578, a total of 55,329 ada in transaction fees was collected for a distribution next epoch. 75,916 ada from epoch 577 was distributed as rewards and treasury extension. These fees came from 245,317 transactions, averaging 0.31 ada per transaction, and accounted for 0.65% of the total rewards distributed

Q: Where can I learn more about the Cardano Mainnet reward calculation?
The reward calculation is based on the ledger specification. Further information can be found in the Cardano Blueprint documentation. There is an independent Java implementation with many explanations, as well as a training course from Cardano Academy on calculating staking rewards.
