Cardano Supply Overview

Visual representation of ada supply distribution across key categories in the Cardano network.

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.

Epoch 571 facts:

Q: How did the values change compared to the previous Epoch?

A: At the start of epoch 571, the Cardano Ouroboros protocol distributed the staking rewards for epoch 569 and transaction fees collected in epoch 570. This transferred 11,698,839 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 571, rewards and fees contributed 4,203,257 ada  — 35.93% of the overall staking rewards — to the treasury. After accounting for withdrawals of 1,500,000 ada from this epoch, the treasury increased by 2,703,257 ada (0.15%) compared to the previous epoch.

Q: How many fees were collected and distributed?

A: In epoch 571, a total of 68,455 ada in transaction fees was collected for a distribution next epoch. 63,716 ada from epoch 570 was distributed as rewards and treasury extension.  These fees came from 197,266 transactions, averaging 0.31 ada per transaction, and accounted for 0.54% of the total rewards distributed

Q: Were there withdrawals from the treasury in epoch 571?

A: There were 5 treasury withdrawals totaling 1,500,000 ada.

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.
