Cardano News: Reserve Emissions Remain Key to Staking Rewards

Cardano generated about 3.3 million ADA in transaction fees compared with 493.7 million ADA distributed as staking rewards across the 73 five-day epochs that ended on September 1, 2026. Fees therefore accounted for only about 0.668% of total rewards, leaving the reward pool approximately 149.6 times larger than fee revenue.

The imbalance became more pronounced as network activity declined. Average daily transactions dropped 72.46%, falling from 90,294 in 2022 to 24,869 between January and August 2026. This has made the relationship between transaction fees and staking rewards one of Cardano’s key structural issues ahead of its next major scaling upgrade.

Looking at transactions since Cardano’s genesis block and grouping the data into 73 five-day epochs from September 1, 2025, through September 1, 2026, provides a broader view. The official Epoch 654 snapshot recorded 108,500 transactions and 33,855 ADA in fees over five days, compared with 9.998 million ADA distributed as rewards.

Under Cardano’s monetary system, transaction fees and 0.3% of the remaining ADA reserve are placed into a virtual reward pot during each epoch. The treasury receives 20% of that amount, while the remainder is allocated toward staking rewards based on pool performance.

Cardano’s reserve is designed to decline gradually. Official documentation describes its half-life as roughly four to five years, without setting a specific date for complete depletion. As reserve emissions decrease, the nominal amount available for staking rewards can also decline, potentially reducing the difference between fee revenue and rewards even without an increase in transaction activity.

The network’s current minimum-fee structure combines a fixed charge with a transaction-size component. Governance can modify these parameters, but permanently narrowing the gap ultimately requires greater fee-generating activity rather than relying solely on a declining reward base.

An August public testnet update reported a sixfold improvement in Leios performance under synthetic traffic conditions. However, that result demonstrates increased capacity rather than proof that Cardano’s mainnet will produce enough economic activity to raise fee revenue by anything close to 150 times. Linear Leios is intended to deliver throughput beyond the simplified 43.1 TPS scenario, providing Cardano with a technical route toward handling substantially more activity than it processes today.

The distinction between network capacity and actual demand is not exclusive to Cardano. Solana’s Transaction v1 upgrade tripled data capacity on a network that already generates significantly greater fee volumes, illustrating that additional technical capacity only translates into higher network revenue when applications and users actually utilize it.

Until Cardano attracts enough applications and users to generate paid transactions capable of substantially narrowing the 149.6-fold difference, staking rewards will continue to rely heavily on reserve emissions rather than organically generated network fees. That distinction is important for investors evaluating ADA based on the economics of the protocol rather than its headline staking APY.
