Why Blockchain Revenue Is Falling
Most chains make money by selling blockspace: users pay gas to get their transactions executed. That product has turned into a commodity. Blockspace from competing L1s, L2s and blockspace-as-a-product providers is interchangeable for most uses, competition keeps pushing fees down, and the most successful apps now earn more than the chains they run on.
In 2021 Ethereum earned $9.91 billion in chain fees, about $826 million a month at the peak, and its chain fees were 1.94 times the fees of every app on it combined. The rollup-centric roadmap then moved activity to L2s, and the Dencun upgrade in 2024 cut L2 transaction costs by 10x with blobs, which also cut what the L1 earns.

Apps keep growing while chain fees shrink. Over the 30 days to June 2026, application fees on Ethereum, Solana, Base, Arbitrum and Avalanche were far larger than the chain fees each network earned.
