Solana (SOL) recorded $4.15 billion in net losses in 2025 while Ethereum (ETH) lost $1.62 billion, according to analysis from crypto data provider Kaiko, which found that validator inflation costs far exceeded fee revenue across most major Layer 1 blockchains. Despite Ethereum generating $260 million in revenue and Solana producing $170 million in fees, only Tron (TRX) recorded positive earnings after bringing in $624 million in revenue that exceeded its token issuance costs.
The findings highlight how token inflation, new tokens issued to validators and stakers, acts as a major economic cost that can outweigh network revenue, effectively diluting token holders.
Validator Inflation Outpaces Blockchain Revenue
Kaiko’s analysis evaluates blockchain earnings by comparing annual fee revenue against the market value of newly issued tokens distributed to validators or stakers.
While transaction fees represent the income generated from network activity, the issuance of new tokens functions as a cost to holders because it increases supply and dilutes existing ownership.
Using that framework, the report found that inflation costs across many Layer 1 networks exceed revenue by multiples ranging from seven to 25 times.
Solana’s network generated approximately $170 million in fees in 2025 but recorded $4.15 billion in losses after accounting for validator issuance.

Ethereum collected around $260 million in annual revenue yet still posted $1.62 billion in net losses under the same calculation.
By contrast, Tron produced $624 million in revenue during the year and maintained net token deflation, meaning fee income exceeded newly issued tokens.
Institutional Investors Increasingly Focus On Protocol Earnings
The profitability question has become more prominent as institutional access to crypto expands through exchange-traded funds and greater regulatory clarity.
Kaiko noted that Layer 1 tokens are increasingly evaluated using financial metrics similar to equity markets, including revenue and earnings.
Ethereum’s economic model has also shifted significantly following the Dencun upgrade, which redirected much of the network’s transaction demand to Layer 2 scaling systems.
According to the analysis, Ethereum’s daily revenue fell sharply after the upgrade as fees moved toward blob-based pricing for rollups.
The report suggests that the long-term sustainability of Layer 1 token economics may depend on whether networks can transition toward validator rewards funded primarily through revenue rather than inflation.
Among major chains today, Tron remains the only traditional Layer 1 operating with positive earnings under that framework, highlighting a growing divide in blockchain economic models.
