Solana and Ethereum Suffer Billions in Losses Amid Validator Inflation Costs
A recent analysis from crypto data provider Kaiko has shed light on the financial performance of several major Layer 1 blockchains in 2025. According to the report, Solana (SOL) recorded $4.15 billion in net losses last year, while Ethereum (ETH) lost $1.62 billion.
The findings highlight how token inflation can act as a significant economic cost, effectively diluting token holders' ownership. Validator issuance costs far exceeded fee revenue across most major Layer 1 blockchains, with Solana generating approximately $170 million in fees but recording $4.15 billion in losses.
Ethereum collected around $260 million in annual revenue yet still posted $1.62 billion in net losses under the same calculation. In contrast, Tron (TRX) produced $624 million in revenue during the year and maintained net token deflation, meaning fee income exceeded newly issued tokens.
