Validator Inflation Costs Fuel Billion-Dollar Losses for Solana and Ethereum

According to an analysis by Kaiko, Solana and Ethereum have suffered significant losses in 2025. The data provider found that Solana recorded $4.15 billion in net losses, while Ethereum lost $1.62 billion.

The report highlights the issue of validator inflation costs, which far exceed fee revenue across most major Layer 1 blockchains. In other words, the issuance of new tokens to validators and stakers acts as a major economic cost that can outweigh network revenue, effectively diluting token holders.

Tron is an exception, having produced $624 million in revenue that exceeded its token issuance costs, resulting in positive earnings for the year.
