Solana and Ethereum Suffer Billions in Losses as Validator Inflation Bites

Solana and Ethereum have both recorded significant losses in 2025, according to data from crypto analytics provider Kaiko. Solana (SOL) incurred $4.15 billion in net losses, while Ethereum (ETH) lost $1.62 billion. Despite generating revenue through fees, the losses were largely due to validator inflation costs.

The analysis found that token issuance costs far exceeded fee revenue across most major Layer 1 blockchains. This highlights the economic burden of token inflation on holders, as newly issued tokens increase supply and dilute ownership. Tron (TRX) was an exception, recording positive earnings with $624 million in revenue exceeding its token issuance costs.

The report suggests that institutional investors are increasingly evaluating Layer 1 tokens using financial metrics similar to equity markets, including revenue and earnings. Kaiko noted that the long-term sustainability of Layer 1 token economics may depend on networks transitioning toward validator rewards funded primarily through revenue rather than inflation.
