The Solana validator landscape has changed drastically over the past year. The chain now has 1,332 active validators with 380.9 million SOL staked (63.9% of supply) as of February 2025. Validator revenue had diversified beyond inflationary rewards (still making up 55%) to include Jito tips (30%), priority fees (24%), and base fees (<1%), in January, especially with the increased activity on Solana. Since then, issuance has become dominant again (76%), while Jito tips (14%), priority fees (9%), and base fees (less than 1%) have reduced in share of February 2025. There has been a strong shift towards non-inflationary revenue sources, which have become more central to validator economics as priority fees and off-chain blockspace auctions gain traction. Client diversity has also improved drastically, with implementations such as Agave, Jito-Solana, and Frankendancer already in use, and upcoming clients like Firedancer and Sig expected to further strengthen resilience and reduce reliance on a single codebase.

Even as the most performant, widely used blockchain today, Solana is still far from perfect, prompting some teams to iterate upon some design choices while maintaining compatibility at the SVM execution layer. This report analyzes three emergent SVM chains (Eclipse, Atlas, and Fogo) to understand the motivations behind the technical architectures, as well as the current state and future outlook.
