Solana validator nodes plummet 68% in three years, decentralization under scrutiny, small operators collectively under pressure

January 29 News, the Solana network is facing a structural change. Data shows that the number of validator nodes has decreased from a peak of 2,560 in March 2023 to the current 795, a decline of 68%. The sharp reduction in nodes has sparked ongoing concerns about Solana’s decentralization and network security.

Validator nodes are at the core of blockchain operation, responsible for packaging new blocks, validating transactions, and participating in consensus. Although part of the decline is due to cleaning up inactive nodes, industry experts generally believe that the real pressure comes from rising operational costs and fierce fee competition. Moo, an independent node operator, stated on social media that many small nodes are not退出 due to losing confidence in the ecosystem, but because long-term losses have made it difficult to sustain.

Moo pointed out that large nodes compete for staking resources with nearly 0% fees, while small operators have almost no profit margin. “Without economic returns, decentralization is only an ideal,” he described the current dilemma. This trend indicates that network validation power is gradually concentrating in a few large entities.

Decentralization indicators also send warning signals. According to Solanacompass, Solana’s Satoshi coefficient has dropped from 31 in March 2023 to 20 this week, a decline of about 35% over three years. This metric measures the minimum number of independent entities needed to control the network; a decrease in value signifies increased concentration of power.

High costs are considered a core reason. Besides hardware and server expenses, validators need to stake approximately $49,000 worth of SOL in their first year, and pay about 401 SOL annually for voting fees. According to Agave documentation, daily voting can consume up to 1.1 SOL, which significantly raises operational thresholds after price increases.

Changes in the node ecosystem are reshaping Solana’s network structure. If small operators continue to退出, validation power may become even more concentrated in the future, posing new challenges to the blockchain’s emphasis on openness and resistance to censorship.
