Solana Validator Count Drops 68% as Rising Costs Force Small Operators Out

TLDR

• Solana’s validator count has fallen by 68%, from 2,560 in March 2023 to 795 as of Wednesday.
• The drop in validator numbers is driven by rising operating costs and increasing fee competition.
• Small validators are struggling to remain profitable, with many considering shutting down their nodes.
• Large validators offering 0% fees are pushing smaller operators out of the market.
• Solana’s Nakamoto Coefficient has dropped by 35%, indicating a decline in decentralization.

The number of Solana validators has decreased by 68%, raising concerns about decentralization on the blockchain network. As of Wednesday, the validator count stood at 795, a sharp drop from a peak of 2,560 in March 2023. Industry participants indicate that the rise in operating costs and fee competition are forcing smaller validators offline.

Rising Costs Push Small Validators Out

The drop in the number of Solana validators reflects the increasing difficulty for smaller operators to sustain their operations. High operating costs, especially for hardware and server maintenance, are becoming burdensome for retail validators. In addition, the need for at least 401 SOL tokens annually to cover voting fees has led many smaller validators to question the economics of running a node.

Moo, an independent Solana validator operator, shared concerns on social media about the profitability of small validators. “Many small validators are actively considering shutting down,” Moo said. They explained that the decision is not due to a lack of belief in Solana but the unviable economics. With large validators charging 0% fees, small operators are struggling to remain profitable.

This change highlights a shift toward fewer, larger operators managing the network’s validation. As smaller players are driven out, concerns about decentralization are growing. The network’s decentralization may become less sustainable as the concentration of power moves toward these larger validators.

Solana Validator Count Declines Amid Fee Competition

The decline in Solana’s validator count correlates with rising fee competition. Large operators who offer minimal to no fees are making it harder for smaller validators to stay afloat. These larger entities can leverage economies of scale that smaller players simply cannot match, pushing out the smaller operators.

The Solana Nakamoto Coefficient, a key measure of decentralization, has also taken a hit. It dropped 35%, from 31 in March 2023 to 20 this week. This decrease signifies that fewer independent entities are securing the network, contributing to concerns about its overall decentralization.

Operating a Solana node has become more expensive, with some validators needing an investment of $49,000 for the first year alone. This includes not only hardware and server costs but also the required SOL tokens for voting.
