Why It Matters

The concentration of validation power threatens Solana’s decentralization, potentially weakening network security and eroding investor confidence.

Key Takeaways

  • •Validator count fell 68% to 795 nodes.
  • •Nakamoto Coefficient dropped 35% to 20.
  • •Small validators cite unviable economics, high fees.
  • •Large validators charge 0% fees, squeezing competition.
  • •Operating costs need $49k SOL and 401 SOL yearly.

Pulse Analysis

The rapid contraction of Solana’s validator set reflects a broader economic squeeze on blockchain infrastructure. While the network’s high throughput once attracted a diverse validator ecosystem, escalating token‑price‑linked costs and daily voting fees now demand substantial capital outlays. Smaller operators, who historically provided geographic and ideological diversity, are exiting because the revenue generated by transaction fees cannot offset the $49,000‑plus annual SOL stake and the 1.1 SOL per‑day voting expense. This dynamic mirrors challenges seen on other proof‑of‑stake chains where cost structures inadvertently favor well‑capitalized entities.

A declining Nakamoto Coefficient underscores the security implications of this consolidation. With the coefficient now at 20, only a relatively small group of validators can theoretically collude to disrupt consensus, reducing the network’s resilience to attacks. Large validators offering zero‑percent fees further tilt the playing field, as they can undercut smaller peers while still earning rewards from staking. The resulting centralization raises questions about Solana’s claim to a decentralized ledger and may prompt developers and users to reassess reliance on its ecosystem, especially for high‑value or regulated applications.

Looking ahead, Solana’s community and foundation may need to recalibrate incentives to preserve decentralization. Potential measures include subsidizing voting fees for small validators, introducing tiered fee structures, or offering token‑based rebates tied to long‑term participation. Transparent governance reforms that limit the dominance of mega‑validators could also restore confidence. Investors should monitor validator distribution metrics and any policy shifts, as these factors will likely influence Solana’s market positioning and its ability to compete with more decentralized rivals.

Solana validator count drops 68% as node costs squeeze small operators

Solana’s validator count has fallen dramatically over the past three years, raising concerns about the blockchain network’s decentralization as the economics of running a node squeezes out smaller operators.

The number of Solana validators fell 68 % to 795 as of Wednesday, from a peak of 2,560 validator nodes in March 2023, according to Solanacompass data.

Validators are responsible for adding new blocks and verifying transactions in proposed blocks, playing a vital role in the operations of the decentralized ledger.

While some of the decline reflects the removal of inactive or “zombie” nodes, industry participants say increasing operating costs and fee competition are forcing smaller validators offline.

An independent Solana validator operator who posts under the name Moo said on X that many small validators are considering shutting down because the economics no longer make sense.

“Many small validators are actively considering shutting down (including us). Not due to lack of belief in Solana, but because the economics no longer work.”

Moo said large validators charging 0 % fees are forcing smaller validators out of profit, making it economically unviable to continue running a node.

“We started validating to support decentralization. But without economic viability, decentralization becomes charity,” Moo said.

The trend signals that retail validators can no longer sustainably contribute to securing the network. It also shows that Solana’s nodes will be increasingly run by large operators, pushing out smaller players and raising potential concerns related to the network’s degree of decentralization.


Solana’s Nakamoto Coefficient sees 35 % decline

Along with the declining validator count, Solana’s Nakamoto Coefficient also fell by 35 % during the same period, to 20 as of Wednesday from 31 in March 2023, according to Solanacompass.

The Nakamoto Coefficient measures the decentralization of a blockchain by determining the minimum number of independent entities, such as validators or miners. The decline signals that the staked Solana supply is becoming less distributed and the network less decentralized.

The Nakamoto Coefficient for Solana begins at 15 in May 2021, increases over time to 35 in September 2023, then decreases to 20 by November 2023. It remains at 20 for the rest of the period of time covered by the graph, which ends in January 2026

A reason behind this decline may be the increasing costs of running a profitable validator node, which rose significantly over the past three years along with the Solana token.

Excluding hardware and server costs, validators need an initial investment of at least $49,000 in SOL tokens for the first year of operations, requiring at least 401 SOL each year for voting fees to remain operational.

This is because validators need to participate in protocol consensus, requiring them to send a vote transaction for each block the validator agrees on, which can cost up to 1.1 SOL per day, according to Solana validator Agave’s technical documentation.

Cointelegraph contacted the Solana Foundation for comment, but had not received a response by publication.
