Solana’s Validator Count Declines, Raises Concerns about Decentralization in the Face of Rising Costs and Competition

The number of validators on the Solana blockchain has plummeted by 68% in the last three years, sparking worries about the network’s decentralization as smaller operators struggle to keep up with increasing costs.

As of Wednesday, there were only 795 validators on Solana, a significant drop from the peak of 2,560 in March 2023, according to data from Solanacompass.

Validators play a crucial role in the decentralized ledger by adding new blocks and verifying transactions, but the recent decline can be attributed to a combination of inactive or “zombie” nodes being removed and smaller validators being pushed out by larger competitors.

Moo, an independent Solana validator operator, shared on X that many smaller validators are considering shutting down due to the unsustainable economics of running a node.

“The economics no longer make sense for many small validators, including us. We didn’t enter this space to make a profit, but without economic viability, decentralization becomes a form of charity,” Moo said.

This trend highlights the difficulty for retail validators to contribute to securing the network and suggests that larger operators will dominate, potentially raising concerns about the level of decentralization on Solana.

Solana’s Nakamoto Coefficient experiences 35% decrease

In addition to the declining number of validators, Solana’s Nakamoto Coefficient has also dropped by 35% during the same timeframe, now standing at 20 compared to 31 in March 2023, according to Solanacompass.

The Nakamoto Coefficient is used to measure the decentralization of a blockchain by determining the minimum number of independent entities, such as validators or miners. This decrease indicates that the staked supply of Solana is becoming less distributed and the network is becoming less decentralized.

One possible reason for this decrease could be the rising costs of running a profitable validator node, which have significantly increased over the past three years along with the value of the Solana (SOL) token.

Excluding the costs of hardware and servers, validators must have an initial investment of at least $49,000 in SOL tokens for the first year of operation and must continue to have at least 401 SOL each year for voting fees to remain operational.

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

Cointelegraph reached out to the Solana Foundation for comment but has not yet received a response at the time of publication.
