Solana is known for its commitment to high-speed blockchain technology. But behind its claims of superiority lie serious problems that undermine its reliability and decentralization. Essentially, there are three main problems with the current Solana ecosystem: frequent network outages, misleading TPS metrics, and validator centralization.
frequent interruptions
Since launching in 2020, Solana has experienced 12 major network outages, bringing down dApps, traders, and the platform. These outages are often caused by network congestion, validator errors, or bugs, with some lasting as long as 17 hours. A notable case that occurred in September 2021 caused confusion for users who were unable to access their funds or complete transactions during the downtime.
Additionally, in January 2022, a DoS attack overwhelmed the network, further highlighting the vulnerability of the network. For a blockchain with a total value locked (TVL) of over $10 billion at the time, these outages resulted in significant financial losses and decreased trust in the reliability of the network.
TPS Myth
Solana’s marketing boasts up to 65,000 TPS, a figure that far surpasses competitors such as Ethereum. However, these numbers can be misleading. In fact, Solana artificially inflates the number by including validator votes and failed transactions in TPS calculations. Actual TPS for user transactions is closer to 250 TPS, which is much lower than the sold figure.
For comparison, Ethereum processes 30 TPS for a successful transaction, but the TPS reported by Solana includes activities that do not directly benefit users. These misleading metrics paint a misleading picture of Solana’s performance, making it appear to be performing much better than it actually is.
Validator centralization
Unlike other blockchains that aim to be decentralized, Solana’s validator network is highly centralized. The top 18 validators control over 33% of the staked supply, giving a small group significant influence on the network. This level of control allows validators to potentially censor transactions or block consensus.
Becoming a validator on Solana is expensive, with the average cost for hardware and operations exceeding $500,000 per year. Additionally, validators must have at least $20 million in SOL to have meaningful influence. This creates high barriers to entry, limiting participation to only the wealthiest individuals or institutions.
Additionally, Jupiter, Solana’s leading DEX, operates one of the top 18 validators. This creates a potential conflict of interest because Jupiter can profit from creating and validating failed transactions and also receive fees when users fail. This centralized and validator-driven revenue model raises serious concerns about the integrity of the network.
Solana’s promise of fast speeds and low costs has been eclipsed by frequent outages, inflated TPS metrics, and validator centralization. With 12 major outages, Jupiter’s high transaction failure rate of 75.72%, and a validator structure that favors the wealthy, Solana faces significant challenges. While the network may seem attractive on the surface, these fundamental issues make it clear that Solana’s future is far from certain.
