Evaluating Solana Network Resilience and Uptime

A recent report from Fidelity’s Center for Applied Technology (FCAT) has shed light on the state of the Solana blockchain, emphasizing its operational stability alongside notable infrastructure vulnerabilities. According to the report, Solana network resilience has improved significantly, marked by a period of more than two years without a major mainnet outage.

Authored by Mia Galvin and Kevin Kelly and published on October 16, 2026, the document titled “The State of Solana: Network Health and Resilience” highlights that the network has not experienced a major disruption since February 6, 2024. Furthermore, the report notes that Solana achieved a vote success rate of approximately 99.7% in 2026 as validators work to confirm blocks.

The network has also expanded its capacity by shortening its slot times, which are the brief windows during which validators produce blocks. Shorter slots enable the chain to handle higher transaction volumes to accommodate growing user demand.

Growth in Tokenized Assets and Stablecoin Volume

Alongside uptime improvements, the report points to substantial growth in financial activity on the blockchain. Tokenized real-world assets on Solana surged from approximately $1 billion to $4.4 billion year over year, according to FCAT data.

Stablecoin activity experienced even faster adoption. The research notes that Solana processed over $2 trillion in stablecoin volume during the first quarter of 2026 alone, underlining increased utilization of the network for digital currency transactions.

Concentration Risks in Stake, Hosting, and Clients

Despite positive metrics regarding uptime and usage, FCAT cautions that the network faces systemic vulnerabilities due to structural concentration. The report reveals that about 18 validators together control enough stake to potentially halt finality, which is the point where a transaction is settled and cannot be reversed.

Hosting concentration presents another major concern. A single hosting provider controls nearly 29% of the total network stake, a figure that exceeds acceptable limits established by the Solana Foundation. Geographically, approximately 40% of the stake is concentrated in Frankfurt and Amsterdam.

Client software distribution also shows heavy reliance on specific codebases. The report states that about 63% of the stake runs Jito-Solana, while 26% runs Harmonic. FCAT notes that both clients are linked to the dominant Agave codebase, meaning a single flaw in the underlying code could simultaneously impact the majority of the network.
