TL;DR: Fidelity’s technology research team says Solana has operated for more than two years without a major mainnet outage, while maintaining roughly 99.7% vote success. It also warns that validator and infrastructure concentration remain important concerns.
Solana’s reputation was once shaped by how often the network stopped. A new assessment from Fidelity’s Center for Applied Technology shows how much that conversation has changed, without claiming the engineering risks have disappeared.
Published October 16, the research highlights more than two years of operation without a major mainnet outage and a vote success rate of approximately 99.7%. Those measures point to a network that has become more dependable as the financial activity running across it has grown.
The stakes are rising. Fidelity’s researchers note that Solana has handled substantial stablecoin activity and is attracting tokenized assets and institutional participation. A fast chain becomes a very different proposition when users depend on it for more than short-lived speculative trades.
Yet the report does not hand the network an unqualified clean bill of health. Stake concentration, hosting dependencies, software-client diversity and the geographic distribution of infrastructure all influence whether a chain can withstand a serious disruption.
Solana is pursuing further performance improvements, including shorter slot times and new software clients. Those efforts may raise capacity, but raw speed is only one part of network resilience. It also matters how many independent participants can keep a system functioning if a major operator or piece of infrastructure fails.
Fidelity’s central message is less about celebrating a benchmark than about asking a tougher question: can Solana preserve decentralization and reliability as more consequential financial activity arrives?
