Fidelity report finds Solana resilient after two years without mainnet outages but flags concentration risks
Fidelity's research arm says Solana has operated without major mainnet outages for over two years with a 99.7% vote success rate, while warning that stake, hosting, and client software concentration warrant continued monitoring.
Why it matters
The report from a major traditional asset manager signals growing institutional confidence in Solana's operational maturity, which could influence investor sentiment as the network handles increasing financial activity. The identified concentration risks remain relevant for the network's long-term decentralization and resistance to single points of failure.

What happened
Fidelity's Center for Applied Technology published a report assessing Solana's network health, concluding the blockchain has demonstrated resilience across operational measures including more than two years without a major mainnet outage and a vote success rate of approximately 99.7%. The asset manager, which oversees $7.8 trillion, highlighted growing adoption in stablecoin activity, tokenized assets, and institutional participation. However, the report flagged three structural concentration risks that deserve continued monitoring: validator stake concentrated among a small number of identities and operators, hosting dependencies on shared cloud providers and data centers, and client software diversity. Cointelegraph reported Solana recently reduced slot time to 350 milliseconds, the first such reduction since inception, with plans for further reductions to 200ms. Crypto News noted Alpenglow technology targeting 150ms finality could enhance Solana's appeal further.
