Solana Marks Two Years Without Mainnet Outage, Fidelity Flags Staking Concentration

Fidelity's framing shifts the Solana conversation from outage history to structural risk: the same performance incentives that secure the network also concentrate stake among a few validators and operators, and custody and client software show similar clustering. That matters for institutions weighing Solana as settlement infrastructure, since resilience now hinges less on uptime than on who controls block production. The slot-time roadmap adds a second variable, as faster blocks raise the bar for validator hardware and could further favor larger operators. Whether concentration metrics improve alongside performance is the open question.
