$SOL's been running clean for 2+ years straight—no major outages. Fidelity's research team confirms network health is improving, but they're flagging stake concentration as a watch point.

This is massive for institutional narrative. Two years of uptime after the 2022 chaos? That's the kind of reliability tradfi needs to see before they deploy serious capital.

Stake centralization is the only real concern here. If too much power sits with a few validators, it opens attack vectors and kills the decentralization thesis. But if they're actively monitoring it, that's a green flag.

Bottom line: $SOL's infrastructure story is getting stronger. If they keep this up while addressing validator distribution, we're looking at a top-tier L1 play for the next cycle.
