Fidelity's FCAT Flags Solana (SOL) Stake Concentration After Two Years of Zero Mainnet Outages

Solana (SOL) has now completed two consecutive years without a single reported mainnet outage, and the assessment behind that figure comes from an unlikely corner of traditional finance: Fidelity. The asset manager's Applied Technology Center (FCAT), its in-house research arm, published the evaluation, which also flags stake concentration on the network as an area of concern.

Two Years of Zero Reported Outages

The headline finding is a reliability milestone for Solana: two full years of mainnet operation with no reported outages. That record stands in notable contrast to the network's earlier history, when a series of downtime events during 2021 and 2022 drew criticism and became a recurring point of contention for skeptics of the blockchain.

For a network whose earlier downtime served as a standing talking point for critics, a sustained run of uninterrupted operation reflects the kind of operational stability that institutional research teams weigh when assessing public blockchains. It does not answer every technical question about the network, but it speaks directly to the objection most often raised during that earlier period.

The Flag: Stake Concentration

FCAT's assessment is not an unqualified endorsement. According to the published findings, the research arm highlights the concentration of staked SOL as an issue worth monitoring.

Solana operates as a proof-of-stake network, in which validators secure the chain by staking SOL and token holders can delegate their holdings to those validators. In such systems, the distribution of staked tokens is a core measure of decentralization. When a large share of stake is concentrated among a small number of validators or related entities, it can raise questions about network resilience, governance influence, and censorship resistance.

One practical feature of this concern is that it is continuously observable: delegations to validators are recorded on the blockchain itself, so the distribution of staked SOL can be checked at any time rather than waiting for the next research note. That makes the issue directly measurable by anyone following the network.

Traditional Finance Keeps Watching

Fidelity, one of the world's largest asset managers, has steadily expanded its digital asset operations in recent years, and FCAT publishes research on blockchain networks and crypto infrastructure. That a major traditional finance institution is tracking Solana's uptime record and its validator economics reflects the growing attention established financial firms are paying to the technical fundamentals of public blockchains.

Read together, the report's two findings frame what to watch on the network going forward: whether the uptime streak documented by FCAT continues, and how the distribution of staked SOL shifts across validators over time. Both are measurable signals of the kind research teams such as FCAT already evaluate, and both are likely to anchor future assessments of the network's reliability and decentralization.
