In 2026, the bigger question is changing.

Solana doesn't simply need to prove that people can use the network. It needs to prove that its activity can remain valuable, reliable and sustainable over the long term.

Speed Is Still Solana’s Biggest Advantage

Solana continues to push performance forward.

In September, the network reduced its target slot time from 300 milliseconds to 250 milliseconds. This means applications can receive updated information faster, although the change itself does not increase overall transaction capacity by the same percentage.

Solana is also testing Alpenglow, a major consensus upgrade designed to reduce finality from roughly 13 seconds to around 150 milliseconds.

If successfully deployed, this could make the network feel even closer to the speed users expect from traditional financial applications.

Users Are Already Showing Up

Speed means little without activity.

Solana recorded billions of non-vote transactions during individual months in 2026, while activity across trading, payments, stablecoins and other applications remained significant.

The network has also demonstrated that it can process heavy demand without experiencing the reliability problems that damaged its reputation in earlier years.

Solana says it has maintained continuous uptime since February 2024.

That's important progress.

But Activity Needs to Become Sustainable

This may be Solana's biggest challenge.

A blockchain can process billions of transactions, but high transaction numbers alone don't prove that the ecosystem is creating lasting economic value.

Solana has historically benefited from highly speculative activity. The challenge now is expanding beyond short-term trends into payments, stablecoins, tokenized assets, DeFi and applications that people continue using regardless of market hype.

In other words, Solana has proven that users can come.

Now it needs to prove that they will stay.

Can $SOL Capture the Value?

There is also an important difference between Solana succeeding as a network and $SOL succeeding as an asset.

If institutions use Solana for payments, settlement or tokenization, that increases the network's importance.

But investors will still watch whether growing network activity creates meaningful demand for $SOL itself through fees, staking and other economic uses.

This could become one of the most important questions surrounding $SOL in 2026.

Decentralization Still Matters

Solana's performance comes with trade-offs.

Running a high-performance validator requires serious infrastructure, and concerns around validator concentration and decentralization remain part of the discussion.

At the same time, Solana has been developing multiple validator clients, reducing dependence on one implementation and potentially making the network more resilient.

For institutions considering putting significant financial activity on-chain, speed isn't enough.

Reliability, decentralization and infrastructure diversity matter too.

The Next Phase Is About More Than Speed

Solana doesn't need another demonstration that it can process transactions quickly.

It needs to show that its technology can support valuable applications at scale for years, not just during periods of intense speculation.

Payments, stablecoins, tokenization and broader financial applications could provide that opportunity.

If Solana can combine its speed with reliable infrastructure, sustainable users and stronger economic value capture, its story becomes much bigger than simply being the "fast blockchain."

$SOL has already proven it can be fast. Now Solana needs to prove that speed can turn into lasting value.
