Solana is a proof-of-stake Layer 1 blockchain built for speed. It settles thousands of transactions per second, each for a fraction of a cent. The trick behind it is a timekeeping idea called Proof of History. Its native token, SOL, pays the fees and secures the network, and the chain runs apps for DeFi trading, NFTs, and payments.
Solana went live in March 2020, created by Anatoly Yakovenko and Raj Gokal. It is a Layer 1, meaning a base blockchain that runs on its own network the way Bitcoin and Ethereum do. Its design bet is unusual: keep it all on one shared ledger, and make that ledger fast enough for daily use.
You have probably also heard the other half of the reputation: "Solana goes down." That was true from 2021 through early 2024. The story has since changed, and most explainers have not caught up. This guide covers both halves: the tech, the SOL token, and the uptime verdict as it stands in 2026.
Solana in one minute: a fast, low-cost blockchain
Solana was built to fix a specific problem: blockchains were too slow and too costly for everyday money. Anatoly Yakovenko, a former Qualcomm engineer, published the core idea in 2017. The network went live in March 2020 with a goal that sounded absurd at the time: handle payment-network traffic on one public chain.
The ambition needs context. Bitcoin settles roughly seven transactions per second. Both it and Ethereum get costly the moment demand rises, because users bid against each other for scarce block space. Yakovenko's insight was that the real bottleneck was time: blockchain computers waste most of their effort agreeing on when things happened. He teamed up with Raj Gokal to build the company around the idea. Engineers Greg Fitzgerald and Stephen Akridge joined as early builders.
A road analogy captures the design choice. Most blockchains ease congestion the way a crowded city does: they build toll roads around the center. These extra networks handle traffic on the side and settle back to the main chain later. Solana instead built one very wide highway and raised the speed limit, so all traffic stays on the same road. The single-road design has a second benefit beyond speed. Every app on Solana shares one ledger, so apps can work together instantly, with no bridges between side networks.
The speed limit on that highway comes from an unusual idea about time, and it is worth two minutes to understand.
The idea that makes Solana fast: Proof of History
Proof of History is a built-in clock for the blockchain. Each event gets a stamp that proves what came before it, so the computers running Solana can agree on the order of events without stopping to compare notes. That one change removes most of the waiting that slows older chains down.
Picture a notary with a numbered stamp that only counts upward. Every page that crosses the desk gets the next number. Anyone can later check that page 500 was stamped after page 499 without asking the notary a single question. Proof of History works like that stamp. A running chain of hashes acts as a public stopwatch, and events written into it carry proof of their own place in time (source: Anatoly Yakovenko's Solana whitepaper).
One common mix-up is worth clearing early: Proof of History is not how Solana reaches agreement. Solana is a proof-of-stake network. Validators, the computers that check transactions, lock up SOL as collateral. They vote on the state of the chain through a system called Tower BFT (source: Tower BFT: Solana's implementation of PBFT). The clock does not replace the voting; it makes the voting fast, because nobody argues about what happened first.
Here is what happens when you send a transaction:
- You tap send in your wallet, and the transaction is signed with your private key.
- It travels straight to the current leader, the validator whose turn it is to build the next block. Turns are scheduled in advance, which the shared clock makes possible.
- The leader stamps your transaction into the running sequence and executes it alongside thousands of others in parallel.
- Other validators verify and vote, and your transfer is confirmed about a second later.
The full mechanics deserve their own article, and Blofin's guide on how Proof of History works walks the clock design step by step. Day to day, though, what you notice is the cost and the wait.
How fast and how cheap is it, really?
A simple Solana transfer usually costs around $0.00025 in base fees and confirms in about a second. New blocks arrive roughly every 400 milliseconds. Fees can rise when an app gets busy, because users add small priority tips to jump the queue. Even busy-day costs usually stay under a cent.
The base fee is a fixed, tiny amount set by the network rather than an open auction (source: Solana Foundation's What is Solana guide). Here is how that compares with the two chains most newcomers know. The figures are typical mid-2026 ranges, not best-case claims:
| Network | Typical cost to send funds | Time until you can count on it |
|---|---|---|
| Solana | around $0.00025 base fee, plus optional priority tips | about 1 second |
| Ethereum (base chain) | typically well under $1 in quiet periods, several dollars at peaks | seconds to include, minutes to fully settle |
| Bitcoin | roughly $0.50 to $5, swinging with demand | about 10 to 60 minutes |
Fees on every network move with congestion, so treat these as ranges, not promises. A worked example makes the difference concrete. Say you send a friend $50 in a stablecoin on Solana. The friend sees the full $50 about one second later, and the network's cut is a few hundredths of a cent. At the typical base fee, you could repeat that transfer 4,000 times before your combined fees reached one dollar. On Bitcoin or Ethereum's base chain, a single busy-day transfer can cost more than all 4,000 of those Solana fees combined.
One caution: marketing decks sometimes cite six-figure best-case peaks per second, while real daily throughput runs in the low thousands. Even the lower figure is far beyond what Bitcoin or Ethereum's base chain settles. Every one of those transactions, cheap as it is, gets paid for in a single asset: SOL.
What the SOL token actually does
SOL is Solana's native token, and it has three jobs. It pays every fee on the network and secures the chain when holders stake it with validators. It is also the base money that Solana's apps price things in. Using Solana at all means holding at least a little SOL.
The fee job is the simplest: every transaction spends a little SOL, the way every car trip burns a little fuel. Half of each base fee is destroyed for good, which slightly offsets new issuance.
The security job is called staking. Anyone holding SOL can lock it with a validator to back that validator's honesty. In return they earn a share of the new SOL the network issues. Yields sit in the mid-single digits at recent rates, and they are designed to fall slowly. That is because new-SOL issuance started at 8% a year and steps down toward a long-run 1.5%. SOL has no hard supply cap, unlike Bitcoin's fixed 21 million. It ranks among the largest crypto assets by market value (source: CoinGecko's Solana page).
The third job is the quiet one. SOL is the default collateral and pricing asset across Solana's apps, much as ETH is on Ethereum. When you trade or lend on Solana, SOL is usually somewhere in the plumbing.
This guide stays on the "what" side of the line. If you want the practical side, Blofin's walkthrough on how to buy Solana covers venues and steps without the hype. Before any of that, though, most newcomers ask the harder question: can you trust this network to stay up?
Is Solana reliable now? The outage story, honestly
The outage reputation was earned: Solana halted repeatedly between September 2021 and early 2024, with the last full outage on February 6, 2024. It has run without a complete halt since. The root causes were engineered away with real fee markets, better traffic control, and a second validator client.
The record is public, and this guide sets it out in full (source: Helius's complete history of Solana outages):
| When | What happened | Root cause, in plain words |
|---|---|---|
| September 2021 | roughly 17-hour halt | bot traffic from a token launch flooded the network |
| 2022, several incidents | repeated halts and slowdowns | NFT-mint bot floods and software bugs in the single client |
| February 2023 | extended outage, restart required | a validator's faulty block-forwarding add-on broadcast one oversized block that overwhelmed the network |
| February 6, 2024 | roughly 5-hour halt, the last full outage to date | a bug in legacy code stalled block production |
Two structural weaknesses sat under all of it. First, spam was nearly free. When fees are a fraction of a cent and there is no queue pricing, a bot can drown the network for pocket change. Second, every validator ran the same software, so one bug was everyone's bug.
The fixes attacked both. Local fee markets and priority tips made spam expensive. They also confine congestion to the busy app instead of the whole chain. New networking rules, including a protocol called QUIC and stake-weighted traffic priority, gave the network a working front door. The deepest fix was client diversity. Firedancer, an independent validator client rebuilt from scratch by Jump Crypto (source: Jump Crypto's Firedancer page), went fully live on mainnet in December 2025 (source: Datawallet's Firedancer guide). As of mid-2026 it runs on roughly a fifth of validators, and some dashboards show more. A bug in one client no longer means the whole network stops. The incident-by-incident detail lives in Blofin's review of Solana's outage history.
From Blofin's operational perspective as an exchange running live SOL markets, the change that actually mattered was client diversity rather than any headline throughput figure. Across 2024 to 2026 we watched the network's failure mode shift from "a single-client bug can halt the chain" to a multi-client production system. That shift completed once full Firedancer reached mainnet. For anyone whose deposits, withdrawals, or open trades depend on the network staying up, that is the upgrade worth understanding.
Since that last halt, the network's trailing uptime has been effectively 100% into mid-2026. Staying up, though, only answers the first question. The next one is what people use the network for.
What people actually use Solana for
People use Solana for DeFi trading, NFTs, payments, memecoins, and DePIN networks that reward real-world devices. The common thread is cost. When a transaction settles for a fraction of a cent, whole kinds of apps become workable that pricier chains would shut out.
Payments show the logic most clearly. Sending $5 or $5,000 in a stablecoin costs the same fraction of a cent and arrives in about a second. That makes small transfers and cross-border payouts practical in a way a $3 fee never allows. DeFi is the second pillar. Solana hosts exchanges that update prices and orders thousands of times a minute. That style of trading only works when each tiny update is nearly free.
NFTs found a similar opening. Minting a digital collectible on Solana costs cents, so an artist can sell $5 pieces without the fee eating the price. A newcomer should also know that a large share of Solana's daily traffic is speculative memecoin trading. That demand is real, and it stress-tests the network, but it is still speculation.
The newest category is DePIN, short for decentralized physical infrastructure. These are networks of real devices, such as wireless hotspots or mapping dashcams, whose owners earn small token rewards. Paying thousands of devices a few cents each only works on a chain where the payout does not cost more than the reward. A network this busy invites one comparison above all.
Solana vs Ethereum, in brief
Solana and Ethereum attack the same problem from opposite directions. Ethereum keeps its base chain slow and steady, and pushes cheap, fast activity out to Layer 2 networks built on top. Solana makes the base chain itself fast enough for everything. The trade is raw speed versus a longer track record.
| Solana | Ethereum | |
|---|---|---|
| Scaling approach | one fast base chain | slower base chain plus Layer 2 networks |
| Typical fee to transact | a fraction of a cent | cents on Layer 2s, under $1 to several dollars on the base chain |
| Confirmation feel | about a second | seconds on Layer 2s, minutes on the base chain |
| Live since | March 2020 | July 2015 |
Neither approach has "won," and each carries costs the other avoids. Ethereum users juggle bridges between layers. Solana asks more of its validators' hardware, which feeds a running debate about how spread out the network really is. The full comparison, including security assumptions and developer culture, lives in Blofin's guide on Solana versus Ethereum. What remains is the current state of play.
Where Solana stands in 2026
In 2026, Solana runs on two separate validator clients, with Firedancer live on mainnet since December 2025. U.S. spot Solana ETFs have traded since late October 2025 (source: Bitwise's BSOL launch announcement). The next major upgrade, Alpenglow, is still in testing with a late-2026 mainnet target, so treat it as planned rather than live.
The client milestone is the one engineers care about. Blofin's explainer on the Firedancer client covers why a from-scratch rebuild matters more than any single feature. Alpenglow, the consensus redesign now in testing, aims to cut wait times well below the current second. No date is a promise in protocol work, and any claim that Alpenglow is already live is wrong as of mid-2026.
The ETF listing matters more for finance than for the tech: it put SOL price exposure inside normal brokerage accounts. On the builder side, Token-2022, also called token extensions, is the current standard for issuing new tokens. It builds in options like transfer fees and private balances that older tokens needed workarounds for.
Some risks remain. Fees can still spike during frenzies, so the "fraction of a cent" experience is typical rather than guaranteed. Validator hardware demands keep the debate about network spread alive. And the clean uptime record is measured in years, not decades. Solana in 2026 is a fast and steadily hardened network that has outgrown its worst years but not yet outgrown scrutiny.
Frequently asked questions
Is Solana a coin or a blockchain?
Solana is the blockchain; SOL is the coin that runs on it. When a headline says "Solana is up 5%," it means the SOL token's price, because a network itself has no price. The split matters when you read news: ETFs and staking yields concern the SOL token, while outages and upgrades concern the Solana network. Wallets and exchanges list the asset under the ticker SOL.
Who created Solana and when?
Anatoly Yakovenko published the Proof of History idea in late 2017 and co-founded Solana Labs with Raj Gokal. The mainnet launched in March 2020. Two groups now share the work: Solana Labs builds the core software, while the Swiss nonprofit Solana Foundation funds builders and outreach. The name has nothing to do with the tech. It comes from Solana Beach, California, where the founders once lived.
Why are Solana transactions so cheap?
The base fee is fixed and tiny by design, not set by an open bidding war. The network also processes many transactions side by side, so demand for one app does not raise costs for everyone else. When one corner of the chain gets busy, local fee markets raise costs for that app's users only. Everyone else keeps paying a fraction of a cent. Cheap fees are an engineering target rather than a promotion, so they do not expire.
Has Solana fixed its outage problems?
Largely, yes. The last full outage was February 6, 2024, and the network has since run through several high-traffic frenzies without a complete halt. The confidence rests on engineering, not luck. Spamming the network is now expensive, and a second validator client removed the single point of failure behind most of the old halts. No public blockchain can guarantee uptime, but a multi-year clean record under load is as strong as the evidence gets.
Can you stake SOL, and what is the yield?
Yes. Staking SOL earns roughly 5% to 6% a year at recent rates, net of validator commissions. The range is designed to drift lower as the network's issuance schedule steps down. One nuance is easy to miss: Solana has no slashing live on the network today. A rule called SIMD-0204 added evidence-logging groundwork for future penalties, so "your stake cannot be cut" describes the current state, not a lasting promise. The process is covered in Blofin's guide on how to stake SOL for rewards.
Is there a Solana ETF?
Yes. Spot Solana ETFs have traded on U.S. exchanges since late October 2025. They let investors take SOL price exposure through a normal brokerage account. An ETF share is a claim on a fund that holds SOL, not SOL itself. Most of these funds stake their SOL and pass a share of the yield through, but you cannot use the shares on-chain, and the fund charges a yearly fee. Which route makes sense depends on whether you want to use the network or simply track the price.
