rewrite this title What is Solana (SOL)? How It Works, What It Does, and Why It’s So Fast

If crypto had a crowd favorite, it might just be Solana. It’s fast, cheap, and powers everything from memecoins to billion-dollar games. Here’s how Solana works, where it’s headed, and why so many are betting big on it.

What Is Solana?

Solana is a high-performance Layer-1 blockchain designed for speed, low fees, and real-world usability. It launched in 2020 and is now maintained by the Solana Foundation in Geneva. With a unique combination of proof-of-history and proof-of-stake, Solana processes thousands of transactions per second at a fraction of a cent each. It powers DeFi, NFTs, Web3 apps, and more—offering a fast, scalable alternative to Ethereum.

The Solana network handles thousands of transactions per second—with fees usually less than a penny per each. It is fast and cheap, which is what makes Solana a great fit for apps where every cent and second counts.Thanks to this performance, the Solana blockchain attracted thousands of developers and climbed into the top ten chains by market capitalization. It’s not without flaws—downtime and centralization issues have raised concerns. But for many users, the experience speaks for itself. Solana feels instant, affordable, and ready for anything.

What Makes Solana Unique?

Solana stands out thanks to its custom-built architecture designed for scale. It combines proof-of-history with proof-of-stake to process thousands of transactions per second with sub-second finality. Every transaction is pre-ordered by a cryptographic clock, reducing delays and boosting throughput.

This foundation makes Solana a high-performance blockchain suited for mass adoption. Its infrastructure supports emerging sectors like DePIN and AI, which demand speed, efficiency, and reliability.

The blockchain technology powering Solana is engineered to be censorship-resistant and globally accessible. With over 1,100 active validators and fast data propagation, the network remains both decentralized and lightning fast.

Solana’s tools are also dev-friendly. Developers can build using familiar languages like Rust, C, and C++. With scalable design and a thriving ecosystem, Solana continues to attract serious innovation.

Origin of Solana

Solana was founded in 2017 by Anatoly Yakovenko and the Solana team, many of whom had backgrounds at Qualcomm, Dropbox, and Intel. Yakovenko published the original whitepaper for proof-of-history that year, aiming to solve the time-sync issue slowing other blockchains.

The protocol was developed by Solana Labs, and its mainnet officially launched in March 2020—the first blockchain to use PoH in production. From the start, the focus was clear: speed, scale, and openness.

Solana raised funding from investors like Polychain Capital and built early infrastructure for wallets, validators, and tooling. As momentum grew, the Solana Foundation began hosting global hackathons to attract developers and fuel innovation.

By 2021, activity surged. Projects flooded in. SOL’s price skyrocketed. 

Today, Solana sits alongside Ethereum as one of the most used smart-contract platforms in crypto—with a thriving ecosystem built on speed and experimentation.

How Solana Works

Solana’s performance relies on two key pillars: a network of validators and its unique consensus algorithm, called proof-of-history.

Validators

Validators keep the network running. They operate nodes, process transactions, and secure the chain. To become one, a user must stake Solana’s native token—SOL—as collateral. The more SOL staked (either directly or through delegators), the higher the chance of being chosen to validate blocks. This system is called proof-of-stake.

Solana enhances speed by splitting work across “validator clusters” and pushing tasks off the main chain. Tools like Gulf Stream and Sealevel help run many transactions and smart contracts at once. In return, validators earn new SOL and a cut of fees—with a portion passed back to stakers. 

Proof-of-History (PoH) consensus mechanism

Proof-of-history is what makes Solana so fast. It enhances the efficiency of proof-of-stake by creating a shared clock for the network. Each event is logged as a verifiable sequence of cryptographic hashes, not just timestamps. This lets validators agree on transaction order instantly. 

Solana’s Performance Metrics

Solana is built for speed and cost efficiency. Its design allows it to scale while staying cheap—two major reasons for its popularity.

Transaction Speed and Scalability

Solana was made for massive throughput. It can theoretically hit 65,000 TPS and regularly handles thousands, even under pressure. It can process transactions in under a second, thanks to short block times and upgrades like Alpenglow (targeting 150ms finality). 

By contrast, Ethereum processes on the order of 15 transactions per second. This makes Solana perfect for fast-moving apps like games or auctions.

Network Fees and Efficiency

Solana’s transaction fees are tiny—often under $0.01. In fact, the average transaction fee is closer to $0.00026. This makes it ideal for NFTs, micropayments, or high-frequency trading. Plus, half of all fees are burned, helping stabilize the token’s economy.

Solana Ecosystem: What You Can Do

The Solana ecosystem is fast-growing, creative, and built for real-world use. It’s home to hundreds of apps across DeFi, NFTs, gaming, and payments—all powered by low fees and fast finality.

Decentralized Applications (dApps)

Solana runs thousands of smart contracts across its ecosystem. Popular dApps include Serum and Raydium (for token swaps), and Jupiter—a powerful DEX aggregator. Solana’s apps pulled in over $1.2 billion in revenue in Q1 2025, driven by trading and memecoin activity.

Decentralized Finance (DeFi) Platforms

You can lend, borrow, or trade with apps like Solend, Lendao, and MarginFi. Mango Markets was also a key player before its 2022 exploit. Solana’s high throughput makes it ideal for DeFi protocols that need speed and scale.

Non-Fungible Tokens (NFTs) and Marketplaces

Solana is known for fast, cheap NFT minting. NFT minting and trading on Solana platforms costs cents, whereas on Ethereum it can cost several dollars in gas. NFT marketplaces like Magic Eden and Solanart host top collections like Degenerate Ape Academy and SolPunks.

Gaming and Web3 Innovations

Game titles like Star Atlas, Aurory, and STEPN run on Solana. The network’s push into mobile-first Web3 includes the Solana Saga smartphone—a crypto-native device with an integrated wallet and dApp store.

What Is Solana For?

Solana serves multiple purposes, with its SOL token at the core:

1. Utility of SOL

SOL powers everything on the network. You use it to stake, vote, trade, and pay transaction fees. SOL is also the gas token for many DeFi and NFT platforms.

2. Paying for Transactions

Solana makes it easy to move value fast and cheap. You can send SOL or SPL tokens almost instantly, even across borders. Fees are near zero, which makes it perfect for micropayments, tipping, or merchant transactions through tools like Solana Pay.

3. Staking for Network Security

SOL holders can lock up tokens to help secure the network. Validators use that stake to validate blocks and earn rewards, passing most of it back to delegators. Staking also helps decentralize the system. As of mid-2025, Solana had 1,100+ validators—and staking remains a key pillar of DeFi participation.

Token Supply and Economics

Solana’s supply isn’t capped but grows slowly. Over 500 million SOL are circulating as of mid-2025. Inflation started at 8% but drops 15% yearly, targeting 1.5% long-term. Half of each transaction fee is burned, keeping supply in check.

SOL’s price is volatile—it peaked near $260 in 2021, dropping in 2022, and then rebounding by approximately 230% during 2024.

How Is Solana Different from Ethereum?

Solana and Ethereum are top contenders in smart contracts, but they follow different playbooks—especially when it comes to speed, cost, and infrastructure.

Ethereum remains more decentralized, but Solana focuses on scalability. Each reflects a different philosophy in the evolving cryptocurrency market—one prioritizing security, the other pushing the limits of performance.

Speed and Cost

Solana is much faster. It processes thousands of transactions per second, while Ethereum’s Layer-1 handles just 15–30. Finality on Solana takes less than a second; Ethereum averages ~12 seconds per block.

Solana’s fees are near zero—often under $0.01. Ethereum gas fees hover around $0.30 and spike higher under heavier loads.

This makes Solana a low-cost option for fast-paced apps. It’s also why Solana has gained traction in active DeFi trading—in 2024, it even surpassed Ethereum in daily DEX volume. While Ethereum still leads in developer tools and market cap, Solana appeals to builders who prioritize speed.

Sustainability

Both chains use proof-of-stake and are therefore energy-efficient. Solana has run this way since launch. Ethereum switched over in 2022.

Solana uses around 16.7 GWh/year

Ethereum now consumes roughly 2.6 GWh/year

That means Solana uses about 6.4× more energy annually than Ethereum overall, but still remains hundreds of times more efficient than proof-of-work chains like Bitcoin.

Per transaction, Solana averages just 0.004 Wh—about the energy of a single Google search—while PoW blockchains consume hundreds or thousands of times more.

Challenges of Solana Crypto

While it’s powerful and popular, there are a few important risks to consider.

1. Network Outages and Downtime

Solana has suffered multiple outages due to bugs and spam attacks. By 2024, it had experienced at least seven major halts. In April 2024, a flood of transactions overwhelmed validators, leading to hours of downtime. At peak congestion, up to 75% of transactions failed. The team has introduced fixes like priority fees and the Firedancer client, but reliability remains a concern—especially when, in comparison, Ethereum’s network has never fully gone down.

2. Centralization Concerns

The top three validators control 24% of all staked SOL. With high hardware requirements and strong influence from Solana Labs and the Solana Foundation, critics say control is too concentrated. The collapse of FTX—a major SOL holder—showed how fragile this centralization can be.

3. Security Vulnerabilities

Solana-based apps have been hacked for hundreds of millions in the past. In 2022, due the Wormhole bridge exploit alone, $326M was lost. Most issues come from buggy smart contracts, not the chain itself, but the risks are real.

4. Regulatory Risks

The SEC has flagged SOL as a potential unregistered security. Some platforms (like Robinhood) delisted it in 2023. While pressure has eased in 2025, the final decision is still pending.

The Future of Solana

Solana is evolving fast. Under the hood, upgrades like QUIC networking, the Firedancer validator client, and the upcoming Alpenglow release aim to slash block finality times to just 150 milliseconds. These changes are aiming to improve stability, scale, and speed—the three pillars Solana is doubling down on.

The platform is gaining serious traction. Stablecoin adoption on Solana jumped from $2.16 billion to over $12 billion in just one year. Visa and Shopify have already tapped into Solana for blockchain-based payments. That kind of momentum boosts its overall market value, drawing in both builders and businesses.

The ecosystem is expanding too. With 1,100+ validators and strong developer momentum, the Solana Foundation continues to host hackathons and fund new tooling. The network is growing across DeFi, NFTs, gaming, and mobile-first apps like the Solana Saga phone.

And the people are showing up. Community support is visible everywhere, from memecoins and social media to real-world giving: in 2025, SOL holders donated over $3.6 million to charities via The Giving Block.

If Solana keeps this pace while improving reliability, it could become the first choice for scalable Web3 infrastructure.

Final Thoughts

Solana is fast, cheap, and ambitious, but still young. It’s not perfect: network outages, centralization concerns, and volatile token prices are real. But the potential is huge.

If you’re here to build or explore Web3, Solana gives you a real playground. Just DYOR, stay cautious, and keep an eye on what comes next.
