Solana is the fastest major Layer-1 blockchain, built to handle thousands of transactions per second at a fraction of a cent each. That speed has made it the go-to chain for trading, payments, and consumer apps, and SOL one of the largest cryptocurrencies. This review covers what Solana is, how it hits those speeds, the honest reliability story, and how to buy and stake SOL.
What is Solana?
Solana is a Layer-1 blockchain launched in 2020 by Anatoly Yakovenko and a founding team. Where Ethereum scales mainly through Layer-2 rollups, Solana scales the base layer itself, targeting thousands of transactions per second with sub-second finality.
That performance has made it a popular home for high-frequency use cases: decentralised exchanges, payments, memecoins, and consumer-facing apps that would be too expensive to run on Ethereum’s base layer. SOL is Solana’s native token, used to pay fees and to stake for network security.
How Solana achieves its speed
Solana’s headline feature is throughput, and it gets there by combining standard proof-of-stake with a unique innovation.
- Proof of History (PoH). A cryptographic clock that timestamps transactions before they enter the ledger, so validators agree on order without slow back-and-forth messaging. This is the core trick behind Solana’s speed.
- Proof of Stake. Validators stake SOL to secure the network and are chosen to produce blocks in proportion to their stake.
- A high-performance validator client. Parallel transaction processing lets the network use modern multi-core hardware fully.
| Property | Detail |
|---|---|
| Supply model | Inflationary, disinflationary schedule trending toward ~1.5% |
| Consensus | Proof-of-Stake + Proof of History |
| Throughput | Thousands of transactions per second |
| Typical fee | A fraction of a cent |
| Staking | SOL holders stake or delegate to validators for rewards |
Solana’s inflation began higher and decreases over time toward a long-term rate. Staking rewards offset that issuance for holders who stake, which matters because unstaked SOL is gradually diluted.
Solana vs Ethereum
The two are often framed as rivals, but they made opposite design choices.
| Property | Solana | Ethereum |
|---|---|---|
| Scaling approach | Fast base layer | Layer-2 rollups |
| Speed | Thousands of TPS, sub-second | Base layer slower, L2s fast |
| Fees | Fraction of a cent | Higher on base layer |
| Decentralisation | Fewer, heavier validators | Many lighter nodes |
| Trade-off | Raw performance | Maximum decentralisation |
Neither is strictly better. Solana optimises for speed and cost, Ethereum for decentralisation and security. Many investors hold both.
Ecosystem and reliability
Solana has one of the most active ecosystems in crypto, particularly strong in trading, payments, and consumer apps. Its main historical knock has been network reliability. Earlier years saw several full or partial outages under heavy load, which was a genuine black mark.
The network has since invested heavily in client diversity and stability, and uptime has improved markedly. The arrival of a second independent validator client was a major step, since it removes a single point of failure. Reliability is still a fair question to weigh, but the trajectory has been clearly upward.
Pros and cons
Strengths
- Extremely fast and cheap transactions, ideal for active on-chain use.
- A large, fast-growing ecosystem of apps and users.
- Native staking yield for SOL holders.
- Strong momentum in payments and consumer crypto.
Risks
- A history of network outages, though materially improving.
- Higher hardware requirements for validators raise decentralisation questions.
- Inflationary supply dilutes holders who do not stake.
- Higher volatility than Bitcoin or Ethereum.
Where to buy and how to stake SOL
SOL trades on all major venues, including Binance, Coinbase, and Kraken. New to buying crypto? Our how to buy crypto guide walks through it. After purchase you can:
- Self-custody SOL in a wallet such as Phantom, Solflare, or a hardware wallet. See our wallets guide.
- Stake by delegating to a validator directly from most Solana wallets to earn rewards.
- Hold on an exchange for convenience, accepting that you do not control the keys.
Staking on Solana is non-custodial when done from your own wallet. You keep control of your keys while delegating, and there is no long lock-up. Our staking guide covers the details.
Frequently asked questions
Is Solana a good investment? Solana is a leading high-throughput Layer-1 with strong adoption, but it is a higher-volatility altcoin than Bitcoin or Ethereum. Weigh the improving-but-imperfect reliability record and your own risk tolerance.
How is Solana different from Ethereum? Solana scales its base layer for raw speed, while Ethereum scales through Layer-2s and prioritises base-layer decentralisation. Solana is faster and cheaper today; Ethereum is more decentralised and has a larger ecosystem.
Can I stake SOL myself? Yes. Most Solana wallets let you delegate SOL to a validator in a few clicks while keeping custody of your coins, with no long lock-up period.
Why has Solana had outages? Its high throughput and low fees can attract bursts of automated traffic that overwhelmed earlier versions of the network. Client improvements and a second validator client have made outages far less frequent.
Does SOL have a maximum supply? No. Solana is inflationary, but the issuance rate declines over time toward a low long-term level, and staking rewards offset dilution for those who stake.
