What Solana is and how it differs from Bitcoin and Ethereum
Solana is a blockchain network that processes cryptocurrency transactions. Unlike Bitcoin, which prioritizes security through a slower verification process, or Ethereum, which runs applications alongside payments, Solana is built to process transactions as quickly as possible. It does this by using a method called Proof of History, which creates a timestamped record of events before they are verified, rather than verifying each transaction one at a time.
The Solana network has its own cryptocurrency, also called SOL. You can hold SOL in a digital wallet, trade it on exchanges, or use it to pay transaction fees on the network. The network launched in 2020 and is maintained by a network of computers (called validators) that process and verify transactions.
Solana's main trade-off is speed for decentralization. Because it processes transactions so quickly, it requires more powerful computers to run validators, which means fewer people can afford to operate one. Bitcoin and Ethereum have more validators spread across more locations, which some argue makes them more resistant to control by any single entity.
Key Takeaways
- Solana is a blockchain network designed to process transactions faster than Bitcoin or Ethereum by using a timestamping method called Proof of History.
- SOL is Solana's native cryptocurrency, used to pay transaction fees and held as an investment by people who believe the network will grow.
- Solana validators require expensive hardware, so fewer people run them compared to Bitcoin or Ethereum, which affects how decentralized the network is.
- The Solana network has experienced outages where validators stopped processing transactions, which raised questions about its reliability compared to older blockchains.
- You can buy SOL on cryptocurrency exchanges, but the price fluctuates based on market demand and network developments, just like other cryptocurrencies.
How Solana processes transactions differently
Solana uses Proof of History to create a historical record of when transactions occurred before validators verify them. This is different from Bitcoin's approach, where each transaction must be verified in order before the next one can be checked. With Proof of History, multiple transactions can be verified at the same time because the network already knows the order they happened in.
This design allows Solana to theoretically process thousands of transactions per second. In practice, the network has handled between 400 and 700 transactions per second during normal operation, though it is designed to scale higher. Bitcoin processes about 7 transactions per second, and Ethereum processes about 12 to 15 per second on its main network.
The trade-off is that Solana's validators need more computing power and faster internet connections to keep up with the speed. This makes it more expensive to run a validator, which limits how many people can participate in securing the network. Fewer validators can mean the network is more vulnerable to decisions made by a smaller group of people.
What SOL is and how it works
SOL is the cryptocurrency native to the Solana network. When you hold SOL, you own a digital asset stored in a cryptocurrency wallet. The price of SOL changes based on supply and demand in the market — if more people want to buy SOL than sell it, the price goes up, and vice versa.
SOL is used for two main purposes on the Solana network. First, it pays transaction fees when you send money or interact with applications built on Solana. These fees are much smaller than fees on Ethereum, which is one reason developers build applications on Solana. Second, SOL holders can stake their coins, meaning they lock them up to help validate transactions and earn rewards in return.
You can buy SOL on cryptocurrency exchanges like Coinbase, Kraken, or Binance using U.S. dollars or other cryptocurrencies. Once you own SOL, you can hold it in a self-custody wallet (where you control the private keys), keep it on an exchange, or stake it through a staking service. The price of SOL is not fixed — it has ranged from under $2 to over $200 depending on market conditions and network developments.
Why Solana experienced network outages
Between 2021 and 2022, the Solana network experienced several outages where validators stopped processing transactions for hours at a time. The most notable outage lasted about 17 hours in September 2022. During these outages, users could not send transactions or access their money, even though the blockchain itself was still running.
The outages happened because the network's validators became overwhelmed by the volume of transactions and requests they were receiving. When validators could not keep up, they fell out of sync with each other, and the network stopped producing new blocks. This is different from Bitcoin or Ethereum, which have not experienced network-wide outages of this kind.
Solana's developers have worked to improve the network's stability since these outages. However, the incidents raised questions about whether Solana's focus on speed comes at the cost of reliability. Some people argue that a slower network that never stops is more useful than a faster network that occasionally halts.
How Solana compares to other blockchains
| Feature | Solana | Bitcoin | Ethereum |
|---|---|---|---|
| Transactions per second | 400–700 (designed for higher) | ~7 | ~12–15 |
| Transaction cost | Fractions of a cent | $1–$50+ depending on demand | $5–$100+ depending on demand |
| Primary use | Fast payments and applications | Store of value, payments | Applications and smart contracts |
| Validator hardware requirement | High (expensive computers) | Low (can run on older hardware) | Medium (more accessible than Solana) |
| Network outages | Yes, multiple in 2021–2022 | No major outages since launch | No major outages since launch |
Solana is faster and cheaper than Bitcoin and Ethereum, which makes it attractive for applications that need to process many transactions quickly. However, Bitcoin has been running without interruption since 2009, and Ethereum has been stable since 2015. Solana is newer and has experienced reliability issues that older networks have not.
Bitcoin is primarily used as a store of value — people buy it hoping the price will increase over time. Ethereum is used both as a store of value and as a platform for building applications like decentralized finance (DeFi) services and NFT marketplaces. Solana is also used for applications and DeFi, but its main selling point is that these applications can run faster and cheaper than on Ethereum.
Risks and considerations for SOL holders
The price of SOL is volatile. It has dropped 80% or more from its peak multiple times. If you buy SOL as an investment, you should be prepared to lose some or all of that money. Cryptocurrency prices are driven by sentiment, news, and speculation, not by the underlying value of the network itself.
Solana's network has experienced outages, which means there is a risk that you could not access your SOL or complete transactions at critical moments. While the developers are working to improve stability, the network is younger and less proven than Bitcoin or Ethereum.
If you hold SOL in a self-custody wallet, you are responsible for protecting your private keys. If you lose your keys or they are stolen, your SOL is gone permanently. If you hold SOL on an exchange, you are trusting that exchange to keep your coins safe — if the exchange is hacked or goes out of business, your SOL could be lost.
Frequently Asked Questions
Is Solana a good investment?
That depends on your risk tolerance and investment goals. SOL is a volatile asset that has lost significant value multiple times. Some people believe Solana's speed and low fees will make it widely used, which could increase the price. Others think the network's outages and centralization concerns make it riskier than Bitcoin or Ethereum. You should research the network yourself and only invest money you can afford to lose.
Can I mine Solana like Bitcoin?
No. Solana uses Proof of History and Proof of Stake, not Proof of Work like Bitcoin. You cannot mine SOL with specialized hardware. Instead, you can stake SOL by locking it up to help validate transactions, and you earn rewards in return. Staking requires less electricity than mining but still requires you to lock up your coins for a period of time.
What happens if Solana's network shuts down?
If the Solana network permanently shut down, SOL would likely become worthless because the cryptocurrency would have no network to operate on. However, Solana is maintained by a large community of developers and validators who have financial incentives to keep it running. The risk of a permanent shutdown is low, but it is not zero.
How do I buy Solana?
You can buy SOL on cryptocurrency exchanges like Coinbase, Kraken, Binance, or Kraken by creating an account, verifying your identity, and linking a bank account or payment method. Once you buy SOL, you can hold it on the exchange or transfer it to a digital wallet that you control. Prices and fees vary by exchange, so it is worth comparing a few before you buy.
Is Solana decentralized?
Solana is less decentralized than Bitcoin or Ethereum because its validators require expensive hardware, which limits how many people can run one. However, Solana still has hundreds of validators spread across different locations and organizations, so no single entity controls the network. Decentralization exists on a spectrum, and Solana is somewhere in the middle.
