What Is Solana and How Does It Work?
A clear guide to Solana: the high-speed blockchain that rivals Ethereum on transaction throughput and has become a major platform for DeFi and NFTs.
Solana is a high-performance blockchain designed for speed and low cost. Where Bitcoin processes around 7 transactions per second and Ethereum around 15, Solana regularly handles thousands and is capable of significantly more.
The core idea
Solana was founded in 2017 by Anatoly Yakovenko, a former engineer at Qualcomm. His core insight was that most blockchain slowdowns come from the time validators spend agreeing on what the current time is.
His solution was a mechanism called Proof of History (PoH), which creates a verifiable record of time passing. By weaving timestamps directly into the chain, validators can process transactions in parallel without needing to wait for agreement on timing.
How fast is Solana?
In production, Solana processes around 2,000–4,000 transactions per second, with theoretical throughput far higher. Transaction fees average a fraction of a cent, making it practical for high-volume use cases like trading and gaming.
What is Solana used for?
Solana has become a major platform for:
- DeFi: Jupiter, Raydium, and Orca are among the largest decentralised exchanges operating on Solana.
- NFTs: Solana became one of the dominant NFT markets, with projects like DeGods and y00ts launching there.
- Memecoins: Solana’s low fees made it the preferred chain for memecoin trading in 2023 and 2024.
- Payments: Its speed and low fees make it more practical for everyday payments than Ethereum mainnet.
What are SOL tokens?
SOL is Solana’s native token. It is used to pay transaction fees and to stake in the proof-of-stake consensus mechanism. Validators and their delegators earn SOL rewards for securing the network.
Has Solana had problems?
Yes. Solana has experienced several high-profile network outages in its history, including extended periods where block production halted entirely. These events damaged its reputation, particularly among developers who need reliability.
The network has become significantly more stable in recent years, and the Firedancer upgrade (a second independent validator client) is seen as a major step toward the reliability of more established chains.
How does Solana compare to Ethereum?
Solana is faster and cheaper but has historically been less decentralised than Ethereum. Running a Solana validator requires expensive hardware, which limits who can participate. Ethereum’s validator requirements are lower, supporting a larger and more geographically distributed set of validators.
