What Is Solana and How Is It Different From Ethereum? A Plain-Words Guide

You send a few dollars of crypto. On one network the fee is a fraction of a cent. On another it can be a few dollars. Both are called "blockchains". So what is actually different?
This post compares Solana vs Ethereum in plain words. We cover speed, fees, how each one works, and the biggest argument people have about Solana: its outages.
Figures below come from web search summaries read on 19 October 2026. We could not open the official Solana status page or Ethereum dashboards from our research environment, so treat numbers as approximate and check the primary sources yourself.
Solana is a blockchain, meaning a shared record book that many computers keep in sync. People use it to send money, trade tokens and run apps. Its own coin is called SOL.
Ethereum does the same job, and it came first. Its coin is ETH. Both let developers build apps on top, which is why they get compared so often.
A block is a batch of transactions added to the record book. The shorter the wait between blocks, the faster you see your transaction confirmed.
A comparison table from Koinly (updated May 2026) lists Solana blocks at about 400 to 600 milliseconds. It lists Ethereum blocks at about 12 to 14 seconds.
That is a big gap. It comes from two different designs, which we look at next.
Solana's base fee is 5,000 lamports per signature, according to Banxa. A lamport is one billionth of a SOL, so that is 0.000005 SOL. Koinly puts the average Solana fee at about $0.00025.
Ethereum fees work like an auction. You bid a "gas price" to get ahead in the queue, so the fee rises when the network is busy. Koinly lists a typical Ethereum fee at roughly $0.15 to $0.50.
One caution. Much of Ethereum's everyday activity has moved to cheaper side networks. We explain how in our layer 2 rollups guide. So the "Ethereum is expensive" picture is only true for the main network.
Every blockchain needs its computers to agree on the order of transactions. Without that, two people could spend the same coin.
Ethereum uses proof of stake. Owners lock up ETH as a deposit, and they earn rewards for checking transactions honestly. Koinly says this switch, called The Merge in 2022, cut Ethereum's energy use by about 99.95 percent.
Solana also uses proof of stake. It adds a trick called Proof of History. Think of it as a built-in clock. It stamps each transaction with a time, so the order is already settled before validators vote. Banxa and Koinly both credit this design for Solana's fast blocks.
Speed has a price. Solana has had times when the whole network stopped and had to be restarted by hand.
Banxa mentions a 17-hour outage in September 2021. Decrypt covered a halt on 6 February 2024. Sources disagree on the dates and lengths of some older outages, so we do not list them all.
The newer news is calmer. Solana Compass reported in August 2026 that there had been no network-wide halt since 6 February 2024. That is a single source, and we could not check it against Solana's official status page. Verify it before you rely on it.
Why did halts happen? Sources point to heavy traffic and software bugs. Solana also asks validators to run powerful computers. Critics say that makes the network more centralized, meaning fewer people can run it. Supporters say the design trades some of that for speed.
Jump Crypto has been building a second validator program called Firedancer, so one bug cannot stop every computer at once. A search summary said it has been rolling out to mainnet validators during 2025.
Neither is "better". They make different trade-offs.
| Solana | Ethereum | |
|---|---|---|
| Block time | About 0.4 to 0.6 seconds | About 12 to 14 seconds |
| Typical fee | Fraction of a cent | About $0.15 to $0.50 on the main network |
| Agreement method | Proof of stake plus Proof of History | Proof of stake |
| Known weak spot | Past full-network halts | High fees when busy |
| Coin | SOL | ETH |

Both coins swing a lot. A faster network does not mean a safer investment. We make no prediction on price and nothing here says to buy or sell either coin.
What you can do is measure the swings. Volatility, the size of price moves, is something you can read for any coin.
Do not rely on a blog to judge how wild each coin is. Open Explore on NetWort and look up SOL and ETH side by side. Compare their volatility and drawdown (the biggest fall from a peak) with your own eyes before you decide how much either fits your plan.
