Chapter · Master Solana
Speed and tiny fees
On Solana a basic transaction usually costs a tiny fraction of a cent, and blocks are produced very fast, roughly every 400 milliseconds. Fees are measured in lamports, a tiny unit of SOL. One SOL is one billion lamports. Because each action is so cheap, you can trade, tip, or mint many times without a big bill, which is a core part of Solana's pitch.
Free to play. No ads, no token, no account needed to start.
What this lesson covers
The honest catch
Fast and cheap sounds perfect, but it puts heavy demands on the computers that run the network. Pushing so much data so quickly is exactly what has, at times, caused Solana to slow down or stop. Cheap fees can also invite spam, waves of low-value transactions that clog things up. We will cover both congestion and outages in later lessons.
What you get asked
How many lamports make up one whole SOL?
One SOL equals one billion lamports. Fees are so small that it helps to have a tiny unit, just like cents sit below a dollar.
Roughly how often does Solana produce a new block?
Solana targets very fast blocks, near 400 milliseconds. That quick pace is why actions feel close to instant compared with slower chains.
Solana fees are priced in ___, a tiny unit where one billion of them equals a single SOL.
Lamports are Solana's smallest unit, named after computer scientist Leslie Lamport. They let the network charge fees far smaller than a cent.
Why are super low fees important for the kinds of apps Solana wants?
When each action costs almost nothing, developers can build things like games, trading apps, and frequent payments where high fees would kill the experience.
