# Why single pools keep Cardano strong

When a few big operators run hundreds of pools, the whole network gets weaker. Here is why your choice of pool matters, in plain words.


When you pick a stake pool, you are not only choosing who shares rewards with you. You are also helping decide **who runs Cardano**. This guide explains why that matters and what a "single pool" is.

## What a single pool is

Some stake pools are run by big companies, like exchanges or large staking businesses. One company can run dozens, sometimes hundreds, of pools under different tickers.

A **single pool** is a pool whose operator runs only that one pool. It is often one person or a small team, somewhere in the world, running servers they look after themselves.

On CardanoPools.com, pools that belong to a known group show the group name. Pools with no group show the tag **single**. The list shows only single pools by default.

## Why it matters: who makes the blocks

A blockchain stays honest because **no single party controls enough of it** to cheat. On Cardano, pools make blocks in proportion to the stake behind them. If one company controlled a big share of all stake, it could:

- slow down or skip transactions it does not like,
- put pressure on the rest of the network,
- become a single point of failure if its systems break or a government steps in.

Nothing like this needs to happen for the risk to be real. Decentralization is about making sure it **cannot** happen.

## The "Nakamoto coefficient"

People sometimes measure decentralization with one number: the smallest number of operators who together control more than half of all stake. The higher this number, the safer the network.

Every time someone moves stake from a giant operator to a small independent one, that number can go up. Your delegation is a vote for how Cardano is spread out.

## Do you earn less in a single pool?

Usually no. Rewards depend on the pool's fees and on luck, not on who runs it. A well-run single pool with 0% margin and the minimum fixed fee can pay **as much or more** than a big pool.

The one real difference is **luck over short periods**. A small pool may not make a block every epoch, so its rewards can jump around. Over months, it evens out. You can see how many blocks a pool has made on its page.

## What you can do

- Choose a single pool instead of the biggest name in your wallet.
- Check that the pool meets its pledge and is not saturated.
- Look at the **Need delegators** button on the [pool list](/). It shows the smallest working single pools first, where your stake makes the biggest difference.
- Tell a friend. Most people just accept whatever their wallet shows first.

Cardano was built so that ordinary people can run it. Choosing a single pool keeps it that way.
