Mining pools

Together instead of alone

Building 8 min 6 cards 6 questions

Objectives

Alone you wait a long time

A single machine can go years without finding a block. Not because it is bad, but because its share of the network hashrate is tiny. The expected yield is still right, only the spread is unbearable.

A pool shares the risk

Operators join forces and search together. If one finds a block, the reward is split according to the computing power contributed.

Rare large hits become regular small amounts.

How the share is proven

Every participant sends the pool near misses: fingerprints that fall below an easier threshold. Its performance can be read off from those without it ever having found a real block.

What the pool does not own

A pool does not own the machines. It only coordinates and usually keeps one or two percent. Participants can switch at any time, and they do.

Why the distribution matters

If a single pool grows too large, so does its power over the order and selection of payments. With more than half the computing power, attacks would also be possible. That is why the distribution is watched.

What a pool cannot do

It cannot change the rules. A block that breaks them is rejected by the nodes, even if the largest pool built it.

Glossary

Pool
