Mining from 50K-Feet: What, Who & Why

September 02, 2020

This is a high-level, non-technical overview of what mining is, who does the mining, and why they do it. It serves primarily as a short-hand reference for those who need a refresher on mining basics, however, total beginners can also benefit from this elementary introduction. For more comprehensive introductions on mining concepts, check out our posts on mining and mining pools.

Mining and Miners

Mining is a consensus-building process. It’s how cryptocurrency networks stay secure and keep track of the network’s transaction history.

Networks are a bunch of interconnected computers that are constantly sharing information to ensure everyone’s records are up-to-date, accurate, and honest. Miners are like worker bees, validating these records (transactions) as true and storing them for safe keeping.

Just like bees need honey and pollen to build and protect the hive, miners need energy and computational power to connect to and secure the network. As a reward for their efforts, bees get shelter and protection. Similarly, miners are rewarded tokens (the cryptocurrency units) in exchange for making the network run how it’s designed to run.

Mining Ain’t Cheap

Miners are selfish. Their motivations to validate transactions and secure the network are not altruistic. Those are the table stakes to play the game. The real motivation is a chance to get a spoonful from the honey pot - the mining reward.

And for good reason. Mining ain’t cheap. Buying the miner (computer) is only the first step. Actually doing the mining (that is, dedicating computational power) is where the real costs are seen as energy bills add up.

Why?

The bigger the network, the higher the reward. The higher the reward, the more miners that want a piece of the action. More miners means more competition. And more competition means more computing power required to play the game.

Fortunately, there’s more than one way for miners to play the game. Check out Urkel’s mining pools post to learn more.
