A few months ago a friend of mine rang me out of the blue and asked me a question.
Can you explain crypto mining without all those complicated words?
Good question.
If you’ve ever searched the term “what is crypto mining” on google, you’ve probably seen articles start to throw around terms like hash functions, consensus mechanisms and cryptographic algorithms. Five minutes later you’re more confused than you were before.
So we won’t get into all that.
The simplest way to understand crypto mining is to forget the word mining for a minute because, honestly, it’s a terrible name.
No one is digging into the ground for Bitcoin. No one is pulling shiny digital coins out of a virtual cave.
What is really going on is far less dramatic but far more important.
Each time someone sends Bitcoin to someone else, the network needs to verify that the transaction is genuine. It must confirm that the sender owns those coins and hasn’t already spent them elsewhere.
That job would usually be done by a bank.
Bitcoin has no bank.
This is where the miners step in.
Imagine them as thousands of independent accountants scattered across the globe. They don’t know each other, they don’t work for the same company and nobody tells them what to do. And yet they all seem to agree on what transactions are valid. When a large enough group of them agrees, those transactions are inscribed into the permanent record of Bitcoin.
This is the essence of crypto-mining.
No magick. No money to spare. Just a clever way to keep a digital payment system honest.
What Miners Actually Do * Understanding
That’s what surprised me when I first heard about this.
Miners don’t spend their day ‘creating Bitcoin’ In fact most of what they do is not mint new coins.
Their real job is to check the transactions.
Think of a hundred people sending Bitcoin simultaneously. But before those checks can be cashed, somebody has to make sure it all adds up.
Bitcoin allows thousands of computers to compete for the job, rather than relying on one company to do that.
Each one gets the same list of pending transactions. Then they all get down to work on a mathematical puzzle that is deliberately difficult to solve, but easy for anyone else to check once it is solved.
It’s like opening a combination lock.
The first computer that gets the correct answer gets to say “I’ve verified this batch.”
Everyone else checks the solution. If that’s correct (and it usually is), that batch of transactions is added to the blockchain.
The miner who wins gets a reward for the work performed.
Then it all begins again for everyone.
And the whole thing takes place ten minutes apart every day without someone in an office pushing buttons.
