Bitcoin has been all the rage lately, but how exactly does it work?
Before you go out and buy some bitcoins of your own, it helps to understand how the virtual currency works and how to mine those coins!
Read this post to learn all about the basics of Bitcoin mining and whether or not you can make money doing it yourself!
The 10 most important questions about bitcoin
Bitcoin mining is the process of adding transaction records to bitcoin's public ledger of past transactions. This process confirms the transactions and prevents double-spending.
It can also be used to transfer bitcoins between accounts.
1) Why does bitcoin mining need a lot of computing power?
2) How does bitcoin mining work?
3) What are proof-of-work blockchains?
4) Where do new bitcoins come from?
5) How do you mine for bitcoins?
What is the bitcoin price?
Bitcoin is a digital currency that is not tied to any country or central bank. Bitcoins are created, transferred and verified without the need for intermediacy from a central authority.
The transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain.
The bitcoin protocol uses an algorithm called mining to produce bitcoins at an ever-decreasing rate, which will eventually reach zero as the total number of bitcoin approaches 21 million.
What do you mean by mining?
Mining is the process by which transactions are verified and added to the public ledger, known as the blockchain.
The miners that accomplish this feat use their computers in order to solve complex mathematical equations and then receive a reward in Bitcoins for their efforts.
This process serves as a security measure, preventing fraudsters from compromising the network, as well as creating new Bitcoins all over again.
Why do you need special hardware for bitcoin mining?
Bitcoin mining is the process of adding transaction records to bitcoin's public ledger of past transactions.
Mining is done by running a computer program that searches for a specific hash, or a type of alphanumeric value.
The hashed value is created by running the input through a cryptographic hash function and turning it into an encrypted string of letters and numbers.
The miner then submits this string as proof-of-work (PoW) to the network, which judges its validity.
How much money can I make from bitcoin mining with my laptop or pc CPU alone?
You can earn a little bit of money mining bitcoin, but it's not really worth the time and effort. Mining bitcoin with your computer will probably not result in any significant profit.
For example, with a desktop computer you might be able to make $5 per month, which is barely enough for a single purchase at Starbucks.
If you have a laptop or PC CPU, you'll likely be able to make even less than that.
Where are bitcoins generated, exactly - during the creation of new blocks, or by solving difficult problems (using computing power)?
New bitcoins are generated by solving a difficult problem. A block is an entry in the blockchain which records some or all of the recent transactions, and once it's been added it can't be changed.
Blocks are created approximately every 10 minutes, and each one contains a difficult mathematical problem that a bitcoin miner has to solve.
The first miner who solves the problem gets a reward of 25 bitcoins, which they get to keep as long as they're the first one.
Can anyone mine bitcoins? Who gets newly created bitcoins, and who mines them first - these are all determined based on block rewards, right?
Bitcoin mining is the process by which new bitcoins are generated.
Mining a bitcoin can be done on a personal computer, as long as you have a fast processor and an affordable electricity bill - and then you're ready to start generating some bitcoin!
Every time someone sends bitcoins from one address to another, a transaction takes place, and this transaction gets recorded in the blockchain.
Miners use specialized computers that solve mathematical problems to produce each block of transactions, and whoever solves the problem first wins 12.5 bitcoins (a little less than US$100,000 at today's price).
When your computer finds the solution it shares it with other miners on its network who confirm it before accepting or rejecting it.
The miner that confirms first gets the reward of 12.5 bitcoins - but if they don't find the answer in 10 minutes they get nothing and somebody else tries their luck instead.
Does this mean that if I start mining bitcoins now, at some point I'll be able to earn half a million dollars per day / month / year without doing anything else but keeping my equipment running 24/7?? Sounds too good to be true...!
In order to understand the process, you should start with the basics.
Mining bitcoin means solving complex math problems and adding the transactions you receive.
When a miner solves a problem they are rewarded with bitcoins. The more problems that are solved, the harder it becomes to solve them and earn bitcoins.
Eventually, there will be too many miners trying to solve problems at the same time and no one will get anything out of it.
So how does this affect me? There are two ways in which this affects us:
Firstly by making mining unprofitable for everyone (not just those of us who started early)
Secondly by pushing miners towards less profitable coins instead of bitcoin.
