Bitcoin mining is the process of verifying bitcoin transactions, and adding them to the blockchain, the public ledger that bitcoin is based on. This process keeps the bitcoin network secure and creates new bitcoin as well.
When you want to send, spend, or receive bitcoin there is work to be done. Accounts have to be verified, the transaction needs to be made, and the blockchain needs to be updated and okayed by everyone on the bitcoin network. This is where bitcoin miners come in.
The process of bundling transactions, verifying them and adding them to the blockchain is what mining is all about. Miners do this work because they are rewarded for it. They get paid in bitcoin for every block added to the block chain and every transaction they process. Mining releases new bitcoin into the system and miners are paid in these newly made bitcoins.
There are many miners out there, all competing to add the next block to the blockchain and release new bitcoin. Right now about 18.5 million bitcoin have been released. This process will continue until roughly 2140 when all the 21 million bitcoin have been made. After that miners will be paid in transaction fees but there won’t be any new bitcoin made. There will only ever be 21 million bitcoin.
Mining gets harder the more miners there are and the pay out for mining a block gets smaller as more blocks are mined. When bitcoin started the reward for mining one block was 50 bitcoins. Today it is 6.25 bitcoins. The block reward gets cut in half every 210,000 blocks or every four years or so. This is known as ‘the halvening’. This keeps bitcoin’s supply low, keeping bitcoin rare, protects against inflation and will potentially make bitcoin more valuable over time. You can watch the count down to the next one at thehalvening.com.
Two things have to happen for a bitcoin miner to earn bitcoins. The first is they must verify one megabyte (MB) worth of transactions. This technically could be just one transaction but more likely will be several thousand transactions. The second thing that has to happen before a miner is rewarded and a block of transactions is added to the block chain, is miners have to solve an extremely difficult math problem called “proof of work”. What they are trying to do is guess a number that is the same or less that a number randomly created by the bitcoin network called a target hash. It sounds easier than it is. The target hash is a 64 digit hexadecimal number. Here’s an example:
As you can see it’s a huge number and it’s a real gamble trying to guess it. You have roughly a 1 in 18 trillion chance of guessing correctly on your first try. In fact you are 45,000 times more likely to win the Powerball Lottery. That’s why you need very specialized, very powerful computers called ASIC computers to do the guessing. Because this guess work is so difficult groups of miners will often combine their computing power in a mining pool and split the mining reward between them. Most blocks are now mined by pools. In fact most of bitcoin’s computing power comes from mining pool and large companies based in China. No one know exactly but it’s estimated that 65% of bitcoin mining happens there.
Here are the big take aways for bitcoin mining:
Mining verifies, secures, and maintains the blockchain in a decentralized way.
Mining creates new bitcoin by solving very difficult computational puzzles and rewards the miners for their work.
Here are the all the factors involved in mining bitcoin. Hash rate, block reward, mining difficulty and mining difficulty increase, electricity cost, power consumption, pool fees, and bitcoin’s price.
If you’re interested in mining bitcoin here’s how you get started.
Calculate the profitability – you will need to consider the factors mentioned above. Once you have all your numbers in hand you can find many mining profitability calculators
Buy mining hardware – You will need a specialized mining rig. Expect to pay between several hundred and several thousand dollars on mining hardware to make your mining operation profitable
Join a mining pool – This is the best option for success. One mining rig on its own will not be profitable.
Find a crypto wallet – You will need a place to store your mined coins. A cold wallet, one kept offline is the safest place for them.
