What Is Bitcoin Mining?

One of the elemental questions many of us have about Bitcoin revolves round the tokens themselves. questions on its value, security and history, all eventually cause one place: Where do bitcoins come from?

While traditional money is made through (central) banks, bitcoins are “mined” by Bitcoin miners: network participants that perform extra tasks. Specifically, they chronologically order transactions by including them within the Bitcoin blocks they find. This prevents a user from spending an equivalent bitcoin twice; it solves the “double spend” problem.

Skipping over the technical details, finding a block most closely resembles a kind of network lottery. for every plan to attempt to find a replacement block, which is essentially a random guess for a lucky number, a miner has got to spend a small amount of energy. Most of the attempts fail and a miner will have wasted that energy. just one occasion about every ten minutes will a miner somewhere succeed and thus add a replacement block to the blockchain.

This also means any time a miner finds a legitimate block, it must have statistically burned far more energy for all the failed attempts. This “proof of work” is at the guts of Bitcoin’s success.

For one, proof of labor prevents miners from creating bitcoins out of thin air: they need to burn real energy to earn them. And two, proof of labor ossifies Bitcoin’s history. If an attacker were to undertake and alter a transaction that happened within the past, that attacker would need to redo all of the work that has been done since to catch up and establish the longest chain. this is often practically impossible and is why miners are said to “secure” the Bitcoin network.

In exchange for securing the network, and because the “lottery price” that is an incentive for burning this energy, each new block includes a special transaction. It’s this transaction that awards the miner with new bitcoins, which is how bitcoins first inherit circulation. At Bitcoin’s launch, each new block awarded the miner with 50 bitcoins, and this amount halves every four years: Currently each block includes 12.5 new bitcoins. Additionally, miners get to stay any mining fees that were attached to the transactions they included in their blocks.

Anyone can become a Bitcoin miner to undertake and earn these coins. However, Bitcoin mining has become increasingly specialized over the years and is nowadays mostly done by dedicated professionals with specialized hardware, cheap electricity and sometimes big data centers.

To mine competitively today, you would like to understand what you’re doing, you want to be willing to take a position significant resources and time, and — last but not least — you would like access to cheap electricity. If you've got all of this, you can also provides it an attempt and become a Bitcoin miner.
