Mining
Mining
The process of performing computations to add new blocks to a blockchain and earn rewards in return.
In Simple Terms
Mining is the process of performing massive amounts of computation to add new blocks to a blockchain. Participants race to be the first to find a specific calculation result (a hash value) that meets certain conditions, and whoever gets there first is rewarded with newly created cryptocurrency. It's an essential mechanism for maintaining the security and reliability of networks like Bitcoin.
Behind the Name
"Mining" gets its name from the traditional practice of digging for valuable minerals like gold and diamonds using pickaxes and shovels. The term carries over here because the process feels similar: computers perform enormous amounts of calculation to add new blocks to the blockchain, effectively unearthing new coins as a reward.
Take a Closer Look!
Mining is the computational work used to add new blocks to a blockchain in cryptocurrencies that rely on a system called Proof of Work (PoW), such as Bitcoin.
In networks like Bitcoin, there's no central authority like a bank managing transactions, so computers belonging to participants around the world (called nodes) each independently check whether incoming transactions and blocks follow the rules.
Mining is the process that decides who earns the right to create the next block. In practice, it involves using computers to solve what amounts to an extremely complex mathematical puzzle.
Whoever solves this puzzle first, anywhere in the world, wins the right to add the block and receives newly created cryptocurrency as a reward.
Some cryptocurrencies that also operate without a central authority use a different system called Proof of Stake (PoS) instead.
PoS selects who creates the next block through a process called "staking," where participants lock up their own cryptocurrency. Since it doesn't involve a computational race like mining, this process isn't called mining.
Mining requires extremely fast, high-performance computers, along with huge amounts of electricity to keep them running.
As a result, massive facilities packed with rows of specialized machines have been built around the world, giving mining a major impact on IT infrastructure and hardware as well.
