All separate records should match to confirm the validity of a transaction. This is similar to how blockchain works. It is composed of thousands or even millions of record-keeping machines. And these machines will compare results with each other. This system requires a huge amount of computing power to operate. So they outsource the computer power to the public. The public can participate in the blockchain by lending the computing power of their devices and in return will get a reward. Lending your computer power to a blockchain used in cryptocurrency is now called “Crypto Mining”.Continue reading next article -->
