Surely many wondered why cryptocurrency farms consume a lot of electricity?The process itself is called proof of work. That is, when you send a crypto currency to another recipient, he in turn must make sure that it does not belong to You anymore, and this proof is the large number of computers (miners) generated and recorded in the form of "blocks" in the network. Each block includes information about the previous one, which makes it impossible to change all the blocks in this chain, hence the name of the blockchain.This whole process is quite energy-intensive, and explains why it is so expensive to store large amounts of data in the blockchain network.
