On any blockchain, the hash rate is the speed at which a miner arrives and finds a hash. Once the hash is found, the block is closed, and the miner/pool of miners are rewarded with newly-created Bitcoin and transaction fees. To get this number, a computer has to try multiple times.

On the Bitcoin network, miners have to find a hash that starts with approximately seventeen zeroes. When the computational problem is solved by the mining card, the product is a seemingly-random 64 character output called a hash. Since then, individuals from around the world have sought the best GPUs to get their share of crypto block rewards.Д®ncrypted in the SHA-256 problems solved by computers are details of electronic payments and algorithms necessary to secure a blockchain network from attackers wishing to ' double-spend.' For partaking in the security of the blockchain network, miners are rewarded with crypto coins. GPU mining became a hot topic in 2017 after Bitcoin zapped past its previous highs to peak at just under $20,000 (a little less than half of what it would later reach in January 2021!). In this way, individual computers represent workers in a mine getting paid for searching for the treasure, the block reward. Rewards are handed out to miners after a block of the currency has been mined.ДЄll the participants in a shared pool get a share in the profits based on how much computing power they contributed. Most mining operations, including the use of graphics cards and specialized mining rigs, are now conducted in shared pools, where participants combine their computing powers into a big group to generate results more quickly.

While it used to be possible mine Bitcoin and other cryptocurrencies at home with your laptop, that's no longer an option for most cryptos due to the rising interest in mining, along with the Bitcoin reward halvings.
