Block rewards are new bitcoins granted to cryptocurrency miners for solving a challenging mathematical problem and establishing a new block of validated bitcoin transactions. Miners accomplish this using computer networks, and each time a new block is generated, it is validated by all other competing miners. Then, a fresh mathematical issue is presented, and the miners begin again.
The block reward granted to miners for processing transactions is halved once blocks have been mined. This is known as halving, because it halves the rate at which new coins are introduced into circulation.
The quantity of the prize is subject to change based on a predetermined formula. Traditional mining and stacking strategy makes extensive use of the function in the blockchain that divides the reward in half after every certain number of blocks that have been mined.
