A consensus mechanism adopted by the Bitcoin and Ethereum network where miners compete to solve complex math puzzles which require energy expended from computers to increase the odds of success.
The first computer to solve the puzzle earns the right to validate the next block of transactions and receive newly issued cryptocurrencies from the network, also known as the 'block reward' .
The current block reward for the Bitcoin network is 6.25 BTC per block and roughly 2.2 ETH per block for the Ethereum network.
