The activity of “mining” digital assets is the activity of processing transactions in a blockchain to get digital assets as a reward. In addition to getting a fee from each transaction processed, the miner will also get a Block Reward for each hash block that has been successfully processed. So, Block Reward is a number of digital assets obtained by miners who successfully process a block transaction. For bitcoin itself, the reward for each block in the first 210,000 blocks is 50 BTC. Every after 210,000 blocks (about 4 years), a Halving event will occur, in which the number of bitcoin rewards or the number of bitcoins that can be mined from each block, will be reduced by half.
