Taking Bitcoin as an example, the reward calculation is based on the Proof of Work (PoW) consensus algorithm. In the Bitcoin network, miners compete to generate new blocks by solving complex mathematical problems, which require a large amount of computation to find the correct answers.  Whenever a miner successfully solves a block, they will receive a certain amount of Bitcoin as a reward. In addition, the Bitcoin network has a fixed reward halving period, which is every 210,000 blocks, meaning the reward received by miners will decrease over time."}]}],"pr":"1e79a46a47fa7b63eeaf1f99a06802f9e6288a998204ab0312c770258217c553"}
