The consensus mechanism is a evaluation criterion in the blockchain system, which is used to determine which node has the right to record accounts and receive rewards. The blockchain system allocates rewards based on the performance of nodes in completing specific computational tasks, such as proof of work (POW) or proof of stake (POS). In the Bitcoin system, rewards mainly consist of two parts: one part is the coinbase transaction created by the node in the new block, which has no input UTXO and only output address. The node can set the output address to the private key address controlled by itself to receive the reward. The other part is the reward that the node can obtain from all transactions in the current block."}]}]}
