Different consensus mechanisms correspond to different voting rules, such as some requiring a majority of votes and others needing to reach two-thirds of the vote. In each blockchain network, all nodes have voting rights. When a new block needs to be generated, all nodes participate in the voting. According to the voting rules stipulated by the consensus mechanism, nodes vote to select those with the qualifications to create blocks.\n\nAfter a node obtains the right to generate a block, it will receive rewards from the blockchain, such as tokens (such as Bitcoin).  To receive rewards, nodes actively compete to generate blocks."}]}],"pr":"0eef3fa14fdf24f79e9b70d8d13eb7c988f0f3ccf426875c2e04157793a2f9e4"}
