Blockchain nodes compete to solve a cryptographic puzzle related to the previous block's consensus hash, and the node that solves it first gets the right to add the next block. The consensus hash ensures the security and  consistency of the blockchain."}]}],"pr":"7a1ccb51a0b09d883eefc8045ef46402bd5870e9aa964fffa44bff782a9af11c"}
