In a blockchain system, data is divided into multiple blocks, each containing a certain number of data records. When a new data record is added to the blockchain, the system ensures that all nodes reach consensus on the new data through distributed consensus algorithms.\n\nDistributed consensus algorithms mainly include Proof of Work (PoW) and Proof of Stake (PoS). Under the Proof of Work mechanism, nodes need  to prove their ownership of the block by solving a complex mathematical problem."}]}],"pr":"5f911ad6a79e32e53af52d5594663b1ec9922549c1d78d5ae996b6a99d4e63ff"}
