The block is the basic component of blockchain, which includes  a series of data records, a hash value of the previous block, a difficulty coefficient (regulating number), and a hash value of the current block. In the blockchain network, each block is generated with a certain computing power, which is usually measured based on the sha-256 algorithm. The time and computing power required to calculate a block depend on the hardware devices and computing power of the network."}]}],"pr":"e17985a54fc9577d27e008c502ad77a6a3db879f9872b0939134155bf1015f25"}
