Block chain key generation method and device, equipment, medium and product

The invention provides a key generation method and device of a block chain, equipment, a medium and a product, and relates to the field of block chains. The method comprises the steps of obtaining current running information of hardware, performing coding processing on the running information to obtain a first random number, generating a second random number by calling a quantum random number generator, generating a target random number sequence according to the first random number and the second random number, and sending the target random number sequence to the hardware. Performing calculation processing on the target random number sequence based on an elliptic curve algorithm to obtain a master key pair, and performing calculation processing on a master private key in the master key pair by using a key derivation algorithm to obtain a plurality of sub-key pairs; according to the method provided by the invention, the problem that the resource demand is too high when the quantum computer is used for generati
