Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for product promotion using a smart contract in a blockchain network. The method includes: receiving, by a node of a blockchain network, a creation request to create a promotion event, wherein: the promotion event is associated with multiple promotion codes and a pair of a private key and a public key, and the creation request includes the public key and a digital signature generated using the private key; determining, by the node and based on the public key and the digital signature, validity of the creation request; and in response to determining that the creation request is valid, registering, by the node, the promotion event in the blockchain network using a smart contract without storing the multiple promotion codes in the blockchain network.
