The invention provides a block chain-based information processing method and device, equipment, a medium and a product, and can be applied to the block chain field and the financial field. The information processing method is executed by any first node in a first block chain network, the any first node is associated with at least one second node in a second block chain network, and the information processing method comprises the following steps: obtaining transaction information sent by the associated second node; encrypting the transaction information by adopting a first predetermined encryption algorithm to obtain first encrypted information; sending the first encrypted information to an associated first node, so that the second block chain network performs consensus verification on a transaction indicated by the transaction information based on the first encrypted information; using a second predetermined encryption algorithm to generate an anonymous transaction verification message for the transaction information; and broadcasting an anonymous transaction verification message to other first nodes except any first node in the first block chain network to perform transaction verification on the transaction indicated by the transaction information.
Description
technical field [0001] The present disclosure relates to the field of computer technology, specifically to the field of block chain and financial field, and more specifically to a block chain-based information processing method, device, equipment, medium and product. Background technique [0002] Blockchain technology is a distributed Internet database technology. It has many inherent advantages, such as decentralization, detrust, non-tampering, autonomy, etc., which can enable unfamiliar nodes to communicate without relying on third-party trusted institutions. The main advantage of establishing a point-to-point credible value transfer under the circumstances is that it can significantly reduce the cost of trust and improve interaction efficiency. The blockchain does not depend on a specific central node. Each blockchain node in the system stores and processes data independently, effectively avoiding single point failure. [0003] In order to achieve public verification, th...
