A storage medium storing an information management program that causes a computer to execute a process that includes acquiring a first cumulative consideration amount from a most upstream process in a plurality of processes included in a supply chain to a first process; generating a consideration amount commitment by concealing the first cumulative consideration amount by using a random number; registering the consideration amount commitment in a blockchain; generating a consideration amount proof that is a zero knowledge proof that proves validity of the second cumulative consideration amount without disclosing the second cumulative consideration amount; and notifying the second process of the second cumulative consideration amount, the random number, and the consideration amount proof.

Storage medium, consideration distribution method, and information management device

Disclosed are a method and apparatus for processing information by cooperation of multiple subjects, by submitting an information processing task to first multiple subjects; performing security analysis on information processing results obtained by executing the information processing task by the first multiple subjects, determining an updated processing manner of executing the information processing task based on a result of the security analysis; and submitting the information processing task to second multiple subjects according to the determined updated processing manner. Information processing results of executing the information processing task by the second multiple subjects are obtained, each of the second multiple subjects and each of the first multiple subjects save same information associated with the information processing task, and the information is updated based on the information processing results of executing the information processing task by the second multiple subjects.

Method and apparatus for processing information by cooperation of multiple subjects

A device for testing a blockchain network is provided. The device includes a processor. The processor is configured to calculate a matching degree between a configuration of the blockchain network and a template configuration corresponding to application scenario of the blockchain network; calculate performance of the blockchain network; calculate a health degree for the blockchain network; and determine whether the blockchain network is in a stable state based on the matching degree, the performance and the health degree.

Device for testing blockchain network

Disclosed are a method and apparatus for managing effectiveness of an information processing task in a decentralized data management system. The method comprising: sending requests for multiple information processing tasks by a client to multiple execution subjects, transmitting information processing tasks in a sequential information processing task list in an order to the multiple execution subjects; caching the requested information processing tasks to a task cache queue, caching the sequential information processing task list as a whole to the task cache queue; judging whether each information processing task in the task cache queue satisfies a predetermined conflict condition; moving the information processing task to a conflict task queue if it is determined that the task satisfies the predetermined conflict condition, deleting the task from the conflict task queue and caching the task to the task cache queue when the predetermined conflict condition is not satisfied.
