Abstract

The embodiment of the invention provides a crowd sensing method and system based on blockchain, and the method comprises the steps: selecting a worker when a task requester issues a task to the blockchain, and selecting a verifier through executing a verifier selection intelligent contract; after the worker completes the task, when perception data is submitted to a task requester through a blockchain, executing a worker employment smart contract, enabling a verifier to verify an employment relationship between the worker and the task requester, and completing the first consensus; after the task requester performs data quality evaluation on the perception data, submitting an evaluation result and the perception data to the blockchain, executing a data verification intelligent contract, andenabling the verifier to verify the perception data according to the perception data submitted by the task requester and the perception data submitted by a worker during first consensus; determining whether payment operation is executed or not according to the evaluation result, and completing second consensus; if the payment operation can be executed, paying a corresponding reward to the worker.According to the method and the system, the workload of the participation nodes can be reduced.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a blockchain-based crowd sensing method and system. Background technique [0002] With the development of mobile communication, Internet of Things technology and the development of functional diversity of mobile devices, crowd sensing system, as a new and effective data collection technology, has been applied in monitoring environment, public infrastructure, social network and other fields. [0003] In order to achieve efficient collection of sensing data in different scenarios and ensure system security, existing crowd sensing systems generally adopt a proof of work mechanism (Proof Of Work) in the consensus stage. , POW), and, in order to protect privacy, a very complex encryption algorithm (for example, homomorphic encryption algorithm, secure multi-party computing, etc.) is used, which greatly increases the workload of participating nodes ...
