Abstract: The invention disclose a blockchain-based mining method, mining device, computer equipment and storage medium. The method comprises: acquiring block header information of a to-be-generated block published by a mining pool; generating a random term based on a public key of the mining pool, a public key of the miner, POW of the miner and physical interaction information broadcast by other miners in the mining pool; calculating a to-be-verified hash value based on the block header information and the random term; if the to-be-verified hash value satisfies block generation condition, transmitting the to-be-verified hash value to the mining pool, so the mining pool generates the to-be-generated block after the to-be-verified hash value passes verification. In this invention, utilizing physical interaction information among miners to generate the random terms, so the original random terms which need to be generated at high-speed randomly are replaced, avoiding wasting computing power and electric power.

Abstract: The invention provide an assessment method and device for infectious disease transmission, computer equipment and storage medium. The method comprises: obtaining respective target track data corresponding to assessment objects within a preset area in a first time slice; determining a matching subarea to which each assessment object matches in the first time slice based on the target track data; taking at least one of the plurality of subareas as a target subarea, and assessing an assessment object within the target subarea based on an infectious disease model to determine a transmission trend of an infectious disease for the assessment object within the preset area in the first time slice; and taking a next time slice as the first time slice, and re-performing the above steps until end of the target time period to determine a transmission trend of the infectious disease among the assessment objects during the target time period.
