Abstract: Embodiments of the present disclosure relate to a cooling device, including a housing and a heat dissipation assembly. A sealed space for accommodating cooling liquid is formed in the housing. The cooling liquid is in contact with a to-be-cooled component. The heat dissipation assembly includes a heat dissipation assembly body and a heat conducting pipe communicating with the heat dissipation assembly body. The heat dissipation assembly body is arranged in the sealed space formed by the housing. The heat dissipation assembly body is configured to, after the cooling liquid transforms into the gas by absorbing the heat of the to-be-cooled component, absorb the heat of the gas to convert the gas into the liquid. The heat conducting pipe is at least partially located outside the housing. The heat dissipation assembly body is arranged at ½ to ¾ the position along the height direction in the housing.

Abstract: A monitoring method includes obtaining identification information of a digital certificate processing device, establishing a connection with the digital certificate processing device according to the identification information, sending monitoring information to the digital certificate processing device, receiving operation data fed back according to the monitoring information, and monitoring an operation status of the digital certificate processing device according to the operation data.

Abstract: The present disclosure provides a currency settlement method and apparatus. The currency settlement method includes: settling with a mining node that acquired a first virtual currency according to a workload performed by the mining node and an income type of the mining node; according to a settlement currency type, transacting with an exchange institution to exchange an amount in the first virtual currency into an amount in a second virtual currency, the second virtual currency being the settlement currency type; and transferring the amount of the second virtual currency to an account.

Abstract: The present application relates to a method and an apparatus for simulating digital certificate generation, a method, a module, and a system for diagnosing a mining pool, a storage medium, and a program product. The method for simulating digital certificate generation includes: determining a digital certificate connection protocol based on a digital certificate type; simulating, based on the digital certificate connection protocol, establishing, by a digital certificate generation device, a connection to a mining pool; simulating sending, by the digital certificate generation device, digital certificate generation request information to the mining pool; and receiving feedback information of the mining pool for the digital certificate generation request information.

Abstract: The present application relates to a digital certificate processing method and system, a gateway, a device, a medium, and a program product. The digital certificate processing method is a distributed digital certificate processing method, which is applied to a gateway. The distributed digital certificate processing method includes: polling a digital certificate processing node to obtain latest digital certificate processing task template data; generating simplified task template data of a digital certificate processing task based on the digital certificate processing task template data; and distributing the simplified task template data to a digital certificate processing service device.
