Abstract: A method for translating subtitles, an electronic device, and a non-transitory storage medium in the present disclosure acquire subtitle information. When there are the currency amount information in the subtitle information, a preset target currency category and a preset target language category are obtained, currency amount information in the subtitle information is converted into target currency amount information corresponding to the target currency category, and text information in the subtitle information is converted into target text information corresponding to the target language category. Updated subtitle information is obtained according to the target currency amount information and the target text information and the updated subtitle information is displayed.

Abstract: A consumer comments storage method and an electronic device are disclosed. In response to a user requesting to make a comment on a target commodity, the method acquires an authorization certificate from a payment platform and obtains a first commodity purchase record of the user according to the authorization certificate. When the target commodity is recorded in the first commodity purchase record, it is determined that the user has a right to comment on the target commodity. A command on the target commodity entered by the user is received and the comment and the authorization certificate are uploaded to a blockchain to enable a smart contract of the blockchain to verify the comment. A verification result returned by the blockchain is received and when the returned result is a verification successful result, the comment is retained. The storing of comments in the blockchain ensures the authenticity of the comments.

Abstract: A method applied to a mining machine for limiting computing power includes utilizing a dictionary library and a timestamp to control Nonce combination that can be tried per unit time. If all strings in the dictionary library have been tried, as long as a time difference between time of generating most recent timestamp and the current time is less than a preset threshold, the mining machine must wait in sleep state and cannot resume mining until the time difference exceeds the preset threshold. The present disclosure can avoid a situation that the calculation power of the mining machine is too strong and causes a monopoly of the calculation power.

Abstract: A method of verifying identity for a computerized account, a computing device, and a storage medium are disclosed, the method obtains a username and searches for a verification address corresponding to the username according to a comparison table that records relationships between usernames and verification addresses. The verification address is stored on a blockchain network node, transaction information sent from an account address to the verification address is monitored through the verification address, and the account address is stored on the blockchain network node. If the transaction information sent to the verification address from an account address that matches the username, a prompt indicating that the username is successfully authenticated is sent to a user terminal corresponding to the username. The method enables identity verification in an efficient and a safe manner.

Abstract: A blockchain transaction privacy protection method includes receiving a transaction request sent by a receiving node device, the request including a plurality of receiving accounts and a total amount receivable, and sending a plurality of transaction sequence numbers and a virtual wallet address corresponding to each of the plurality of transaction sequence numbers to the receiving node device, thereby making the receiving node device send a total amount receivable, the plurality of transaction sequence numbers, and the virtual wallet address corresponding to the plurality of transaction sequence numbers to a granting node device. A total amount receivable and the plurality of transaction sequence numbers sent by the granting node device are received. A transaction amount to each receiving account of the receiving node device according to the total amount receivable and the plurality of transaction sequence numbers are transferred, protecting the amount of the transaction and the parties.
