    摘要: The present disclosure is directed to a block processing method, apparatus, and non-transitory computer medium. The method includes obtaining a time interval stored in a root block of a target blockchain based on generation of a block. The method further includes determining a subchain as a target subchain, the subchain meeting a target condition from a first target quantity of subchains connected to the root block when a transaction occurrence time of a transaction included in the block being within the time interval. The method also includes adding the block to the target subchain of the target blockchain when a consensus is reached on the block.

    摘要: This application relates to a third-party settlement control method performed by a third-party settlement node that is communicatively connected to multiple transaction participant nodes. The method includes: responding, by the third-party settlement node, to a settlement request, and transmitting the settlement request to the transaction participant nodes associated with the settlement request; receiving, by the third-party settlement node, acceptance opinions transmitted by the transaction participant nodes, the acceptance opinion being used for indicating a processing result of the settlement request by each of the transaction participant nodes; and determining, by the third-party settlement node, transaction consensus information according to the received acceptance opinions, and performing a third-party settlement according to the transaction consensus information, the transaction consensus information being used for indicating whether the transaction participant nodes reach a complete consensus on the settlement request.

    摘要: A credit scoring method and a server are provided. The method includes: determining at least one target user set in a plurality of user sets. The at least one target user set includes first behavior-unknown users whose predicted profit values are higher than second behavior-unknown users, the second behavior-unknown users are users other than the first behavior-unknown users on an application platform. The method also includes determining credit scores of first behavior-unknown users according to credit scores of behavior-known users in at least one determined target user set; obtaining first user samples from the first behavior-unknown users according to credit records of the first behavior-unknown users, the first user samples having profit values that satisfy a preset threshold; and performing credit scoring for a user according to a second scoring model obtained through training a first scoring model according to the first user samples and second user samples.

    摘要: A method includes obtaining first traveling information of a vehicle from a sensor associated with the vehicle, and determining, based on the first traveling information, first location information of the vehicle and a first intermediate variable that is used in the determining the first location information. The method also includes determining a target precision estimation model from a plurality of pre-trained precision estimation models based on the first traveling information and the first intermediate variable. The plurality of pre-trained precision estimation models are obtained by training a machine learning model based on a training sample set. The method also includes inputting the first location information and the first intermediate variable into the target precision estimation model to obtain second location information of the vehicle and a precision error of the first location information relative to the second location information.

    摘要: A blockchain-based content processing method is provided. The method includes: obtaining, by a content server, fingerprint information of content data being published; transmitting, by the content server, the fingerprint information of the content data to a blockchain system; and storing, by the content server by using the fingerprint information of the content data as an index, the content data into a target file system in response to receiving a storage success message returned by the blockchain system.
