Abstract: A data processing method includes: transmitting, by a first service node, service data information to a second service node, so that the second service node obtains data signature information; a first key parameter and a second key parameter that are both related to a random parameter; the random parameter being determined by the second service node based on a node private key and the service data information; performing signature verification on the received data signature information based on the first key parameter and the second key parameter, and adding a signature verification result obtained after signature verification to a verification result set; searching for a target signature verification result that satisfies a valid verification condition from the verification result set; and performing aggregate signature on the data signature information obtained after calculation when a quantity of signatures of the target signature verification result satisfies an aggregate signature condition.

Abstract: A data processing method for blockchain technology verifies transactions. Transaction operations on a blockchain are more consistent and the accuracy of transaction data on the blockchain is improved. A first transaction operation corresponding to a first transaction request on the blockchain, and a second transaction operation corresponding to a second transaction request on the blockchain are both performed. When an operation result corresponding to either the first transaction operation and/or the second transaction operation is a failure, then the processing on a transaction operation can be rolled back to a successful operation.

Abstract: This application discloses an information filtering method and an information processing apparatus. Shared information that is shared by a user account of an online service is obtained. A credibility reference rating associated with the user account is obtained. The credibility reference rating indicates account credibility of the user account. Whether the shared information satisfies a filtering condition is determined based on the credibility reference rating. Further, the shared information is filtered when the shared information is determined to satisfy the filtering condition.

Abstract: This application discloses a key generation method and apparatus, a device, and a medium. The method includes transmitting a key negotiation request to a consensus node in a blockchain network, to request a key verification parameter; negotiating a collaboration key pair with a second device to obtain a first private key component and a shared public key in the collaboration key pair; signing the key verification parameter by using the first private key component, to obtain a first signature component; generating transaction data according to the first signature component and the key verification parameter; transmitting the transaction data to the second device. The consensus node performs a consensus on the negotiation result data, and after the negotiation result data passes the consensus, submits the negotiation result data to a blockchain of the blockchain network.

Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.
