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.

Abstract: Embodiments of this disclosure disclose a resource transfer data management method and apparatus, and a storage medium, which belong to the field of Internet technologies. The method includes: receiving transaction data transmitted by a first server, wherein the transaction data is obtained by the first server by signing resource transfer data according to a private key of the first server; verifying the transaction data according to a public key of the first server; and generating a second block according to the transaction data and a feature value of a first block in a blockchain when the verification succeeds, and adding the second block as a next block of the first block to the blockchain.

Abstract: Embodiments of this application provide a synchronization processing method, apparatus, and device, and a medium. The method includes obtaining a skeleton set and a synchronization task set, the skeleton set being used for storing M blocks to be synchronized by the first node device, the skeleton set comprising P skeletons, the synchronization task set comprising P synchronization tasks, the P skeletons being of a one-to-one correspondence to the P synchronization tasks, and M and P both being positive integers; selecting a second node device from the candidate node set, the second node device being a candidate node device in the candidate node set; concurrently transmitting synchronization tasks in the synchronization task set to the second node device, the second node device performing the synchronization tasks and returning the M blocks; and filling the M blocks into the skeletons in the skeleton set.

Abstract: Aspects of the disclosure provide a method for displaying blockchain data, a blockchain browser, a user node, and a medium. The method can include transmitting a blockchain data query request, and receiving blockchain data obtained through query in response to the blockchain data query request. Further, the method can include obtaining filtered blockchain data, the filtered blockchain data being generated after illegal content in the blockchain data is filtered out based on a filtering rule, and displaying the filtered blockchain data. In embodiments of this disclosure, the display of the illegal content in the blockchain data can be automatically skipped.

Abstract: A blockchain-based data snapshot method, performed by a consensus node in a blockchain network, includes: obtaining a snapshot trigger instruction and a trigger moment of the snapshot trigger instruction; performing snapshot processing on one or more transaction blocks in a ledger at the trigger moment, to obtain a snapshot account state of a transaction account, the snapshot account state being account data related to transaction data in the transaction blocks; obtaining a write-ahead logging (WAL) log of a target block, the target block being a block with a highest block height in the transaction blocks, the WAL log including a log of account data corresponding to the target block; and correcting dirty data in the snapshot account state according to the WAL log, to obtain a corrected snapshot account state, the dirty data being generated based on incomplete transaction data in the target block included in the ledger.
