  • Publication number: 20220311607
    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.

  • Publication number: 20220269568
    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.

  • Publication number: 20220269670
    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.

  • Publication number: 20220272038
    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.

  • Publication number: 20220247573
    Abstract: This application relates to a digital signature generation method and apparatus, a computer device, and a storage medium. The method includes: obtaining a message, and calculating a message hash value of the message; obtaining a signature private key, stitching the signature private key and the message hash value to obtain stitched information, calculating a hash value corresponding to the stitched information, and generating a digital signature corresponding to the message by using the hash value corresponding to the stitched information, the message hash value, and the signature private key. That is, generating a digital signature corresponding to a message by using a hash value corresponding to stitched information, a message hash value of the message, and a signature private key can improve security of the generated digital signature. This application can improve security in a blockchain consensus process.
