  • Publication number: 20210286900
    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.

  • Publication number: 20210203482
    Abstract: Aspects of the disclosure are directed to a method for use on a blockchain network that includes an accounting node subnetwork having accounting nodes configured to record a data block onto a blockchain and a service node having service nodes configured to verify data blocks recorded by the accounting nodes onto the blockchain. The method can include generating a signature based on transaction information to be included in a data block to be added onto the blockchain by using a key specific to the accounting node. The method can further include adding the transaction information and the generated signature to the data block and adding the data block onto the blockchain, and transmitting the signature to the service nodes in the service node subnetwork, so that the service nodes perform signature verification on the signature based on the key specific to the accounting node.

  • Publication number: 20210135848
    Abstract: This application provide a data management method for a blockchain system, a medium, and an electronic device. The system includes an accounting node sub-network and a service node sub-network. The method includes: adding, after an accounting node generates a first data block, first key information used for verifying a block header of a second data block generated after the first data block to a block header of the first data block; generating a signature corresponding to the first data block, and adding the signature corresponding to the first data block to the block header of the first data block; and releasing the block header of the first data block to the service node sub-network, to cause a service node to verify the signature included in the block header of the first data block, and obtaining the first key information after a successful verification to verify the block header of the second data block.

  • Publication number: 20210049596
    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.

  • Publication number: 20210027310
    Abstract: A method for electing a representative node device performed by a first node device in a blockchain system includes: broadcasting candidate addition transaction data in the blockchain system, the candidate addition transaction data carrying credential data, the credential data being received from a target server and indicating that a first node device meets a qualification requirement for a candidate node device; storing the candidate addition transaction data on a target blockchain of a blockchain system when a plurality of node devices in the blockchain system verify the candidate addition transaction data by consensus; and participating in an election of the representative node device according to the candidate addition transaction data stored on the target blockchain.

  • Publication number: 20210027289
    Abstract: In a transaction method, transaction information is obtained. The transaction information includes a type identifier and quantity of first assets, and a type identifier and quantity of second assets. Transaction records, corresponding to a transaction in a block, are stored upon verification of the transaction information. The transaction records include first and second transaction records. The first transaction record includes first input and output items corresponding to the first assets, and the first input and output items each includes the type identifier of the first assets. The second transaction record includes second input and output items corresponding to the second assets, and the second input and output items each includes the type identifier of the second assets. The block is broadcasted to other nodes in the blockchain network, and verification results are received. The block is added to a blockchain of a current node based on the verification results.

  • Publication number: 20210021412
    Abstract: A method for electing a representative node device for a blockchain system includes: receiving IP address information of a first node device, the first node device being in a candidate state for a representative node device; receiving, from the first node device, an IP address obtaining request for requesting IP address information of a representative node device; when the first node device is determined to be a representative node device of the blockchain system elected in a current election process, transmitting, to the first node device, an IP address list comprising IP address information of representative node devices elected in the current election process; and when the first node device is determined not to be a representative node device of the blockchain system elected in the current election process, skipping the IP address obtaining request.
