Patent number: 11973858Abstract: 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.Type: GrantFiled: March 12, 2021Date of Patent: April 30, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Maocai Li, Hu Lan, Zongyou Wang, Kaiban Zhou, Haitao Tu, Jinsong Zhang, Yifang Shi, Changqing Yang, Li Kong, Gengliang Zhu, Yong Ding, Qucheng Liu, Qiuping Chen, Peng Wang

Patent number: 11968294Abstract: 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.Type: GrantFiled: January 13, 2021Date of Patent: April 23, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Maocai Li, Zongyou Wang, Li Kong, Kaiban Zhou, Hu Lan, Yifang Shi, Changqing Yang, Jinsong Zhang, Yong Ding, Gengliang Zhu, Qucheng Liu, Qiuping Chen

Patent number: 11966916Abstract: A second blockchain system receives a first consensus message from a first blockchain system, the first blockchain system includes first nodes that provide services to at least a first account, and the second blockchain system includes second nodes that provide services to at least a second account. The first consensus message indicates a first plurality of the first nodes reaches a consensus for transferring a resource from the first account to the second account. The second blockchain system transfers the resource in the task to the second account. The transferring includes that a node in the second nodes adds the resource to the second account and generates a fourth block that records a completion of a transfer event. A second consensus message is transmitted from the second blockchain system to the first blockchain system in response to a second plurality of the second nodes completing the transfer event.Type: GrantFiled: February 24, 2023Date of Patent: April 23, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Rui Guo, Maocai Li, Jun Liang, Jianjun Zhang, Zongyou Wang, Haitao Tu, Qi Zhao, Binhua Liu, Dawei Zhu, Qing Qin

Patent number: 11936769Abstract: Aspects of the disclosure provide methods and apparatuses for storing data. In some examples, an information processing apparatus that includes processing circuitry is provided. The processing circuitry is configured to receive data and determine a target blockchain based on an attribute associated with the data and blockchain correspondence information. The blockchain correspondence information indicates attributes associated with a plurality of blockchains. Further, the processing circuitry is configured to store a first block that is generated based on the received data in the target blockchain.Type: GrantFiled: February 17, 2021Date of Patent: March 19, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Rui Guo, Maocai Li, Jun Liang, Jianjun Zhang, Zongyou Wang, Qi Zhao, Haitao Tu, Binhua Liu, Dawei Zhu, Qing Qin

Publication number: 20240073045Abstract: A blockchain-based data processing method, apparatus, and computer-readable medium are provided. Block proposal information is received including a block and a digital signature transmitted by an out-block node. The digital signature is obtained by performing digital signature processing on block header information included in the block. The block header information includes a first Merkel root determined based on transaction data in the block body information. Digest calculation on the block header information is performed to obtain first digest information. De-signature processing is performed on the digital signature to obtain second digest information. A second Merkel root is determined based on the transaction data acquired from the block proposal information when the first digest information and the second digest information are matched. An operation on the block is performed based on a comparison result of the first Merkel root and the second Merkel root.Type: ApplicationFiled: November 7, 2023Publication date: February 29, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Qucheng LIU, Zongyou WANG, Jinsong ZHANG, Gengliang ZHU, Yifang SHI, Hanqing LIU, Yingjie GUO, Zhiyong LIAO, Hu LAN
