Publication number: 20240160755Abstract: A processing method includes acquiring, by a first service node of a first blockchain, a cross-chain transfer request, the cross-chain transfer request including a virtual resource value, a first resource transfer-out address on the first blockchain, and a first resource transfer-in address on a second blockchain. The cross-chain transfer request is used by a second service node of the second blockchain to lock a first virtual resource of the virtual resource value in the second blockchain. The method further includes performing resource transfer-out processing on a second virtual resource associated with the virtual resource value in the first resource transfer-out address in response to a determination that the second service node locked the first virtual resource successfully. The method further includes transferring the first virtual resource to the first resource transfer-in address in the second blockchain in response to a determination that the second virtual resource was transferred out.Type: ApplicationFiled: December 4, 2023Publication date: May 16, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Yifang SHI, Zongyou WANG, Qucheng LIU, Gengliang ZHU, Hanqing LIU, Zhiyong LIAO, Yangjun HUANG, Kaixuan NIE

Publication number: 20240104558Abstract: In a blockchain transaction execution method, a first transaction of a first blockchain is received from a proxy program component. The first transaction is based on a second transaction of a second blockchain. A data structure of the first transaction is different from a data structure of the second transaction. The second transaction is extracted from the first transaction. A virtual machine is invoked to execute the second transaction of the second blockchain. An execution result of the second transaction is transmitted to the application via the proxy program component.Type: ApplicationFiled: October 12, 2023Publication date: March 28, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Rui GUO, Zongyou WANG, Yifang SHI, Zhiyong LIAO, Gengliang ZHU, Qucheng LIU, Hanqing LIU, Hu LAN

Publication number: 20240097898Abstract: In a blockchain data processing method, service updating data of each of a plurality of encrypted data is received. The service updating data of each of the plurality of encrypted data includes encrypted primary key information of the respective encrypted data. Each of the plurality of encrypted data includes service data encrypted by a respective service node of a plurality of service nodes. Service intersection data is generated based on a data intersection of the service updating data of the plurality of encrypted data. The service intersection data is transmitted to a service node of the plurality of service nodes. The service intersection data includes supplemental text data from another service node of the plurality of service nodes.Type: ApplicationFiled: December 2, 2023Publication date: March 21, 2024Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Hanqing LIU, Zongyou WANG, Hu LAN, Yifang SHI, Gengliang ZHU, Qucheng LIU, Zhiyong LIAO

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

Patent number: 8668478Abstract: A scroll compressor includes a discharge valve assembly having a valve member, a valve stop supported within the compressor shell and including an aperture there through and a communication member. The communication member defines a fluid passage extending into the discharge chamber from the valve stop toward the first discharge outlet in the discharge chamber and provides fluid communication between the aperture in the valve stop and a location downstream of the valve stop. A first side of the valve member abuts the valve stop when in an open position and the valve stop provides communication between the first side of the valve member and the communication member via the aperture.Type: GrantFiled: June 7, 2011Date of Patent: March 11, 2014Assignee: Emerson Climate Technologies, Inc.Inventors: Xiaogeng Su, Weihua Guo, Hanqing Zhu, Xiaomin Qu
