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: 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
