Title:
CROSS-CHAIN BLOCKCHAIN COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/105565
Kind Code:
A1
Abstract:
Provided in the embodiments of the present invention are a cross-chain blockchain communication method and apparatus. The method comprises: a cross-chain verification node receiving first cross-chain ciphertext sent by a first proxy node; decrypting the first cross-chain ciphertext to obtain a second cross-chain request, and verifying the second cross-chain request; and after the second cross-chain request passes verification, triggering a blockchain system, where a second proxy node is located, to process the second cross-chain request. A proxy node is used for forwarding, transmitting and receiving cross-chain messages of nodes in a blockchain system, first cross-chain ciphertext is generated after a first proxy node achieves a consensus on a first cross-chain request that is initiated by a local chain node, and after a second cross-chain request passes verification, a blockchain system where a second proxy node is located is triggered to process the second cross-chain request, and therefore, the security of cross-chain communication can be ensured. In addition, in the technical solution, there is no need to manage and maintain the generation, issuance, revocation, etc. of a large number of user certificates, and therefore, computing resources and storage resources can be saved.
