Problems solved by technology

[0004] In terms of cross-chain asset transfer, there are currently centralized exchanges that complete the conversion of assets on different chains, which is inconsistent with the decentralized nature of the blockchain, and it is also difficult to solve the transfer of non-asset information

Embodiment Construction

[0024] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred examples.

[0025] The cross-chain information verification method based on light node technology of the present invention has an operating framework as follows: figure 1 As shown, the information receiving chain (target chain) verifies the cross-chain information through the light nodes of the information source chain (source chain) before packaging a new block, so as to realize cross-chain information transfer. First, submit the block header information of the information source chain (source chain) to the information receiving chain (target chain) in a decentralized manner, and the information receiving chain (target chain) realizes the light node of the information source chain (source chain) by calling internally during the consensus process The information in the block header is verified in the same way, and the block heade...

Abstract

The invention discloses a cross-chain information verification method based on a light node technology, and the method comprises the following steps: S1, achieving a light node of an information source chain on an information receiving chain, wherein the light node synchronizes block head information through the connection with all nodes on the information source chain; S2, deploying a cross-chaininformation processing module on the information receiving chain; S3, realizing a decentralized relay; s4, verifying the block head from the information source chain through the light node, wherein the cross-chain information processing module receives the verified block head of the information source chain and then stores the verified block head; s5, verifying the received transaction certificate, transaction receipt certificate or state certificate after transaction execution according to the stored transaction root, transaction receipt root or state root in the block head, and extracting and subsequently processing the cross-chain information contained in the certificate after the verification is passed by the cross-chain information processing module.

Description

technical field [0001] The invention belongs to the technical field of blockchain, relates to blockchain light node technology and cross-chain technology, and specifically relates to a method for realizing cross-chain transactions by authenticating block headers and transaction information on the chain. Background technique [0002] Blockchain technology is a decentralized distributed database technology, which is characterized by decentralization, non-tampering and trustworthiness. At present, each chain is an independent closed system and cannot cooperate with other chains. [0003] The blockchain light node is a concept relative to the blockchain full node. The so-called full node is actually a node that synchronizes all blockchain data, including related information such as the block header (Block Header) and the blockchain body containing the transaction list. Because the full node saves the full amount of data, there is no need to rely on a third party when performin...
