Cross-Blockchain Resource Transmission via Relay End
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain technologies are limited in cross-chain applications as they do not coordinate or cooperate with other chains for value circulation, restricting their potential across various fields.
Innovation Solution
A method and apparatus for cross-chain resource transmission using an authenticable message with a predetermined protocol stack, allowing a blockchain to send and receive resources across different chains through a relay end, which includes decrementing resource balances and incrementing them based on conversion ratios, and utilizing smart contracts for transaction execution and verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cross-chain platforms are used for resource transmission between different chains, then cross-chain resource circulation is enabled, but device complexity increases
Solution Approach 1:
The patent creates a universal cross-chain message transmission mechanism that can handle resource transmission between any two blockchains. The authenticable message format and relay end design enable a single platform to serve multiple cross-chain communication needs, replacing the need for multiple specialized cross-chain platforms. The message structure with standardized fields (sender, receiver, resource type, amount) allows one platform to universally manage diverse cross-chain resource transmissions.
2Adaptability or versatility
If cross-chain resource transmission is implemented without standardized protocols, then flexibility is maintained, but measurement precision decreases
Solution Approach 1:
The patent establishes standardized parameter structures for cross-chain messages, including fixed fields for sender identity, receiver identity, resource type, and transmission amount. This parameter standardization ensures precise authentication and processing of cross-chain messages while maintaining adaptability through the extensible message format that can accommodate different resource types and blockchain protocols.
3Adaptability or versatility
If resource conversion ratios are calculated dynamically, then adaptability to market conditions is improved, but loss of time increases
Solution Approach 1:
The patent implements a mechanism where resource conversion ratios are predetermined and embedded in the authenticable message structure during message creation. This preliminary determination of conversion ratios eliminates the need for real-time calculation during message processing, reducing time loss while maintaining the ability to adapt to market conditions through updated ratio values in subsequent transmissions.

AI summary
Examples of a method and apparatus for cross-chain resource transmission are described. The cross-chain resource transmission includes sending from a first account of a first blockchain to another blockchain. One example of the method is executed by the first blockchain and includes: initiating, by the first account, a first transaction used for cross-chain resource transmission, to decrement a first resource balance of the first account by a first quantity and save first data obtained through a consensus into the first blockchain based on execution of the first transaction, where the first data includes an authenticable message; and sending the first data and first location information to the relay end, which is used to send the authenticable message to the second blockchain, where a second resource balance of the second account is incremented by a second quantity.
