Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in managing and transferring digital assets across multiple blockchain ecosystems due to the need for native tokens for transactions, which creates barriers to entry and limits interoperability, and existing methods like bridge applications can lead to confusion and errors as the number of assets and blockchains increases.
Innovation Solution
A multi-blockchain trading system that tightly couples a target blockchain with host blockchains using messaging protocols, enabling token deposits, withdrawals, transfers, and swapping through smart contracts and third-party bridge applications, with automatic gas abstraction and balance management to facilitate seamless transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users acquire native tokens of each blockchain to execute transactions, then they can perform operations on the network, but this creates a barrier to entry and limits interoperability between different blockchain ecosystems
Solution Approach 1:
The patent implements a universal gas token system where a single native token of the host blockchain can be used to pay for transactions across multiple interconnected blockchains. The messaging protocol enables the host blockchain's gas token to function universally across the network, eliminating the need for users to acquire separate native tokens for each blockchain they interact with.
Solution Approach 2:
The patent introduces a messaging protocol as an intermediary layer between the host blockchain and target blockchains. This protocol carries transaction information and gas token references across blockchain boundaries, enabling seamless interoperability without requiring users to directly manage multiple native tokens. The messaging system acts as a mediator that translates and routes transactions between different blockchain ecosystems.
2Adaptability or versatility
If bridge applications or wrapping tokens are used to transfer assets between blockchains, then asset transfer is enabled, but confusion and potential errors increase as the number of assets and blockchains involved increases
Solution Approach 1:
The patent merges the asset transfer functionality into the native messaging protocol of the blockchain network. Instead of using separate bridge applications for each asset transfer, the messaging protocol handles all cross-chain transactions uniformly. This consolidation reduces the number of separate systems users must manage and decreases the likelihood of errors from using multiple different bridge solutions.
Solution Approach 2:
The messaging protocol serves multiple functions: it transfers assets between blockchains, tracks gas token balances, updates smart contract states, and manages cross-chain transactions. This multi-functional approach eliminates the need for separate specialized bridge applications for each type of operation, reducing complexity and potential error sources.
3Adaptability or versatility
If multiple separate bridge applications are used to manage assets across multiple blockchains, then asset management is possible, but the complexity of managing assets across multiple platforms increases
Solution Approach 1:
The patent creates a universal system where the host blockchain's messaging protocol and gas token system work across all connected target blockchains. Users interact with a single host blockchain interface to manage assets across multiple chains, eliminating the need to separately manage multiple bridge applications. The system provides unified asset management while maintaining compatibility with diverse blockchain networks.
4Adaptability or versatility
If traditional bridge applications are used for cross-chain transactions, then asset transfer is enabled, but transaction costs and friction increase
Solution Approach 1:
The messaging protocol acts as an efficient intermediary that enables direct cross-chain transactions without requiring multiple intermediate bridge applications. By using a standardized messaging format and the host blockchain's existing gas token system, the protocol reduces transaction overhead and costs compared to traditional multi-step bridge processes.
