Digital Twin Monitoring of Cross-Chain Smart Contract States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to provide a consolidated view and observability into multiple smart contracts operating across different administrative domains and ledgers, especially in a decentralized Web3 environment, where there is no centralized point of control, leading to challenges in monitoring and ensuring correct operation and interaction between cross-chain smart contracts.
Innovation Solution
A digital twin system is employed to receive data from multiple smart contracts and oracles associated with different distributed ledgers, generating a consolidated view and models to monitor and predict the operating states and interactions of these contracts, using out-of-band communication to ensure data integrity and visibility across disparate systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a decentralized distributed ledger system is used to store smart contracts across multiple administrative domains, then data immutability and trustlessness are improved, but the ability to provide a consolidated view and monitor interactions between contracts deteriorates
Solution Approach 1:
The patent introduces an intermediary system that connects multiple distributed ledgers and smart contracts across different administrative domains. This intermediary enables the consolidation of contract states and interaction data without centralizing control, thereby maintaining data immutability while providing a unified view for monitoring and analysis.
Solution Approach 2:
The system segments the consolidated view functionality into modular components that can operate across distributed ledgers independently. Each ledger maintains its own smart contracts and state, while the segmentation allows selective aggregation of specific contract interactions and states into a consolidated view without requiring centralized control.
2Adaptability or versatility
If smart contracts operate independently across different administrative domains without centralized control, then trustlessness and autonomy are improved, but the complexity of monitoring and ensuring correct operation deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the monitoring system observes smart contract executions across different administrative domains and provides feedback information about contract states and interactions. This feedback enables automatic detection of issues and coordination between independent contracts without requiring complex centralized control, thereby reducing monitoring complexity while maintaining contract autonomy.
3Reliability
If multiple distributed ledgers are used to store smart contracts in different administrative domains, then system reliability and decentralization are improved, but the difficulty of detecting and measuring contract interactions deteriorates
Solution Approach 1:
The patent introduces intermediary components that bridge multiple distributed ledgers, enabling the detection and measurement of smart contract interactions across different administrative domains. These intermediaries capture and standardize interaction data from various ledgers, making it possible to observe and analyze contract behaviors without compromising system decentralization or reliability.
Data Source
AI summary
Presented herein are techniques for observing smart contracts. A method can include obtaining, by a digital twin, a first data set from a first smart contract that stores the first data to a first distributed ledger and a second data set from a second smart contract that stores the second data set to a second distributed ledger. Determining operating states of the first and second smart contracts based on the first data set, the second data set, and one or more state messages from an oracle associated with the first distributed ledger and the second distributed ledger. Generating a consolidated view of the first and second smart contracts, based on the operating states. And providing the consolidated view of the first and second smart contracts for monitoring the operating states and interactions between the first and second smart contracts as a whole.
