Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Blockchain technologies face challenges in efficiently managing and synchronizing time-stamped transactions across multiple chains in IoT environments, particularly in ensuring accurate and sustained time signals for secure data sharing and journaling within Smart Contract mechanisms.
Innovation Solution
The implementation of a Multi-Chain Time (MCT) synchronization protocol, which uses a customized time protocol based on IEEE 1588-2008 Precision Time Protocol, synchronizes device chain and event chain time signals without relying on a grandmaster clock or GPS, ensuring unified time series performance and backward compatibility, allowing for islanded operation and mission-critical system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a grandmaster clock or GPS is used for time synchronization in blockchain multi-chain systems, then time synchronization accuracy is improved, but system reliability deteriorates due to external dependency and potential network interruptions
Solution Approach 1:
The patent introduces a time envelope mechanism as an intermediary layer between transactions and blockchain blocks. This time envelope contains time-stamped transaction data and allows transactions to be buffered and processed in chronological order without requiring continuous external time signals. The time envelope acts as a local time-keeping mechanism that maintains synchronization accuracy while enabling islanded operation during network interruptions.
Solution Approach 2:
The system performs preliminary time-stamping of transactions before they are included in blocks. By embedding time information in the time envelope at the transaction level rather than relying on real-time external time signals during block processing, the system prepares time-synchronization data in advance, allowing it to operate reliably even when external time sources are unavailable.
2Device complexity
If traditional blockchain block structure is used, then simplicity is maintained, but time-sequenced transaction processing across multiple chains deteriorates
Solution Approach 1:
The patent implements a nested structure where time envelopes are embedded within blockchain blocks. Each block contains one or more time envelopes, and each time envelope contains multiple time-stamped transactions. This nested organization allows the system to maintain the traditional blockchain block structure while adding time-sequencing capability through the embedded time envelope layer, enabling efficient chronological processing without fundamentally changing the blockchain architecture.
3Measurement precision
If time synchronization relies on external time sources, then time accuracy is improved, but adaptability deteriorates due to network dependency
Solution Approach 1:
The system cushions against network interruptions by buffering transactions in time envelopes with embedded time stamps before they need to be processed. This preliminary time-stamping creates a cushion of time-information that allows the blockchain to continue operating and maintaining chronological order even when external time sources are unavailable, providing adaptability to network conditions while preserving time accuracy.
Data Source
AI summary
A system for a shared and synchronous time series identification that matches a hardware clock-generating signal of a blockchain identified node device, with a generated data event time stamp and shared by all computing nodes participating in a complete system based on a blockchain design pattern and protocol. A blockchain cybersecurity system time signature is applied to synchronize the device level ID or device chain; this time sync is matched to the client master clocking time signal governing data transactions on the data event level or event chain. The combination of these two disparate blockchain mechanisms is termed as a multi-chain application. The matched time signals now provide referenced smart contract time sequencing. This matched time sequencing is unique and customized in its application to a multi-chain block chain cyber security application.
