Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-powered or remotely-located devices struggle to maintain synchronization with a blockchain due to energy and connectivity constraints, limiting the applicability of blockchain technology for these devices.
Innovation Solution
Broadcasting blockchain updates using RF signals, allowing devices to passively receive and store synchronization information, and enabling data authentication and upload when internet connectivity is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices maintain an active internet connection to synchronize with the blockchain, then synchronization reliability is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic RF broadcasts of blockchain state information at predetermined intervals, allowing devices to synchronize intermittently rather than maintaining continuous connections. Devices can wake up periodically to receive updates and then enter low-power mode, dramatically reducing energy consumption while maintaining synchronization reliability.
Solution Approach 2:
The patent introduces an RF broadcast intermediary that relays blockchain state information from the internet to devices. Instead of devices directly maintaining internet connections, they receive information through this intermediary via RF signals, eliminating the need for continuous high-power wireless internet connectivity while maintaining synchronization.
2Reliability
If devices download large amounts of blockchain information to remain synchronized, then synchronization completeness is improved, but data transmission requirements increase
Solution Approach 1:
The system extracts only the essential blockchain state information needed for synchronization and transmits it via RF broadcasts. Instead of requiring devices to download complete blockchain datasets, only the critical state changes are broadcast, dramatically reducing data transmission requirements while maintaining synchronization completeness.
Solution Approach 2:
The blockchain state information is prepared and encoded into RF broadcast messages in advance, before transmission to devices. This preliminary preparation allows the information to be delivered in compact, pre-processed form rather than requiring devices to retrieve and process large amounts of raw data, reducing transmission volume while ensuring completeness.
3Reliability
If devices maintain internet connectivity for real-time synchronization, then data freshness is improved, but device complexity increases
Solution Approach 1:
The RF broadcast system serves as an intermediary that simplifies connectivity management for devices. Instead of requiring complex internet connection management, devices simply receive broadcasts passively. The intermediary handles all connectivity complexity on the device side, maintaining data freshness through periodic broadcasts while reducing device complexity.
Solution Approach 2:
Devices can operate autonomously by listening for RF broadcasts and automatically updating their local blockchain state without requiring complex connection management. The system provides self-service synchronization where devices independently maintain freshness by receiving broadcasts at predetermined intervals, eliminating the need for complex connectivity management software or protocols.

AI summary
A method of synchronizing a device with a blockchain includes : receiving information about a first state of a blockchain; generating an RF broadcast signal encoding the information about the first state of the blockchain; and transmitting, at a first time, the first broadcast signal to the device. Similar methods for maintaining synchronization and for writing new data to a blockchain are also provided, as well as corresponding devices.
