Offline-Signed Blockchain Transactions via SMS Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain technology is hindered by the need for internet connectivity for node communication and transaction broadcasting, which is unreliable or non-existent in many regions, limiting its adoption.
Innovation Solution
Implementing a hybrid communication system using non-internet protocol methods such as SMS, FM/AM radio signals, and satellite transmissions to facilitate blockchain transactions, enabling users to interact with blockchain networks through mobile applications that prepare and sign transaction blocks offline, and relay them through intermittent internet-connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internet protocol communication is used for blockchain transactions, then transaction security and consistency are improved, but accessibility and reliability in regions with limited internet access deteriorate
Solution Approach 1:
The patent introduces an intermediary service that bridges non-internet protocol communications (SMS, radio, satellite) with the blockchain network. This intermediary handles the translation and relay of transaction data, enabling users in regions with limited internet access to participate in blockchain transactions while maintaining security and consistency through the intermediary's coordination between alternative communication channels and the blockchain protocol.
2Adaptability or versatility
If non-internet protocol transmissions are used, then accessibility in regions with limited internet access is improved, but communication reliability and transaction consistency deteriorate
Solution Approach 1:
The patent implements preliminary actions by having users prepare and sign transaction blocks offline using alternative communication channels (SMS, radio, satellite) before the actual transaction execution. The intermediary service pre-processes and validates these transactions, ensuring they are ready for consistent execution on the blockchain network, thereby maintaining reliability despite the use of less reliable communication channels.
Solution Approach 2:
The system incorporates feedback mechanisms where the intermediary service receives transactions via alternative protocols, validates them against blockchain consensus rules, and relays confirmed transactions back to users through the same channels. This feedback loop ensures that only consistent and valid transactions are processed, maintaining communication reliability and transaction integrity even when using less reliable non-internet protocols.

AI summary
The present technology pertains to a hybrid communication blockchain transaction communication system and method of using the same. A method is disclosed for facilitating internet-less blockchain transactions. The method involves an application sending an SMS message requesting a coin object with a minimum value, identifying the sender's wallet address, and storing the coin object on a blockchain. The application then receives an SMS with the coin object identification, versioned ID, and digest. The application captures user input to define the recipient wallet address and transaction type. It sends a third SMS containing the sender's signature and transaction details, including the sender's wallet address, coin object ID as gas input, recipient wallet address, and transaction type. The application receives a fourth SMS with a transaction digest, confirming the transaction has been recorded on the blockchain.
