Isolated Wallet Blockchain Updates Using Limited-Length Strings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Isolated digital assets storage devices, such as cryptocurrency wallets, are vulnerable to network-based attacks due to their disconnection from the network, making it difficult to update their internal balances with transactions recorded on the blockchain without network connectivity.
Innovation Solution
The isolated device infers transaction identifiers and updates its balance using limited length strings and predefined order information from a depository of previous transactions stored on networked devices, allowing it to synchronize with the blockchain without direct network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the isolated device is disconnected from the network to enhance security, then protection against network-based attacks is improved, but the ability to update transaction balances is worsened
Solution Approach 1:
The patent introduces an intermediary mechanism where transaction information is transmitted to the isolated device through a limited interface (such as a display screen and user input device) rather than through direct network connection. This allows the device to receive balance update information without establishing network connectivity, thus maintaining security while enabling reliable balance updates.
Solution Approach 2:
The patent extracts the network communication functionality from the isolated device, allowing only essential information display and input capabilities to remain. The device maintains isolation from the network while still receiving necessary transaction data through the limited interface, separating the security function from the data update function.
2Object-affected harmful factors
If manual data input is used to update balances in isolated devices, then security is maintained, but time consumption and operational complexity increase
Solution Approach 1:
The patent implements self-service functionality where the isolated device automatically receives and processes balance update information through the limited interface without requiring manual data entry. The device autonomously updates its internal balance based on transaction information transmitted through the interface, eliminating time-consuming manual operations while maintaining security.
Solution Approach 2:
The patent establishes a feedback mechanism where the isolated device receives transaction information, processes it automatically, and updates its balance accordingly. This closed-loop system eliminates the need for manual data input by automatically feedback-ing the balance updates to the user interface, significantly reducing operational time.

AI summary
Described herein are methods and devices for updating digital assets transactions in an isolated device, comprising the isolated device (1) receiving limited length string(s) indicating a value of digital assets transferred from one or more other devices to an account associated with the isolated device in one or more transactions each recorded in a blockchain with a respective identifier computed based on input value(s) of the respective transaction which corresponds to output value(s) of previous transaction(s) which the isolated device is informed of and are stored in a predefined order in a depository allocated for the isolated device in the other device(s), (2) inferring the respective identifier of each transaction according to the output value(s) of the previous transaction(s) identified based on the transferred value according to the predefined order and, (3) updating the isolated device with a digital assets balance of the associated account according to the transaction(s).
