Solution Overview
Problem
Users of cryptocurrency face challenges in managing self-custody due to technical complexities and security concerns, and existing devices for self-custody are often underutilized and inefficient in power consumption.
Innovation Solution
A cryptocurrency management device (CMD) with a fingerprint sensor and near-field communication (NFC) capabilities that automatically awakens upon user interaction or proximity, allowing for secure and efficient management of cryptocurrency transactions without continuous power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the CMD remains continuously powered on for immediate transaction processing, then transaction speed and responsiveness are improved, but battery life and energy efficiency deteriorate
Solution Approach 1:
The CMD implements periodic action by transitioning between active and sleep states. The device remains in sleep mode during extended inactivity to conserve battery power, then activates periodically when triggered by user interaction (fingerprint sensor, button press, or NFC proximity detection). This periodic on-off operation resolves the contradiction by providing responsive transaction processing only when needed while minimizing energy consumption during idle periods.
2Use of energy by moving object
If the CMD enters sleep mode to conserve battery power, then energy efficiency is improved, but transaction response time and operational readiness deteriorate
Solution Approach 1:
The CMD applies preliminary action by maintaining certain components in a ready state even during sleep mode. Specifically, the fingerprint sensor, button input circuitry, and NFC antenna remain capable of detecting user interaction or approaching devices while the main processor sleeps. When triggered, the processor quickly awakens and initiates transaction processing, minimizing delay while preserving battery power during idle periods.
3Ease of operation
If the device provides continuous access to cryptocurrency transactions, then ease of operation is improved, but security risks from unauthorized access increase
Solution Approach 1:
The CMD uses biometric authentication (fingerprint sensor) and NFC proximity verification as intermediaries between the user and cryptocurrency transactions. These intermediary verification layers ensure that only authorized users can access and initiate transactions, maintaining security while preserving ease of operation through quick fingerprint-based authentication and proximity-based device pairing.

AI summary
A cryptocurrency management device (CMD) may be used to perform various cryptocurrency management functions, such as storage of cryptocurrency, user authentication, and initiation or processing of a transaction for transferring cryptocurrency. To conserve the power resources of the CMD, components of the CMD may be transitioned to a sleep state for extended periods of time. Such components may be automatically activated by a user touching the CMD or bringing a wireless communication device within range of the CMD. The circuitry of the CMD that triggers the activation are capable of continuously monitoring for such inputs over extended periods of time without consuming significant amounts of power, thereby conserving the power resources of the CMD.
