Virtual Keyboard Cryptocurrency Wallet Intermediary Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual keyboard services require on-chain interaction for users to access and manage cryptocurrency assets, which is inconvenient and limits user experience, especially in the context of blockchain-based services like NFTs and cryptocurrency rewards.
Innovation Solution
Creating on-chain and off-chain matching user wallets that allow users to access blockchain services without direct on-chain interaction, using a service provider as an intermediary for wallet management and cryptocurrency storage, enabling cryptocurrency mining and rewards based on keyboard usage and NFTs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users directly manage on-chain wallets to access cryptocurrency assets, then security and control are improved, but user convenience and ease of operation deteriorate due to complex on-chain interaction requirements
Solution Approach 1:
The service provider acts as an intermediary by creating and managing on-chain wallets on behalf of users. The provider generates wallet addresses, stores private keys securely, and handles blockchain interactions, allowing users to access cryptocurrency assets through a simplified interface without directly managing complex on-chain operations.
Solution Approach 2:
The system creates a virtual representation of the on-chain wallet that users can interact with offline. This virtual wallet copy mirrors the actual blockchain wallet state, allowing users to manage assets through familiar digital wallet interfaces without requiring understanding of blockchain technicalities.
2Adaptability or versatility
If users directly interact with blockchain networks to manage cryptocurrency assets, then autonomy and control are improved, but system complexity and difficulty of operation worsen
Solution Approach 1:
The service provider serves as a mediator between users and the blockchain network, abstracting away the complexity of wallet management, transaction signing, and network interactions. Users retain autonomy over their assets through controlled access mechanisms while the provider handles technical complexity.
Solution Approach 2:
The system separates wallet management functions into distinct layers: the service provider handles on-chain wallet creation and private key management, while users control access through authentication credentials. This segmentation allows each party to operate within their comfort zone without exposing users to blockchain complexity.
3Productivity
If virtual keyboard service integrates blockchain technology for cryptocurrency rewards, then user engagement and service differentiation are improved, but service complexity and operational difficulty worsen
Solution Approach 1:
The system merges the virtual keyboard service with blockchain-based reward mechanisms by integrating cryptocurrency wallet functionality directly into the keyboard application. Users earn cryptocurrency rewards through keyboard usage while the service provider manages both the keyboard service and wallet operations through a unified platform.
Solution Approach 2:
The service provider platform performs multiple functions: it provides the virtual keyboard service, manages user authentication, creates and secures cryptocurrency wallets, distributes rewards, and handles customer support. This multi-functionality consolidates complexity into a single service provider rather than requiring users to manage separate systems.

AI summary
Disclosed herein are a method for providing a virtual keyboard service that pays cryptocurrency rewards using a user wallet provided by a service provider and an apparatus using the same. The method and apparatus may create an on-chain user wallet and an off-chain-based virtual blockchain user wallet which match each other and lend the created user wallets to a user who uses the virtual keyboard service, provide cryptocurrency that is mined while the user uses the virtual keyboard service to the virtual blockchain user wallet, and provide an on-chain service to the user by linking the on-chain user wallet with the virtual blockchain user wallet at preset link timing.
