Blockchain Wallet Plugin Sandbox for Secure Custom Extensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain wallets lack an efficient method to add custom functionalities without compromising security, making it difficult for companies to tailor the wallet for specific use cases like government agencies or healthcare without introducing security risks.
Innovation Solution
A sandbox environment is provided that communicates through a secure message gateway, allowing plugins to extend blockchain wallets by isolating custom functionalities, ensuring they do not compromise the security of the base wallet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If plugins are integrated directly into the blockchain wallet, then custom functionalities can be added, but security risks are introduced
Solution Approach 1:
The system divides the wallet into a secure core and separate plugin modules. Each plugin is isolated in its own sandbox environment, allowing custom functionalities to be added without compromising the core wallet security. The sandbox acts as a boundary that segments the plugin code execution from the main wallet process.
Solution Approach 2:
A sandbox environment serves as an intermediary layer between the plugin code and the blockchain wallet core. This intermediary provides a controlled execution space where plugins can operate with limited access to system resources, preventing direct security breaches while still enabling custom functionality.
2Reliability
If a sandbox environment is introduced to isolate plugins, then security is maintained, but device complexity increases
Solution Approach 1:
The sandbox environment is designed as a universal isolation mechanism that can handle multiple types of plugins and custom functionalities through a single standardized interface. This multi-functional approach reduces overall system complexity by using one pattern for various security isolation needs rather than creating separate mechanisms for each plugin type.
3Reliability
If plugins communicate through a secure message gateway, then security is enhanced, but ease of operation decreases
Solution Approach 1:
The plugin system includes self-service mechanisms where plugins automatically declare their communication needs and required permissions. The system automatically configures the secure message gateway connections and access rights based on plugin metadata, eliminating the need for manual security configuration and simplifying the integration process.

AI summary
Various aspects of the subject technology relate to systems, methods, and machine-readable media for extending and customizing a blockchain wallet. Various aspects may include providing, to users of a blockchain platform, a blockchain wallet configured to provide standard services to the users, and, providing, to the users, a sandbox environment that only communicates with the blockchain wallet through a secure message gateway. Aspects may also include storing, in the sandbox environment, a plugin configured to provide add-on services, and executing the plugin within the sandbox environment to enable the plugin to provide, as an extension of the blockchain wallet through the secure message gateway, the add-on services to the plurality of users.
