Secure Cryptoasset Component for Blockchain Namespace Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain platforms lack sufficient security for cryptoassets, making them vulnerable to malicious actors, especially in industries handling sensitive information like healthcare where monetary transactions are critical.
Innovation Solution
Implementing a secure cryptoasset component on top of blockchain platforms, such as Hyperledger Sawtooth, using a namespace mechanism to separate and protect coin balances, and utilizing smart contracts to ensure program correctness and transaction security, along with a token standard for secure transactions like 'transfer', 'approve', and 'transfer_from' to manage cryptoassets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a blockchain platform does not have a cryptocurrency, then the platform can be used for various transactions across industries, but it cannot provide secure cryptoasset functionality for monetary transfer and security
Solution Approach 1:
The patent divides the blockchain system into separate functional components: a namespace mechanism for isolating coin accounts, smart contracts for transaction logic, and a token standard for secure transfers. This segmentation allows the platform to maintain versatility while providing dedicated secure functionality for cryptoassets through independent modules that can be activated as needed.
Solution Approach 2:
The patent introduces a secure cryptoasset component as an intermediary layer between the blockchain platform and cryptocurrency transactions. This intermediary provides the necessary security mechanisms (namespace isolation, smart contract validation, token standard enforcement) without requiring the underlying platform to have native cryptocurrency functionality, thus maintaining platform versatility while enabling secure monetary transfers.
2Reliability
If cryptoassets are made more secure through additional safeguards, then security against malicious actors improves, but system complexity increases
Solution Approach 1:
The patent designs the secure cryptoasset component to serve multiple functions through a unified system: the namespace mechanism handles account isolation and access control, the smart contracts manage transfer logic and validation, and the token standard provides a common interface for secure transactions. This multi-functionality reduces overall system complexity compared to implementing separate security mechanisms for each function.
Solution Approach 2:
The patent changes the parameters of the blockchain system by introducing a dedicated namespace for coin accounts, which isolates cryptographic operations from other transactions. This parameter change (creating a separate namespace) provides enhanced security without requiring fundamental changes to the underlying blockchain architecture, thus improving reliability while controlling complexity.
3Reliability
If namespace mechanism is used to separate coin accounts, then unauthorized access to coin balances is restricted, but transaction processing complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the namespace structure automatically enforces access control rules without requiring manual intervention. The smart contracts automatically validate transactions against the namespace isolation rules, and the token standard automatically manages transfer operations. This automation restricts unauthorized access while minimizing the operational complexity for transaction processing.
