Blockchain Asset Transfer Event Recording via Rendezvous Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems lack efficient and secure protocols for recording asset transfer events, particularly in transactions involving diverse currencies and assets, which can lead to inconsistencies and difficulties in maintaining tamper-proof records.
Innovation Solution
A computer-implemented method that records asset transfer events by generating a rendezvous blockchain transaction, associating it with event streams, and using metadata to ensure secure and efficient transfer protocols, even across different asset registries and currencies, through the use of cryptographic signatures and provably unspendable outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional blockchain transaction validation is used, then transaction security is maintained through cryptographic validation, but the system lacks efficiency and versatility in handling diverse asset transfer events across different registries
Solution Approach 1:
The patent segments the transaction recording process into distinct components: event streams for different asset types, metadata structures for specific event properties, and standardized output formats. This allows the system to handle diverse asset transfer events (cryptocurrency, tokens, digital assets) through specialized segments while maintaining overall system integrity through the unified blockchain ledger.
Solution Approach 2:
The patent creates a universal transaction output structure that can represent multiple types of asset transfer events through standardized fields. The output includes generic event type identifiers, party information, and asset details that can accommodate cryptocurrency transactions, token transfers, and digital asset movements within a single unified framework, enabling the system to serve multiple functions across different asset registries.
2Reliability
If comprehensive metadata is collected for all asset transfer events, then transaction integrity and traceability are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The patent applies local quality by allowing metadata structures to be tailored to specific event types and asset categories. Different event streams can have customized metadata fields relevant to their particular asset type (e.g., cryptocurrency-specific fields vs. token-specific fields), while still conforming to the overall standardized output format. This reduces unnecessary complexity by only collecting relevant data for each specific transaction type.
Solution Approach 2:
The patent combines multiple metadata components into a composite transaction record structure. The output integrates event type identifiers, party information, asset details, and registry-specific metadata into a unified composite structure that maintains integrity through standardized formatting while accommodating the diversity of underlying data sources and asset types.
3Loss of information
If event streams are associated with chains of commitments for each user, then traceability and user-specific tracking are enhanced, but the quantity of data to be processed and stored increases
Solution Approach 1:
The patent extracts user-specific traceability information into separate event streams associated with each user's chain of commitments. By isolating individual user event streams from the general transaction ledger, the system maintains comprehensive traceability for each user while preventing the duplication of common transaction data across multiple user streams, thus reducing overall data volume.
Solution Approach 2:
The patent adds a dimensional layer to the blockchain data structure by creating event streams that exist alongside the main transaction ledger. This multi-dimensional approach allows traceability information to be organized by user chains of commitments rather than just by transaction sequence, enabling efficient querying and processing of user-specific data without requiring the entire ledger to be processed for each user inquiry.
4Adaptability or versatility
If standardized output formats are implemented for diverse event types, then interoperability between different asset registries is improved, but flexibility in representing unique event characteristics may be reduced
Solution Approach 1:
The patent implements a universal output format that serves multiple asset registry types through standardized event type identifiers and generic field structures. The same output template can represent cryptocurrency transfers, token movements, and digital asset transactions by varying the event type code and associated metadata, enabling interoperability across different registries without requiring separate processing logic for each asset type.
Solution Approach 2:
The patent uses parameter changes to adapt the standardized output format to different event types. By varying specific metadata parameters (event type, asset identifier format, registry-specific fields) while maintaining the overall structure, the system can represent unique event characteristics within the standardized framework, balancing interoperability with the ability to capture event-specific details.
