Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain technologies are limited in their versatility and require trusted third parties for secure transactions, lacking efficient mechanisms for the exchange and control of diverse assets beyond cryptocurrencies.
Innovation Solution
A blockchain-based method utilizing cryptographic keys and tokenization techniques to securely transfer and control assets, embedding metadata in scripts to facilitate peer-to-peer exchanges without altering the underlying protocol, ensuring data integrity and anonymity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used for cryptocurrency transactions, then security and decentralization are improved, but versatility for diverse asset exchanges deteriorates
Solution Approach 1:
The patent implements a universal tokenization framework that enables the blockchain to represent and exchange multiple types of assets (cryptocurrencies, commodities, securities, real estate) through a common token structure. The system defines standardized token attributes including issuer, denomination, and metadata fields that can accommodate diverse asset classes, allowing the blockchain to function as a multi-asset exchange platform while maintaining security and decentralization
2Reliability
If trusted third parties are introduced for secure transactions, then transaction security is improved, but system complexity and reliance on intermediaries worsens
Solution Approach 1:
The patent implements self-service mechanisms where the blockchain system autonomously verifies and executes asset exchanges through programmed smart contracts and validation rules. The tokenization framework includes built-in validation logic that automatically checks transaction legitimacy, asset ownership, and exchange conditions without requiring external intermediaries, thereby maintaining security while reducing system complexity
3Productivity
If metadata is embedded in blockchain scripts, then asset exchange efficiency is improved, but computational requirements worsen
Solution Approach 1:
The patent segments metadata into hierarchical levels: essential validation data (issuer, denomination) is embedded directly in the token script for efficient verification, while detailed asset information is stored in external databases and referenced through hashes. This segmentation allows rapid transaction validation using minimal embedded data while maintaining comprehensive asset representation, thereby improving exchange efficiency without excessive computational burden

AI summary
A secure method for exchanging entities via a blockchain is presented. The method comprises receiving, from a user over a communications network, an invitation to perform an exchange of entities; generating a redeem script comprising metadata; hashing the redeem script to generate a redeem script hash; sending the first script and the first script hash on a distributed hash table (DHT); and generating an invitation transaction comprising an output associated with an encrypted digital asset, and a hash of a script comprising an indication of entities to be exchanged, conditions for the exchange, and a public cryptographic key associated with the user.
