Innovation Solution
A method and system for secure asset transfer using blockchain technology that utilizes cryptographic keys and metadata hashing to enable peer-to-peer transactions without altering the underlying protocol, ensuring security, anonymity, and efficient data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used for secure transactions, then security and data integrity are improved, but versatility and adaptability for different asset types deteriorate
Solution Approach 1:
The patent implements a universal token standard that enables a single blockchain protocol to handle multiple asset types including cryptocurrencies, contracts, goods, and services. The tokenization framework provides a multi-functional platform where diverse real-world entities can be represented and transferred through standardized digital tokens, resolving the contradiction between maintaining security and achieving versatility.
2Reliability
If traditional trusted third parties are used for asset transfer, then transaction security is improved, but system complexity and intermediary requirements worsen
Solution Approach 1:
The patent implements self-service mechanisms through automated smart contracts that execute transactions autonomously without requiring trusted third parties. The blockchain network itself provides the security and validation functions previously performed by intermediaries, eliminating system complexity while maintaining transaction security through decentralized consensus and cryptographic verification.
3Reliability
If detailed transaction data is recorded on blockchain, then data integrity and transparency are improved, but privacy and anonymity deteriorate
Solution Approach 1:
The patent segments transaction data into on-chain and off-chain components. Essential transaction metadata that ensures data integrity and transparency is recorded on the blockchain, while sensitive private information is stored off-chain or encrypted. This segmentation allows the system to maintain both data integrity through public verification and privacy through selective data exposure.
Data Source
AI summary
The invention provides a secure method for exchanging entities via a blockchain. The invention incorporates tokenisation techniques, and also techniques for embedding metadata in a redeem script of a blockchain transaction. Embodiment(s) provide a method of: generating a first script, the first script comprising: a first set of metadata associated with a first invitation for the exchange of a first entity by a first user, the first set of metadata comprising an indication of the first entity to be offered for exchange and a first location condition for the exchange, a first user public key (P1A) associated with the first user, wherein the first user public key (P1A) is part of an asymmetric cryptographic pair comprising the first user public key (P1A) and a first user private key (V1A). The script may further comprise a first third-party public key (P1T) associated with a first third-party.
