Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital transaction platforms face issues such as lack of security and transparency, complex user interfaces, inability to verify trust between parties in multi-party transactions, and limitations in creating and accepting diverse tokens, which hinder their acceptance in broader lending and payment systems, especially for marginalized groups and small businesses.
Innovation Solution
A system and method that utilizes a processor and digital ledger to generate and manage token specifications, verify transactions, and facilitate transfers between multiple issuers and recipients, providing a secure and transparent environment for digital transactions while maintaining data privacy through smart contracts and digital wallets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital transaction platforms use complex security and data privacy safeguards, then security and transparency are improved, but system complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a blockchain-based intermediary layer that mediates between users and transaction processors. The blockchain ledger acts as a trusted third party that automatically verifies and records transactions, eliminating the need for complex centralized security systems while maintaining transparency and security through distributed consensus mechanisms.
Solution Approach 2:
The system enables self-service through smart contracts that automatically execute transaction rules and verification processes. The blockchain network itself performs security verification and transaction validation without requiring complex external security infrastructure, allowing the system to secure itself through cryptographic protocols and consensus algorithms.
2Adaptability or versatility
If digital transaction platforms support multiple token classes and issuers, then adaptability and versatility are improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent creates a universal token standard that allows multiple token classes and issuers to operate on a single platform. The blockchain system provides a unified framework that can accommodate diverse token types (utility tokens, security tokens, gift cards, etc.) while maintaining consistent verification and transaction processing rules, enabling one system to serve multiple functions.
Solution Approach 2:
The system uses parameter-based token definitions where each token class is defined by a set of parameters (issuer, value, redemption terms, etc.) rather than requiring separate system infrastructure. This allows the platform to adapt to different token types by simply changing parameter values while maintaining the same underlying transaction and verification mechanisms.
3Reliability
If digital transaction platforms verify trust between parties in multi-party transactions, then reliability is improved, but measurement precision and difficulty of detecting and measuring worsen
Solution Approach 1:
The blockchain system provides continuous feedback through the immutable ledger that records all transactions and trust relationships. Each transaction verifies and reinforces trust between parties by creating a permanent, verifiable record that can be independently audited. The consensus mechanism provides feedback loops that validate trust assumptions across the network.
Solution Approach 2:
The patent replaces mechanical trust verification systems (manual background checks, intermediary verification) with cryptographic verification mechanisms. Trust is established through digital signatures, hash functions, and consensus protocols that automatically verify party identities and transaction authenticity without requiring human judgment or complex detection processes.
4Reliability
If digital transaction platforms maintain data privacy safeguards while providing transparency, then security is improved, but loss of information increases
Solution Approach 1:
The patent segments transaction information into different layers: public ledger data that provides transparency for verification, and private data that remains confidential. The blockchain records transaction hashes, amounts, and timestamps publicly for transparency, while sensitive information like personal identifiers and detailed transaction purposes can be kept private through encryption or zero-knowledge proofs, allowing both transparency and privacy to coexist.
Solution Approach 2:
Different parts of the transaction data have different privacy qualities. The system allows public visibility of transaction existence, amount, and parties involved for transparency, while enabling private storage of sensitive personal information, authentication credentials, and detailed transaction purposes. This local differentiation of information quality allows simultaneous achievement of transparency and privacy.
Data Source
AI summary
A system that can transfer tokens of multiple classes from issuers to recipients is disclosed. The system generates class-specific token specification that include parameters that must be satisfied for the first user to acquire, from another user of the system, any token that is created according to the class-specific token specification. The system will save the records for each of the class-specific token specifications to a digital ledger that is accessible to users of the system. When a transfer request is received for a particular token, the system will execute a smart contract by (a) accessing the digital ledger to verify that a class-specific token specification exists which corresponds to the class of the particular token, and (b) in response to the verifying write, to the digital ledger, a first ledger entry that includes a record indicating that the amount of the particular token has been transferred to the recipient.
