Solution Overview
Problem
Current blockchain and cryptocurrency systems face challenges in securely linking identity to transactions without compromising user privacy, leading to vulnerabilities such as money laundering and illicit activities.
Innovation Solution
The implementation of Zero-Knowledge Proof (ZKP) technology, combined with enhanced identity credentials and BIP-47/OBPP-5 payment codes, allows users to prove ownership of private keys and associated identities, ensuring secure and transparent transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional KYC protocols are used for identity verification, then identity security is improved, but integration with decentralized blockchain transactions deteriorates
Solution Approach 1:
The patent introduces Zero-Knowledge Proof (ZKP) as an intermediary mechanism that bridges traditional KYC identity verification systems and decentralized blockchain transactions. ZKP enables identity credentials to be verified on-chain without requiring centralized KYC infrastructure, allowing decentralized applications to perform identity verification natively while maintaining compatibility with existing identity systems.
Solution Approach 2:
The patent replaces the mechanical centralized KYC verification system with a cryptographic ZKP-based verification mechanism. Instead of relying on centralized databases and manual verification processes, the system uses cryptographic proofs to verify identity credentials directly on the blockchain, eliminating the need for centralized intermediaries while maintaining verification reliability.
2Loss of information
If wallet anonymity is maintained, then user privacy is improved, but ability to verify legitimate identity deteriorates
Solution Approach 1:
The patent extracts the identity verification function from the transaction data itself. Instead of embedding personal identifiable information in transactions, the system separates identity proof (ZKP credentials) from transaction execution. This allows the blockchain to verify identity legitimacy without storing or exposing sensitive user information, maintaining privacy while enabling verification.
Solution Approach 2:
The patent changes the verification parameter from checking actual identity data (names, addresses) to verifying cryptographic proofs of identity credentials. This parameter transformation allows the system to confirm legitimate identity without revealing or storing sensitive information, resolving the contradiction between privacy and verification capability.
3Reliability
If centralized custodial systems are used, then transaction security is improved, but susceptibility to money laundering deteriorates
Solution Approach 1:
The patent enables decentralized identity verification where the system itself performs verification through ZKP mechanisms without requiring centralized custodial intermediaries. Each transaction can independently verify the sender's identity credentials through cryptographic proofs, eliminating the single point of failure and vulnerability to money laundering that exists in centralized systems.
Solution Approach 2:
The patent introduces ZKP credentials as an intermediary layer between senders and centralized custodial systems. Instead of relying solely on centralized systems to filter illicit funds, the ZKP credential system provides an additional verification layer that proves the legitimacy of fund sources before transactions enter centralized systems, reducing money laundering vulnerability.

AI summary
A cryptocurrency system with a communication channel, a wallet, where the wallet has a paycode and associated private key and the paycode is associated to enhanced identity. The wallet can send a zero knowledge proof on the communication channel to prove ownership of the private key and thus proof of the enhanced identity information. The wallet may include a blockchain address and associated private key. The wallet may send a zero knowledge proof on the communication channel to prove ownership of the blockchain address and thus provide proof of funds. The cryptocurrency system may include a communication channel, a wallet with a private key, where the wallet can send a zero knowledge proof on the communication channel to prove control of the private key.
