Cryptocurrencies have revolutionized digital transactions by leveraging decentralized blockchain technology to ensure transparency, immutability, and security. However, one persistent challenge remains: verifying the authenticity of public key addresses associated with users. Without reliable mechanisms, users risk sending funds to fraudulent or compromised addresses. The patent CN104320262A introduces a robust system for securely binding, retrieving, and verifying user public key addresses using the inherent properties of public ledgers.
This article explores the technical architecture behind this method, its significance in enhancing trust within cryptocurrency networks, and how it supports secure digital identity management—all while maintaining full compliance with modern blockchain principles.
How Public Key Address Binding Works
In any cryptocurrency network, each user possesses a pair of cryptographic keys: a public key (used as an address to receive funds) and a private key (used to sign and send transactions). While transparency is a strength of blockchain systems, it also exposes vulnerabilities—anyone can generate an address, making impersonation possible without additional verification layers.
The method described in CN104320262A introduces a structured process for linking a user’s account to their public key address through verified on-chain transactions, ensuring authenticity and reducing fraud risks.
Step-by-Step Process
- Publishing a Verification Public Key Address
A trusted entity (such as a service provider or platform) publishes a known public key address. This becomes the reference point for all future verifications. - User Registration and Public Key Submission
When a user registers on the platform, they submit their cryptocurrency public key address. The system stores this information securely, associating it with the user's account. - Initiating a Verification Transaction
The system uses the private key corresponding to the published verification address to send a transaction—possibly zero-value—to the user’s submitted public key address. This transaction includes metadata (such as the username) in its script or附加 data field and is permanently recorded on the blockchain. Querying and Validating Addresses
When another user wants to verify a recipient's address:- They query the system using the recipient’s username.
- The system checks the blockchain for the existence of the verification transaction.
It validates whether:
- The sender matches the trusted verification address.
- The receiver matches the registered public key.
- The transaction contains the correct username in its metadata.
Only if all conditions are met is the address marked as secure and valid.

Core Technical Components of the System
The system outlined in the patent consists of three primary modules that work together to enable secure address binding and validation:
1. Registration and Verification Unit
This component handles incoming registration requests. It verifies user credentials (optionally including identity authentication) and securely stores the mapping between usernames and public key addresses.
2. Verification Transaction Unit
Responsible for initiating and broadcasting verification transactions onto the blockchain. These transactions serve as cryptographic proof that a specific public key belongs to a registered user.
3. Query and Retrieval Unit
Receives lookup requests from third parties seeking to validate a user's address. It performs real-time checks against the blockchain ledger and returns verified results only when all validation criteria are satisfied.
These components operate in harmony to create a tamper-proof, decentralized identity layer built directly on top of existing blockchain infrastructure—without requiring changes to underlying protocols.
Why This Method Enhances Security
Traditional systems often rely on centralized databases to map usernames to wallet addresses—an approach vulnerable to breaches and manipulation. In contrast, this method leverages the immutability of blockchain records to decentralize trust.
Key security advantages include:
- Tamper Resistance: Once a verification transaction is recorded, it cannot be altered or deleted.
- Transparency: Anyone can independently verify the authenticity of an address by inspecting the public ledger.
- Non-Repudiation: Since transactions are cryptographically signed, senders cannot deny having initiated them.
- Phishing Prevention: Users can confirm they are sending funds to legitimate recipients before executing high-value transfers.
This creates a more trustworthy ecosystem where users interact confidently, knowing that address spoofing attempts will be flagged during validation.
Real-World Applications
While initially designed for cryptocurrency platforms, this method has broader implications across multiple domains:
Digital Identity Management
Organizations can use verified blockchain transactions to bind digital identities to real-world entities, supporting Know Your Customer (KYC) compliance without storing sensitive data centrally.
Enterprise Payment Systems
Companies managing large volumes of crypto payments can automate vendor verification, reducing errors and fraud in supply chain financing.
Decentralized Finance (DeFi)
In DeFi applications, where users interact directly via smart contracts, ensuring correct wallet addresses prevents irreversible loss of assets due to human error.

Frequently Asked Questions (FAQ)
What is a public key address in cryptocurrency?
A public key address is a cryptographic identifier derived from a user’s public key. It functions like an email address—allowing others to send digital assets—but does not reveal private keys or personal information.
How does blockchain help verify user identities?
Blockchain provides an immutable record of transactions. By embedding identity-related data (like usernames) into verified on-chain transactions, systems can cryptographically prove ownership without relying on third-party intermediaries.
Can zero-value transactions be used for verification?
Yes. Even transactions with zero cryptocurrency value carry metadata and signatures, making them suitable for verification purposes. They incur minimal network fees but provide strong cryptographic assurance.
Is this method compatible with major blockchains?
Absolutely. The technique works with any blockchain supporting scriptable transactions or metadata inclusion—such as Bitcoin (via OP_RETURN), Ethereum, and other smart contract-enabled networks.
Does this system require users to reveal personal information?
No. The method binds usernames or identifiers to public keys without exposing personally identifiable information (PII). Privacy is preserved while still enabling trust through transparent validation.
How does this prevent scams?
By requiring a verifiable on-chain signal from a trusted source, scammers cannot simply copy-paste someone else’s address and claim legitimacy—the absence of a valid verification transaction will flag suspicious activity.
Advancing Trust in Decentralized Ecosystems
As digital economies grow more complex, so too must the tools we use to secure them. The method described in CN104320262A represents a foundational step toward building trustless yet trustworthy systems—where confidence stems not from authority, but from verifiable cryptographic evidence.
By integrating such mechanisms into wallets, exchanges, and DeFi protocols, developers can significantly reduce user risk while preserving decentralization.

Conclusion
Secure user public key address binding is not just a technical enhancement—it's a necessity in today’s digital economy. With rising threats from phishing, impersonation, and human error, robust verification systems are critical for mainstream adoption of cryptocurrencies.
The patented approach offers a scalable, decentralized solution that turns the blockchain itself into a tool for identity assurance. As more platforms adopt similar models, we move closer to a future where every transaction is not only fast and borderless—but also safe and verifiable.
