In the rapidly evolving world of blockchain and digital assets, securing cryptocurrency holdings has become a top priority for individuals and organizations alike. One of the most critical aspects of this security lies in wallet address permission management—a sophisticated approach to controlling access, transfers, and recovery processes within blockchain wallets.
This article explores a comprehensive method for managing permissions across associated wallet addresses, originally detailed in patent CN108256842A. We’ll break down its core mechanisms, benefits, and real-world applications while integrating essential SEO keywords such as blockchain wallet security, address permission control, delayed transaction, private key recovery, multi-signature authorization, wallet address management, and CA certificate integration.
Understanding the Core Concept
At its foundation, this permission management system introduces a structured framework where multiple wallet addresses are linked under defined roles and functional capabilities. These roles include:
- User Address (A): The primary wallet controlled by the user.
- Existing Addresses (B, C, D…N): Additional addresses that may belong to the same user or third parties.
- New User Address (G): A backup address used when the original private key is lost.
- High-Permission Address (H): An administrative-level address with elevated control rights.
Each address operates under a set of programmable functions designed to enhance both usability and security.
Key Functionalities Explained
🔐 Authorization and Transfer Control
One of the standout features is the authorized transfer function, which allows a user’s main address (A) to grant withdrawal rights to one or more existing addresses (B, C, etc.). This enables seamless fund access across multiple accounts without transferring ownership—ideal for team-managed wallets or decentralized finance (DeFi) operations.

⏳ Delayed Transaction Mechanism
The system supports two types of delayed transactions:
- Reversible Delayed Transfer:
A user can schedule a future withdrawal from their wallet. Crucially, they retain the right to cancel this instruction before execution—offering a safety net against unauthorized or mistaken transactions. - Multi-Signature Delayed Transfer:
For higher-security environments, multiple authorized addresses must jointly approve a delayed transfer. This adds an extra layer of consensus-based control, reducing the risk of single-point failures.
These mechanisms align closely with modern best practices in transaction finality control and risk mitigation.
🛡️ Private Key Recovery Process
Losing a private key often means permanent loss of funds—a major pain point in crypto adoption. This method introduces a robust private key recovery workflow:
- The user requests revocation of the CA (Certificate Authority) certificate tied to the compromised address.
- The blockchain system automatically freezes all assets on that address.
- After a predefined period, funds are transferred to a pre-registered new address (G), secured with a newly issued CA certificate.
This process ensures that even if a private key is lost or stolen, asset recovery remains possible under controlled conditions.
🔧 Hierarchical Permission Management
Two main subsystems govern access rights:
1. High-Permission Address Controls
The high-permission address (H) acts as a supervisory entity capable of:
- Revoking pending transactions
- Freezing private key usage
- Issuing commands on behalf of the user
- Setting spending limits and whitelisting/blacklisting recipients
This is particularly useful in enterprise settings where compliance and oversight are mandatory.
2. Certificate Authority (CA) Integration
Users can delegate specific powers to one or more CA centers, including:
- Authority to freeze funds
- Right to revoke transactions
- Control over transfer amounts and time windows
- Management of免signature payment thresholds (small-value transactions without full authentication)
By decentralizing trust through multiple CAs, the system enhances resilience against single-point manipulation.
Seamless Address Switching
Another practical benefit is the free address switching capability. If multiple addresses belong to the same user, the wallet interface allows instant toggling between them—streamlining portfolio management across different use cases (e.g., trading, savings, DeFi staking).
This improves user experience without compromising security architecture.
FAQ: Common Questions Answered
Q1: How does this method prevent unauthorized fund withdrawals?
The combination of delayed transfers, multi-signature approvals, and CA-based freezing creates multiple checkpoints before any withdrawal executes. Even if a hacker gains partial access, they cannot bypass all layers simultaneously.
Q2: Can this system work with existing blockchain networks?
Yes. While the patent outlines a conceptual framework, its principles can be implemented via smart contracts on platforms like Ethereum, Binance Smart Chain, or OKX Chain. The logic is chain-agnostic and adaptable.
Q3: Is a Certificate Authority (CA) necessary for every wallet?
Not necessarily. CA integration is optional and typically used in regulated or institutional contexts requiring identity verification. Individual users may opt for simpler models using only multi-sig and delayed transfers.
Q4: What happens if the high-permission address gets compromised?
Best practice dictates that the high-permission address should itself be protected by multi-signature authentication and cold storage. Additionally, it can be revoked or replaced through a governance process involving CAs or secondary approval nodes.
Q5: How does this compare to traditional multi-sig wallets?
Unlike standard multi-sig setups that focus solely on signing authority, this method adds time-based controls, recoverability, and dynamic permission delegation, offering greater flexibility and emergency response capabilities.

Real-World Applications
This permission model has broad applicability across sectors:
- Enterprises: Managing treasury funds with role-based access for finance teams.
- Decentralized Autonomous Organizations (DAOs): Enabling governance-controlled spending with audit trails.
- Family Trusts: Allowing guardians to oversee minor beneficiaries’ wallets.
- Exchanges: Implementing cold wallet recovery protocols without downtime.
Moreover, cited patents show follow-up innovations in areas like risk-based transaction filtering (Alibaba), delayed transfer cancellation (ComplexMe Tech), and blockchain identity binding—indicating industry-wide momentum toward smarter wallet architectures.
Security Advantages Over Standard Wallets
| Feature | Standard Wallet | This Method |
|---|---|---|
| Loss Recovery | Nearly impossible | CA-backed recovery path |
| Unauthorized Spend Prevention | Limited | Multi-layered checks |
| Access Flexibility | Static permissions | Dynamic delegation |
| Emergency Freeze | No native support | Built-in freezing mechanism |
These advantages position this method as a blueprint for next-generation self-custody solutions that balance autonomy with accountability.
Final Thoughts
As digital asset ownership grows, so does the need for intelligent, secure, and recoverable wallet systems. The blockchain wallet address permission management method detailed here offers a forward-thinking solution—one that integrates cryptographic security with administrative control.
