​
User Addresses

In LabTrace, every user is assigned a unique Algorand blockchain address that serves as their identity on the blockchain. This system provides the benefits of blockchain technology while eliminating the complexity and risks associated with traditional key management.

​
Address Generation

​
Automatic Assignment

When a user creates an account in LabTrace, the system automatically:
1

Generate Key Pair

Creates a new Algorand key pair (public and private keys) using cryptographically secure random generation
2

Derive Address

The blockchain address is derived from the public key using Algorand’s standard address format
3

Secure Storage

Private keys are encrypted and stored securely in the platform’s key management system
4

User Association

The address is permanently associated with the user’s account in the database

​
Address Format

Algorand addresses follow a specific format:
  • Length: 58 characters
  • Format: Base32 encoded with checksum
  • Example: 7ZUECA7HFLZTXENRV24SHLU4AVPUTMTTDUFUBNBD64C73F3UHRTHAIOF6Q

​
Key Management Architecture

Custodial Model

LabTrace manages all private keys on behalf of users, eliminating the risk of key loss

Encrypted Storage

Private keys are encrypted using enterprise-grade encryption and stored in secure vaults

Access Control

Multiple layers of access control protect key storage systems

Backup & Recovery

Comprehensive backup systems ensure keys can never be permanently lost

​
Benefits of Managed Addresses

​
No Key Management Burden

Users don’t need to manage, store, or remember private keys or seed phrases
Cannot lose access to blockchain identity due to forgotten passwords or lost devices
Blockchain operations happen transparently without user intervention
Organizations can manage multiple users without key distribution complexity

​
Security Advantages

  • Professional Management: Keys managed by security experts, not individual users
  • Redundant Storage: Multiple encrypted backups across different locations
  • Access Monitoring: All key usage monitored and logged
  • Incident Response: Rapid response to security incidents

​
User Identity on Blockchain

​
Transparent Operations

All blockchain operations are performed using the user’s assigned address: 
{
  "user_id": "user_123",
  "algorand_address": "7ZUECA7HFLZTXENRV24SHLU4AVPUTMTTDUFUBNBD64C73F3UHRTHAIOF6Q",
  "operations": [
    {
      "type": "project_creation",
      "transaction_id": "XYZ789...",
      "timestamp": "2024-01-15T10:30:00Z"
    },
    {
      "type": "file_upload",
      "transaction_id": "ABC123...",
      "timestamp": "2024-01-15T11:45:00Z"
    }
  ]
}

​
Blockchain Identity Benefits

  • Consistent Identity: Same address across all blockchain operations
  • Audit Trail: Complete history of user’s blockchain activities
  • Verification: Third parties can verify user’s actions independently
  • Integration: Address can be used with external Algorand tools

​
Address Funding & Management

​
Admin-managed Funding

1

Initial Funding

New addresses are automatically funded with a small amount of ALGO for transactions
2

Balance Monitoring

Admin monitors address balances and refunds as needed
3

Cost Management

Transaction costs are handled transparently by the platform

​
Transaction Costs

  • User Perspective: No direct transaction fees for users
  • Platform Managed: All blockchain costs handled by LabTrace
  • Transparent Pricing: Users see only platform subscription costs

​
Security Model

​
Multi-Layer Security

  1. Application Layer: User authentication and authorization
  2. Key Storage Layer: Encrypted private key storage
  3. Hardware Layer: Hardware security modules for key operations
  4. Network Layer: Secure communication protocols
  5. Blockchain Layer: Algorand’s native security features

​
Trust & Verification

​
Transparency

  • Public Addresses: All user addresses are visible on the blockchain
  • Verifiable Operations: Any transaction can be verified independently
  • Open Source: Core blockchain interaction code can be audited
  • Regular Audits: Third-party security audits of key management systems

​
User Control

While users don’t manage keys directly, they maintain control through:
  • Access Permissions: Control who can perform operations on their behalf
  • Operation Approval: Some operations may require explicit user approval
  • Audit Access: Users can view all operations performed with their address
  • Account Recovery: Secure account recovery processes

​
Comparison with Traditional Approaches

Traditional Web3

Users manage their own keys, high risk of loss, complex for non-technical users

LabTrace Approach

Platform manages keys securely, zero risk of user key loss, simple user experience

​
Trade-offs

Benefits:
  • Eliminates key management complexity
  • Reduces risk of permanent asset loss
  • Enables enterprise adoption
  • Provides professional security management
Considerations:
  • Users trust platform with key custody
  • Platform becomes single point of failure
  • May not suit users who prefer self-custody

​
Future Enhancements

Planned support for multi-signature addresses for enhanced security
Integration with hardware security modules for additional key protection
Optional key escrow services for users who want backup access
Support for users who want to manage their own keys while using platform services

​
Best Practices

For organizations using LabTrace:
  • Access Management: Implement proper user access controls
  • Regular Audits: Review user blockchain activity regularly
  • Backup Strategy: Understand platform’s backup and recovery procedures
  • Incident Planning: Have procedures for security incidents
  • Compliance: Ensure address management meets regulatory requirements
